The needle is the thing that stops people, so here it is in plain words: what it actually is, where it goes, what the first one is like, what it feels like, and what to do if something is off.
What it actually is.
An insulin syringe. The needle is thinner than a sewing pin and about as long as a grain of rice, and it goes into the layer of soft fat just under the skin, not into muscle and nowhere near a vein. It is the same syringe people with diabetes use several times a day, for years. The whole thing, from taking the cap off to putting it down, takes under a minute once you have done it twice.
There is nothing to learn about the syringe itself. It is a single-use, pre-attached needle with a plunger, marked in units along the side. The results sheet gives the units to draw for each compound and the calculator gives them for any vial you ever hold. The vial arrives as a powder with a small vial of water. You add the water, let it dissolve, and draw the dose into the syringe. The results sheet tells you how much water and how much to draw, and the calculator does the arithmetic for any vial. Mixing is the part people worry about; it is the part that turns out to be easy.
Where it goes.
The stomach, a hand's width either side of the navel, or the front of the thigh. Both have a layer of soft fat that the needle goes into, and both are places you can see. Pinch a fold of skin, put the needle in at a shallow angle or straight in, push slowly, count to three, take it out. Move to a different spot each time, a few centimetres from the last; the sheet says rotate sites, and this is all it means.
For a repair peptide on a local injury, near the injury is better than far from it, as long as it is still soft tissue and not the joint itself. For everything else, the site does not matter and comfort does.
See which of these belong in your protocol.
Get startedThe first one.
Wash your hands. Wipe the top of the vial and the spot on your skin. Draw the dose the sheet gives, tap out the air bubble, and push the plunger until a drop appears at the tip. Pinch, insert, push slowly, count to three, withdraw. Press a clean tissue on the spot for a moment. Put the syringe in the lidded container. That is the whole of it.
The results sheet links two short videos, one for mixing and one for the injection. Watch both once before the first one and you will not need them again. If it is still the thing holding you back, message us before you order and we will do the first one with you on a video call. The reconstitution calculator gives the line to draw to, the unit converter turns the sheet's dose into units, and the site rotation map says where today. The glossary has every word on this page.
What it feels like.
A pinch, then nothing. Most people describe it as less than a blood test and are a little embarrassed by how much they had worried. The push itself should be slow; a fast push is what stings, and on the energy compound a fast push is what causes flushing. A small drop of blood at the site is normal. A small bruise the next day is normal. Both go.
Some compounds have a feeling that is not the needle: the fat-loss compounds cause nausea when a dose rises too fast, and the sleep compound causes grogginess when the dose is too high. Those are on the sheet next to the compound, with what to do, and the side-effects answer goes through them.
What to do if.
If the site is hot, red beyond a coin's width, swollen or painful the next day, message us with a photograph and do not inject there again until it has settled. If you bleed more than a drop, press longer; it happens with thin skin and it is not a problem. If you are unsure whether the dose was drawn correctly, do not guess: the calculator gives the answer in seconds. If you missed a day, take the next one at the usual time and never double up.
If anything happens that the sheet did not describe, stop and message. The storage guide covers what to do with a vial that was left out, and the first-protocol guide covers the week around the first injection. Take it to a doctor who knows you before you begin.
The short version.
- It is an insulin syringe: a needle thinner than a pin, into soft fat, under a minute.
- Stomach or thigh, a different spot each time, a few centimetres from the last.
- Wash, wipe, draw, tap, pinch, insert, push slowly, count to three, withdraw, press.
- It feels like a pinch. A fast push is what stings; go slow.
- A drop of blood and a small bruise are normal. Heat, spreading redness or swelling are not.
- Missed a day: take the next one at the usual time. Never double up.
- If the needle is the problem, message before you order. We will do the first one with you.

Get startedQuestions
Does it hurt?
A pinch, then nothing. Less than a blood test for most people. Pushing slowly is what keeps it that way.
Where do I inject peptides?
The soft fat of the stomach, a hand's width either side of the navel, or the front of the thigh. A different spot each time.
Can I inject in the same place every day?
No. Move a few centimetres each time so the skin recovers. The sheet says rotate sites; that is all it means.
What needle size do I need?
The insulin syringes that come with the order. You do not need to buy or choose anything.
What if I get a bruise?
Normal. It goes in a few days. Heat, spreading redness or swelling are the things to message about.
