Ready-to-use starter kit
Ipamorelin is a synthetic peptide classified as a selective growth hormone-releasing peptide (GHRP). At the molecular level, it binds to specific ghrelin receptors in the pituitary gland, triggering a natural pulse of growth hormone without elevating cortisol or prolactin levels. In laboratory and animal studies, scientists are investigating this molecule for its potential role in cellular recovery, metabolic regulation, and aging processes. This product is a research-grade chemical intended strictly for laboratory use and is not an approved medication or supplement for human consumption.

Ipamorelin is a selective growth hormone releasing peptide (GHRP) that stimulates natural growth hormone production from the pituitary gland. Known for its clean profile with minimal side effects on cortisol and prolactin levels, making it ideal for body composition, recovery, and anti-aging applications.
Selective GHS-R1a agonist — no cortisol/prolactin elevation GH +4-8x baseline (Raun 1998) Standard CJC-1295 partner Clean GH pulse without HPA-axis confounders
Injectable Ipamorelin provides direct systemic delivery for consistent GH pulse stimulation. Binds selectively to ghrelin receptors in the pituitary to stimulate natural GH release without affecting cortisol, prolactin, or causing significant hunger.
Stimulates pituitary gland to release growth hormone naturally with consistent elevation 30-60 minutes post-injection, maintaining natural pulsatile patterns.
Increases insulin-like growth factor-1 production through natural GH pathways, mediating growth hormone's beneficial effects on muscle, bone, and tissue.
Supports cellular regeneration, collagen synthesis, and metabolic function through enhanced growth hormone pathways without disrupting natural hormone balance.

[Step by step]
6 steps from a sealed vial to the injection. Plain language.
Peptide vial (10 mg), bacteriostatic water vial, 1 larger syringe (3-5 ml) for drawing water and 1 insulin (1 ml) for doses. Alcohol swabs for sanitizing the caps.
Wash your hands before starting.
Wipe the rubber cap of the water vial with an alcohol swab. Insert the needle, invert the vial and draw exactly 2 ml. Get the exact volume from the calculator.
Larger syringe = smaller error in volume.
Wipe the peptide vial cap. Tilt the vial 45° and release the water SLOWLY down the inner wall. Peptides are fragile — a direct stream onto the powder denatures them.
SLOWLY · DOWN THE WALL · NOT ONTO THE POWDER.
Hold the vial between both palms and swirl slowly. DO NOT shake or flip sharply — peptides break down under mechanical stress.
DON'T SHAKE. Like tea — not like a cocktail.
The powder should fully dissolve. The solution is clear, no visible particles. If cloudy or with sediment — discard (wrong water or bad batch).
Clear = OK. Cloudy = discard.
With the insulin syringe draw the exact marks from the calculator. Swab the skin (abdomen 5 cm around the navel, thigh, or buttock), pinch a fold, insert at 45-90° and inject slowly.
Rotate sites every injection to avoid lipohypertrophy.
