Overview
Sermorelin is the first 29 amino acids of natural GHRH, the shortest piece that keeps full activity. It was once approved for children with growth hormone deficiency.
How it works
It stimulates the pituitary to release growth hormone in natural pulses. Its half-life is only minutes.

Injection sites
Sermorelin 5mg is a freeze-dried powder. After mixing with bacteriostatic water, compounds like this are usually injected subcutaneously (subQ): into the fat just under the skin with a short insulin needle.
- Volume per site
- About 1 ml or less
- Needle
- 4 to 13 mm insulin needle, 29 to 31G
Finding it. Anywhere on the belly at least 5 cm from the navel, avoiding scars and the belt line. Pinch a fold of skin and inject into it.
Why it is used. The most-used subcutaneous site: easy to see, plenty of fat and steady absorption. Weekly GLP-1 pens list it first.
Watch out. Move each injection 2 to 3 cm from the last to avoid hard lumps.
- Volume per site
- About 1 ml or less
- Needle
- 4 to 13 mm insulin needle, 29 to 31G
Finding it. The middle of the front of the thigh, a hand-width below the hip and a hand-width above the knee.
Why it is used. Easy to reach seated and a good second site to rotate with the belly.
Watch out. Absorption can be a little slower than the belly.
- Volume per site
- About 1 ml or less
- Needle
- 4 to 13 mm insulin needle, 29 to 31G
Finding it. The fleshy back of the upper arm, halfway between shoulder and elbow.
Why it is used. A third site to rotate through so each spot rests longer.
Watch out. Hard to pinch and reach on yourself; a helper makes it easier.
Why these sites for Sermorelin 5mg
Subcutaneous (subQ)- Belly first. The abdomen has the most fat and the steadiest absorption, and you can see what you are doing.
- Short needle, small volume. About 1 ml or less per spot with an insulin syringe. Pinch the skin if you are lean.
- Move every time. Keep each injection 2 to 3 cm from the last to avoid lumps.
Every time: wash your hands, wipe the vial stopper and skin with alcohol, use a new sterile needle and syringe, and never share. See a doctor for spreading redness, heat, swelling, pus, fever or numbness. This is general guidance from standard nursing practice, not medical advice; a pharmacist or nurse can show you in person.
