Buy Sermorelin Online — 3 sizes (2 mg–10 mg)
Mapped to comparative secretagogue studies — somatotropic signalling work.
Sermorelin is a truncated GHRH (1-29) analog, one of the shortest GHRH fragments that retains full biological activity. It is studied as a "natural" GH-axis research tool — driving endogenous GH release via the GHRH receptor.

Mechanism in the literature
Sermorelin binds the GHRH receptor in the anterior pituitary, stimulating endogenous growth-hormone release. Its short sequence (29 residues) is the minimal GHRH fragment that preserves receptor activity.
Research use-cases
- GHRH (1-29) — the minimal active GHRH fragment
- Stimulates endogenous GH release
- Shorter half-life than tesamorelin or CJC-1295
- Long history in GH-axis research
Often paired with
Buyers viewing Sermorelin typically also consider CJC-1295 No DAC, Tesamorelin and Kisspeptin-10. Each is in stock, sealed under nitrogen with a lot-matched CoA.
Handling in the lab
Reconstitute under sterile technique with bacteriostatic water. Typical volumes range from 1–3 mL depending on the target working concentration. Swirl gently — do not shake — to avoid peptide shearing.
Stacking and paired-compound work
Sometimes combined with ghrelin agonists (ipamorelin) for dual-pathway GH research.
Frequently asked
How does sermorelin compare to tesamorelin?
Tesamorelin is a stabilized GHRH (1-44) analog with better half-life. Sermorelin is the shorter GHRH (1-29) fragment — simpler structure but less protease-resistant.
How does it compare to CJC-1295?
CJC-1295 is GHRH (1-29) with additional stabilizing modifications (plus DAC in the longer-acting version). Sermorelin is the unmodified baseline.
Why short half-life?
Sermorelin lacks the protease-resistance modifications present in tesamorelin and CJC-1295. Half-life is measured in minutes rather than hours.
Is it still used in research?
Yes — its short action profile is desirable in some research designs precisely because it mimics native GHRH pulsatility.
