IMPORTANT: We recommend you read through the entire guide before you attempt to use your pen, to prevent misuse and common mistakes which can cause you to lose your peptide or damage your pen.
Ensure you have read all of the common mistakes and how to avoid them before you try to use your pen for the first time.
Your reusable Click Dose pen is designed to make dosing simple, accurate, convenient, and portable - whether you are using the Click. Dose. Go or the premium Click Dose Pro model. These instructions apply to both pen types, as they operate in a very similar way.
Unlike traditional syringes, reusable medication pens are designed to:
make dosing easier and more consistent
reduce waste
improve portability and convenience
allow fast and simple dose adjustment
provide a more user-friendly injection experience
allow you to use smaller length needles (4mm is the shortest available).
The pen body itself is reusable, while the medication cartridges and needle tips are replaced regularly as needed. These supplies are widely available online from many suppliers if preferred. However, we also stock compatible cartridges, needle tips, and accessories to make the process as simple as possible. Your pen uses:
standard 3ml sterile medication cartridges
standard screw-on needle tips
If this is your first time using a reusable medication pen - don’t worry. This guide will walk you through everything step-by-step, including:
inserting cartridges
attaching needle tips
priming the pen
setting your dose
administering injections
cleaning and maintenance
troubleshooting common beginner issues
Take your time, follow each section carefully, and you’ll quickly become confident using your pen.
Before getting started, take a moment to familiarise yourself with the different parts of your Click Dose pen system. If this is your first time using a reusable medication pen, don’t worry - it may look unfamiliar at first, but the process becomes very simple after a few uses. Your setup consists of:
a reusable pen body
a replaceable sterile cartridge - these hold 3ml liquid, which is the same as your standard medication vials (eg. Slim, Trim, Reignite, Glow Up...)
a new sterile needle tip for each injection
Below is an overview of the main parts you’ll be using.
Note: Click Dose Pro pens are not shown, but contain the same elements.
The reusable outer pen that contains the dosing mechanism and injection button. This is the main part of the system and is designed for long-term repeated use. The pen lid (sometimes called a cap) protects the pen and keeps it clean while stored or travelling. Always remove your needle tip after use, and put the lid back on before storing. The lid won't fit on with a needle tip still attached.
The section of the pen that holds your 3mL sterile cartridge securely in place during use.
This is clear so that you can easily see how much liquid is left in your cartridge.
See for example this cartridge here that has got approx 180 units remaining of GHKCU (we used this so the blue colour is easily seen in the example).
Note: this picture was taken before additional air was purged from the cartridge, hence the grey rubber stopper is still all the way at the end.
Used to select your desired dose before injection. The dose window will display the amount selected in units.
1 unit = 1 click = 0.01ml
Each pen can dose a maximum of 60 units (0.6ml) at once. If you need more than 60 units, hold the needle inside you, and wind up the remainder of your dose and inject again.
The image on the right is showing a dose of 10 units selected.
A sterile single-use needle that attaches to the end of the pen for each injection. They can be purchased in many lengths, typically 4mm and 5mm is best suited for our use.
Important:
Always use a new needle tip for every injection
Remove and dispose of the needle tip after use
Never leave a needle attached between injections
The sterile cartridge holds your medication inside the pen. You need 1 new cartridge to match each vial you reconstitute.
Each cartridge:
holds 3mL volume (same as most vials)
is replaced when empty
is compatible with standard reusable medication pens
Designed to help protect your pen during storage and travel. We recommend:
storing your pen inside the case when not in use - you can put the whole case in the fridge
avoiding direct sunlight and excessive heat
keeping supplies organised together
when you travel, you store extra needle tips in the slots
💉 Always use a new needle tip
Use a fresh sterile needle tip for every injection.
🚫 Never share your pen
Your pen is for personal use only and should never be shared with others.
❄️ Store your medication correctly
Follow the storage instructions provided for your medication and avoid excessive heat or direct sunlight.
🗑️ Dispose of sharps safely
Used needle tips and sharps should be placed into a sharps container.
✨ Prime before first use
Always prime the pen before your first injection to ensure medication flows correctly and air is removed. Instructions are below.
🎯 Check your dose carefully
Always double-check the dose shown in the dose window before injecting.
🔒 Remove the needle tip after use
Do not store the pen with a needle tip attached, as this can lead to leakage or air entering the cartridge.
👀 Inspect your cartridge before use
Do not use cartridges that appear cracked, leaking, damaged, or contaminated. The cartridges supplied by Illuminate Life come individually sterile sealed.
Your ClickDose pen is a reusable injection device designed to make dosing simpler, quicker, and more convenient than traditional syringes.
Instead of drawing medication into a syringe for every injection, the pen uses a replaceable 3mL cartridge system and a click-dose dial to deliver your selected dose.
The pen does not come prefilled with medication. You will:
prepare/reconstitute your medication as usual (the same process you may have done before if you have purchased from Illuminate Life - follow the instructions on the sheet we have provided)
transfer it into the sterile cartridge - use a syringe (1ml or 3ml are both fine)
then load the cartridge into the pen - slide the cartridge in place
The pen is simply the delivery device used to make injections easier and more convenient.
The number of units you will dial up for injection is the same as the number of units you would select on a syringe.
1 unit on a syringe = 1 click on a pen = 0.01ml
this is a standard unit of measure
no need to convert any maths or do any calculations
Before setting up your ClickDose pen for the first time, take a few moments to prepare your supplies and familiarise yourself with the process.
Once you’ve done it once or twice, it becomes quick and easy.
Before starting, make sure you have:
Your ClickDose pen
1 x sterile 3mL cartridge (you need 1 per vial)
Your prepared medication (already reconstituted to a liquid in a vial) - here's a link to the instructions on how to reconstitute if needed.
A new sterile needle tip to put on the tip of your pen (you need 1 per injection)
1 x Alcohol wipe
1 x syringe (1ml or 3ml are both fine) - this is to draw your liquid from the vial, and put it into the sterile cartridge
1 x needle or additional 1ml syringe for veting air from your sterile cartridge
A clean, well-lit workspace - wipe down the bench with anti-bacterial cleaner
Always wash and dry your hands thoroughly before handling:
cartridges
needle tips
medication
the pen itself
Keeping everything clean helps reduce contamination risk. This is especially important if you plan to use the same cartridge over a long period of time (30 days +) because contamination risk grows over time.
The ClickDose pen does not prepare medication for you. Before loading your cartridge reconstitute or prepare your medication as instructed - follow our reconstitution instructions provided with your product (you can view them all here also). After this you will transfer the medication into the sterile cartridge and insert the cartridge into the pen. Detailed cartridge instructions are covered in the next section.
These videos cover:
reconstituting your medication
transferring the medication into a sterile cartridge
loading your cartridge into the pen
injecting
Much more detail is provided below in the written instructions.
Before using your ClickDose pen, your prepared medication will need to be transferred into the sterile 3mL cartridge.
This process is simple and only takes a few minutes.
IMPORTANT: you should follow the instructions exactly, and do not skip the use of a purging needle otherwise you risk losing your peptide or damaging your cartridge.
Your prepared reconstituted medication
A sterile empty 3mL cartridge
Either: 2 x 1mL or 3mL syringe (either are fine)
Alcohol wipes
A clean workspace
Use an alcohol wipe to clean the grey rubber stopper on the sterile cartridge before inserting the syringe. Allow it to dry briefly.
Using your syringe:
Draw up air into your syringe, about the same amount as the amount of liquid as you plan to withdraw.
Insert the needle into your medication vial and insert this air into the peptide vial - doing this relieves the pressure in the vial. Skipping this step will make it difficult to draw up the entire liquid as the vacuum will be too strong.
Slowly draw up the liquid.
Remove any large air bubbles if needed. Do this by holding the needle tip facing upright, and tap your syringe to encourage the air bubbles to move to the top. Then push the plunger to push the air bubbles out of the syringe.
Take your time for accuracy.
IMPORTANT: IF YOU DO NOT USE A NEEDLE TO VENT AIR OUT OF YOUR CARTRIDGE WHILE PUSHING YOUR PEPTIDE IN, THEN PRESSURE WILL BUILD AND THE GREY RUBBER STOPPER WILL LIKELY POP OUT. THIS WILL RESULT IN ALL OF YOUR VALUABLE PEPTIDE BEING LOST. DO NOT SKIP THIS STEP.
The sterile cartridges are currently full of air, and trying to force 3ml of liquid in will result in you likely losing some (or all) of your peptide.
You now need to release the air from the cartridge through a process called purging (sometimes also called venting). Do not skip this step - this is a common mistake and has resulted in some people losing some or all of their peptide.
Use either a needle tip (like the screw on ones for a 3ml syringe) or an insulin syringe for this step. We have shown both options in the images below. If you use an insulin syringe, you should entirely remove the plunger from the syringe so the air can flow freely.
insert the needle into the sterile cartridge (the end with the silver crimp). The purpose of this is to provide an outlet for air to to escape from the cartridge, while you are injecting the liquid in with another syringe.
Leave this needle in for the next step.
Option 1. Use a removable needle from a 3ml syringe.
Insert needle at an angle.
Option 2. Use a 1ml insulin syringe.
Completely remove the plunger so that air can flow freely
Insert the syringe into the sterile cartridge stopper and slowly inject the liquid inside.
✔ Inject slowly - this allows the air to release through your purging needle
✔ Avoid forcing liquid in too quickly
✔ Repeat as needed until desired volume is reached. The cartridges only hold 3ml volume at a time.
✔ Leave the purging (second) needle in for this process until all liquid has been inserted
✨ Glow Getter Tip
Slow and steady wins here. Injecting the liquid slowly into the cartridge may help reduce bubbles and make the process smoother.
Do not skip the use of the puging needle shown in the previous step. Inject slowly to allow air to adequately vent out while you are injecting your peptide.
Your ClickDose pen uses a replaceable sterile 3mL cartridge system. Use a new cartridge for each new vial of medication you are using. Do not re-use cartridges, as they will no longer be sterile and present a bacterial contamination risk. Once your medication has been prepared and transferred into the cartridge, you’re ready to load it into the pen. Take your time during your first setup, it becomes very easy after a couple of uses
Remove the outer pen cap and place it aside on a clean surface.
Gently twist the pen body apart to access the cartridge holder section. You should now see the internal compartment where the cartridge sits.
Carefully place your prepared 3mL cartridge into the cartridge holder.
✔ Ensure the cartridge sits straight
✔ Do not force the cartridge into place
✔ Handle carefully to avoid cracks or damage
Screw the pen body back together firmly until secure. Do not overtighten. Once assembled correctly, the cartridge should feel secure inside the pen with no movement or rattling.
Before attaching a needle tip:
✔ Ensure the cartridge is seated properly
✔ Ensure the pen closes fully
✔ Check for any visible leaks or damage
If anything appears unusual, remove the cartridge and inspect all components before continuing.
🔄 Cartridges are replaceable, but the pen itself is reusable.
When your cartridge is empty:
Remove it from the pen
Dispose of it safely
Insert a new prepared cartridge
✨ Glow Getter Tip
If the pen does not screw together easily, avoid forcing it. Double-check that the cartridge is sitting correctly and aligned properly inside the holder.
Your ClickDose pen uses disposable sterile needle tips designed for comfortable, precise injections. Each needle tip should only be used once and replaced after every injection.
✔ Wash your hands
✔ Ensure your cartridge is already inserted into the pen
✔ Use a new sealed sterile needle tip
✔ Check the packaging is intact before use
Peel off the protective seal from the new needle tip. Each needle tip should be individually sealed. Do not use the needle if:
the seal is damaged
the packaging is already open
the needle appears bent or contaminated
Screw the needle tip straight onto the pen until secure. The needle tip should feel secure without wobbling. Do not overtighten.
Carefully pull off the larger plastic outer cap and keep it nearby. You’ll need this later to safely remove the needle tip after your injection.
Remove the small inner protective cap to expose the needle. Your pen is now ready for priming.
⚠️ Needle tips are extremely fine and very sharp.
Our ClickDose pens use standard insulin pen needles (which we supply or you can purchase elsewhere). We supply the following variety:
32G ultra-fine needles
4mm short-length tips
Many people find these significantly more comfortable and less intimidating than traditional syringe needles.
⚠️ Never reuse needle tips.
Reusing needle tips may:
increase discomfort
blunt the needle
increase contamination risk
affect injection quality
Always use a fresh sterile tip for every injection.
✨ Glow Getter Tip
The 4mm needle tips are designed for subcutaneous injections and are intentionally very short - many Glow Getters are surprised by how comfortable they feel compared to standard syringes.
Before your first injection, your ClickDose pen needs to be primed. Priming is a quick process that:
✔ removes air from the system
✔ ensures medication is flowing correctly
✔ helps improve dosing accuracy
Air can sometimes be present:
inside the cartridge
inside the needle tip
inside the pen mechanism
If the pen is not primed properly, this may affect how accurately medication is delivered. Priming helps ensure your pen is ready to inject correctly.
✨ Prime:
before first use
after inserting a new cartridge
if the pen has not been used for some time
(no need to prime before every injection)
Ensure a new sterile needle tip is attached securely and both needle caps have been removed.
Turn the dose dial to a small amount - usually 1-2 units is enough. This small amount is used only for priming - not for injection.
Point the needle upward toward the ceiling.This helps air bubbles rise toward the top.
Gently tap the cartridge holder with your finger to help move any air bubbles upward. This is similar to how you would remove an air bubble from a syringe (same technique really)
Press the injection button fully. Watch the needle tip closely. You should see a small droplet of liquid appear at the needle tip. This confirms the pen is primed and medication is flowing correctly.
Don’t worry, this can happen occasionally during first setup.
Simply repeat the priming steps again until:
✔ liquid appears
✔ airflow is removed
✔ the pen is functioning normally
⚠️ A small amount of medication is used during priming. This is normal and expected.
✨ Glow Getter Tip
Many people only need to fully prime the pen during initial setup or after changing cartridges. Once the system is flowing properly, future use is usually very quick and easy.
One of the biggest benefits of the ClickDose pen system is how simple and precise dosing can feel. Instead of manually measuring with a syringe each time, the pen uses a click-dose dial that allows you to select your dose using unit increments.
The dial at the end of the pen controls how much medication will be delivered during your injection.
As you turn the dial:
✔ the dose number increases
✔ clicks can usually be felt/heard
✔ the selected amount appears in the dose window
Take your time and always double-check the number displayed before injecting.
Before setting your dose:
✔ your cartridge should already be inserted
✔ a needle tip should already be attached
✔ the pen should already be primed
If you have not primed the pen yet, complete the priming steps first.
Slowly rotate the dose dial until your desired dose appears in the dose window.
✔ Turn slowly
✔ Watch the number carefully
✔ Stop once the correct dose is displayed
⚠️ Important: How many clicks?
1 click on a pen = 1 unit on a syringe
both are standard measures, equal to 0.01ml of liquid
if you usually do 50 units on a syringe, you will do 50 clicks on a pen - no maths or conversions are necessary
Before injecting:
✔ Confirm the number shown matches your intended dose
✔ Ensure the dial has stopped correctly
✔ Avoid rushing this step
Accurate dosing is important.
Don’t panic ✨
If you accidentally turn past your intended dose:
✔ simply turn the dial backwards to reduce the number
✔ no medication is wasted unless the injection button is pressed
⚠️ The pen does not automatically know your medication strength or protocol.
The dose dial only controls the volume delivered.
Always ensure you:
understand your dosing instructions
know your medication concentration
confirm your intended dose carefully
If you are ever unsure, you can always send us a message on Whatsapp (0432 245 927) or on the website live chat for confirmation. You can also view the reconstitution guides here to find your correct dose listed.
Once your dose is set:
✔ choose your injection site
✔ clean the area if required
✔ insert the needle as instructed
✔ press the injection button fully to deliver the dose
Detailed injection guidance on where to inject is provided here.
✨ Glow Getter Tip
If you wind it too far, simply wind the dial back - no harm done.
Once your dose has been selected, you’re ready to inject. The ClickDose system is designed to make injections feel quick, simple, and more comfortable, especially when using the ultra-fine 4mm needle tips. Take your time and follow each step carefully ✨
ClickDose pens are designed for subcutaneous injections (into the fatty layer under the skin). If you are new to giving yourself injections, we strongly suggest you also read this detailed guide on correct injection technique and locations.
Common injection areas include:
✔ Abdomen/stomach area
✔ Upper thigh
✔ Back of the upper arm
Avoid:
irritated skin
bruised areas
scars
areas that are tender or swollen
Clean the injection site using an alcohol wipe and allow the area to dry completely before injecting. If you don't allow it to dry, it can sting.
Hold the pen comfortably, pinch your fatty tissue between your fingers and insert the needle tip into the skin. A 90 degree angle is fine as the needle tips are only 4mm long.
The 4mm needle tips are intentionally very short and fine, so most people find them significantly more comfortable than traditional syringe needles.
Press the injection button fully until the dose has been delivered.
✔ Press steadily
✔ Do not release early
✔ Keep the needle in place while injecting
You may hear or feel the click-dose mechanism during delivery.
After pressing the button fully, keep the needle under the skin for approximately 5–10 seconds.
This helps ensure the full dose is delivered properly. Don't rush the process.
Remove the pen gently from the skin. A tiny droplet at the injection site occasionally can happen and is usually normal.
✔ Carefully recap the outer needle cap
✔ Remove the used needle tip safely
✔ Dispose of sharps appropriately
✔ Replace the pen cap for storage
Do not store the pen with a needle attached.
⚠️ Injection technique can take a little practice at first. We have a lot more tips and videos on correct injection technique on this page.
Some stinging, redness and even a small bruise at the injection site are all completely normal (known as injection site reactions). Most people become much more confident after only a few uses.
Correct storage helps protect:
✔ your medication
✔ your cartridge integrity
✔ dosing accuracy
✔ overall pen performance
Taking a few simple precautions can help keep your ClickDose system working smoothly and safely.
Injectable medications require refrigeration after preparation/reconstitution.
❄️ You can store your whole pen in the fridge between uses
❄️ Ensure your pen cap is on
❄️ No need to take the cartridge out of the pen for storage
❄️ Return to the fridge promptly after use
❄️ Keep away from freezing temperatures
⚠️ Don't leave the needle tip on after use or when storing.
Heat is one of the biggest enemies of injectable medications, and can warp the plastic elements of your Click. Dose. pen.
Avoid leaving your pen or cartridges:
☀️ in direct sunlight
🚗 inside parked cars
🔥 near heaters or hot windows
🏖️ in hot bags or outdoor areas
Excessive heat may damage medication quality and affect cartridge performance.
Always remove the needle tip immediately after your injection. Storing the pen with a needle attached may:
allow air into the cartridge
cause medication leakage
affect dosing accuracy
increase contamination risk
Once the needle tip is removed:
✔ safely dispose of it
✔ replace the pen cap
✔ store the pen in it's case
It's fine to place your pen and the whole case in the fridge between uses. Your ClickDose storage case is designed to:
✔ protect the pen during travel
✔ reduce accidental damage
✔ keep supplies organised
✔ make transport easier and more discreet
Many Glow Getters like keeping:
spare needle tips
alcohol wipes
spare cartridges
their pen
…all together in one place.
When storing your pen:
✔ keep the cap on
✔ store in a clean dry place
✔ avoid dust or contamination
✔ keep supplies sealed until use (ie. keep the sterile cartridges in their individually sealed packages.
The reusable pen system is designed to be much more travel-friendly than traditional syringes. Compared to carrying multiple syringes and supplies, the reusable pen system is compact, discreet, easier to organise, quicker to use on the go. Whether you’re heading away for a weekend, flying interstate, or travelling internationally, a little preparation can help make things simple and stress-free.
Packing Your Supplies
Before travelling, make sure you have:
✔ Your ClickDose pen
✔ Enough medication for your trip
✔ Spare sterile cartridges if needed
✔ Extra needle tips
✔ Alcohol wipes
✔ Your storage case
✔ An insulated pouch or ice pack if the medication will be out of refrigeration for long periods of time
It’s always a good idea to pack a little extra in case of delays or schedule changes.
Many people travel with injectable medications every day.
For flights:
✔ keep medication in carry-on luggage
✔ use an insulated pouch or ice pack if refrigeration is required - like these ones we sell
✔ avoid checked baggage where temperatures can fluctuate (and your bag could go missing!)
Airport security commonly sees:
injectable medications
insulin pens
syringes
needle tips
…and these items are generally very routine for screening staff. Unless told otherwise, you can leave your Click Dose Pen in your carry on luggage during X-Ray screening.
If flying:
✈️ keep medication in your carry-on luggage
✈️ avoid checked baggage where temperatures can fluctuate significantly
Carry-on storage helps:
✔ maintain safer temperatures
✔ reduce risk of loss or damage
✔ make access easier during travel
If your medication requires refrigeration:
❄️ Use an insulated pouch or cooler bag like these ones we sell
❄️ Add an ice pack if needed - usually good if you'll be in transit for 24 hours +
❄️ Avoid direct contact between medication and frozen ice packs where possible
The goal is to keep the medication cool, not frozen.
Avoid Heat Exposure
Heat can damage many injectable medications.
Avoid leaving your pen or medication:
☀️ in direct sunlight
🚗 inside parked cars
🔥 near heaters or windows
🏖️ in hot luggage or beach bags
Even short periods of extreme heat may affect medication quality.
Once you arrive:
✔ place medication into a fridge if possible
✔ keep supplies clean and dry
✔ store the pen safely inside its case when not in use
If refrigeration is unavailable temporarily, try to keep medication as cool and temperature-stable as possible.
Needle tips and syringes are commonly transported for medical use. For easier travel and disposal:
✔ keep tips sealed in original packaging
✔ pack them neatly in your case or pouch
✔ dispose of used sharps safely wherever possible
✨ Glow Getter Tip
Some hotels provide sharps disposal if you ask the concierge (usually large chain hotels), or some public toilets will have sharps disposal containers. Otherwise, keep the needle tips in their individual plastic packaging and take them home with you.
If something doesn’t feel quite right with your ClickDose pen - don’t panic ✨
Most issues are very simple to fix and are usually related to setup, priming, cartridge positioning, or needle tips. Here are some of the most common things others run into when learning their new pen system.
“There's too much pressure in the cartridge and I can't add my liquid”
✔ You haven't added a venting needle (Step 12 in this video)
✔ Venting needle is not positioned correctly
✔ You're trying to inject too quickly
Watch for Step 12 in this video (05:45) and follow this process
use a second venting needle to allow air to escape from the cartridge
reposition needle within the sterile cartridge
inject slowly
"The grey rubber stopper came out of the cartridge when I was filling it up, and I lost all of my peptide"
✔ You haven't added a venting needle (Step 12 in this video)
✔ Venting needle is not positioned correctly
✔ You're trying to inject too quickly
Watch for Step 12 in this video (05:45) and follow this process
use a venting needle to allow air to escape from the cartridge
reposition needle within the sterile cartridge to ensure air is adequately able to escape
inject slowly, very slowly
“No medication is coming out”
✔ The pen has not been primed
✔ The needle tip is blocked
✔ The cartridge is empty
✔ Air is still trapped in the system
Attach a new needle tip
Prime the pen again
Hold the pen upright while priming
Ensure a droplet appears before injecting
✔ The cartridge is not seated correctly
✔ The pen body is not assembled fully
✔ The dose dial is already at maximum available volume
Unscrew the pen carefully
Reinsert the cartridge
Reassemble gently without forcing
Check remaining medication volume
✔ The pen has reached maximum available dose
✔ The mechanism is under pressure
✔ The cartridge is empty
Check whether medication remains in the cartridge
Reset the dial carefully
Ensure the injection button is fully released
Never force the dial.
Good news No medication is wasted unless the injection button is pressed.
Simply rotate the dial backwards until the correct dose appears in the dose window.
Small bubbles can occasionally happen and are usually not a major issue. To reduce bubbles:
✔ inject liquid slowly into the cartridge
✔ prime the pen properly
✔ tap the cartridge gently before priming, holding the needle end up so the air bubble goes to the correct end for removal
Large air pockets should be removed during the priming process.
A tiny droplet can sometimes happen and is usually normal.
This may occur if:
✔ the needle was removed too quickly
✔ the pen wasn’t held in place long enough after injecting
hold the pen in place for 5–10 seconds after pressing the button fully
remove the pen slowly
Some medications naturally sting more than others.
Things that may help:
✔ allowing refrigerated medication to warm slightly before use
✔ injecting slowly
✔ rotating injection sites
✔ using a fresh needle tip every time
✔ The cartridge is misaligned
✔ The cartridge is not fully seated
✔ The pen is being overtightened
remove the cartridge
reinsert carefully
ensure it sits straight
screw together gently
Never force the pen closed.
This happens sometimes, don’t stress.
However, storing the pen with a needle attached may:
allow air into the system
increase leakage risk
affect dosing accuracy
Simply remove the needle tip and continue normal storage.
You are definitely not alone ✨
Most people feel nervous the first few times.
The good news is:
✔ the 4mm / 32G needle tips are extremely thin and not very long
✔ many people find the pen much easier than syringes
✔ confidence usually builds very quickly after a few uses
Take your time and go step-by-step.and watch the videos for more guidance on how to do it correctly.
