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 FDA-approved in the 1990s and voluntarily withdrawn for commercial reasons in 2008, it has the most extensive clinical history of any GHRH analog and remains a well-characterized reference compound for GH axis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 It was voluntarily withdrawn from the US market in 2008 for commercial reasons — not safety or efficacy concerns — leaving behind a substantial clinical literature.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.

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.

FAQ

Why was sermorelin discontinued if it was FDA-approved?
+
Serono voluntarily withdrew Geref from the US market in 2008 for commercial reasons — the market for pediatric GHD had shifted toward recombinant HGH. The withdrawal was not related to safety or efficacy concerns.
Is sermorelin legal to purchase for research in 2026?
+
Yes, for legitimate laboratory research. Sermorelin is not a scheduled controlled substance and is legal to purchase as a research chemical from compliant vendors.
