Where to Buy Sermorelin
Research-Grade Sourcing Guide (2026)
Sermorelin is the first 29 amino acids of endogenous GHRH — the minimal active fragment that retains full GHRH receptor affinity. FDA-approved in the 1990s and voluntarily withdrawn for commercial reasons in 2008, it has the most extensive clinical history of any GHRH analog and remains a well-characterized reference compound for GH axis research.

1. Research overview and regulatory context
Sermorelin (GHRH 1-29 NH2) was FDA-approved as Geref (Serono) for pediatric growth hormone deficiency diagnosis and treatment. It was voluntarily withdrawn from the US market in 2008 for commercial reasons — not safety or efficacy concerns — leaving behind a substantial clinical literature.
As a research compound in 2026, sermorelin is not available through pharmacies or prescribers. It is not a scheduled controlled substance and is legal to purchase for legitimate laboratory research.
Research use only. Sermorelin sold by Helixera Labs is for laboratory research use only. Not for human or veterinary use.
2. Sermorelin vs. CJC-1295 — key differences
| Property | Sermorelin | CJC-1295 no DAC | CJC-1295 with DAC |
|---|---|---|---|
| Sequence | GHRH 1-29 (native fragment) | Modified GHRH 1-29 (4 substitutions) | Modified GHRH 1-29 + DAC |
| Half-life | ~10–12 minutes | ~25–30 minutes | 6–8 days |
| GH release pattern | Pulsatile — most physiological | Pulsatile — extended pulse | Sustained elevation |
| Clinical history | FDA-approved (discontinued) | Preclinical | Preclinical |
Sermorelin's shorter half-life produces the most physiologically accurate GH pulse pattern of any GHRH analog — useful for research where mimicking endogenous GHRH secretion is the goal. See also: CJC-1295 no DAC overview and CJC-1295 with DAC overview.
