Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of growth hormone-releasing hormone (GHRH 1-29), the biologically active fragment of endogenous GHRH. It is studied in endocrine research models for its ability to stimulate pituitary growth hormone (GH) secretion through GHRH-receptor activation.

Sermorelin — Frequently Asked Questions

What is the sermorelin peptide?

Sermorelin is a synthetic analog of the first 29 amino acids of growth hormone-releasing hormone (GHRH 1-29). In research models it stimulates pituitary GH secretion through GHRH-receptor activation.

How does sermorelin differ from HGH in research?

They act at different points in the axis: HGH (HGH 191AA) is the growth hormone itself, while sermorelin is a releasing-hormone analog studied for stimulating the pituitary’s own GH secretion and preserving pulsatile release patterns in research models.

Is your sermorelin third-party tested?

Yes — every batch is tested by an independent third-party laboratory for purity and identity before it is released.

Where can I buy the sermorelin peptide?

You can buy sermorelin directly from MyGLP1Store in 5mg and 10mg research vials with same-day US shipping.

How should sermorelin be stored?

Store the lyophilized vial at -20°C. After reconstitution with bacteriostatic water, refrigerate at 2–8°C and follow standard laboratory protocols.

How much does sermorelin cost?

Sermorelin is priced per research vial at MyGLP1Store, in 5mg and 10mg sizes, with bacteriostatic water included at no charge. Ten-vial wholesale kits start at $304. Compounded prescription sermorelin obtained through a clinic or telehealth provider is priced per month of therapy and is a separate product category with a different cost structure.

Does sermorelin come as a nasal spray or tablet?

MyGLP1Store supplies sermorelin as a lyophilized powder in 5mg and 10mg research vials, which is the form used across the published GHRH 1-29 literature. Intranasal formulations appear in the pharmacokinetic literature, where intravenous and intranasal administration have been compared directly, and reported bioavailability by that route differs substantially from parenteral administration.

Sermorelin — Related Compounds & Research Reading

Sermorelin is a GHRH analog, so research designs usually pair or contrast it with GHRP-class secretagogues. Related third-party tested compounds and handling methodology:

• CJC-1295 No DAC (Modified GRF 1-29) — the stabilized GHRH analog sermorelin is most often compared with.
• CJC-1295 with DAC — long-acting GHRH variant for sustained-release study designs.
• Ipamorelin — the GHRP most frequently paired with a GHRH analog in combination models.
• Tesamorelin — GHRH analog with enzymatic-degradation resistance.
• GHRP-2 — secretagogue acting on the ghrelin receptor rather than GHRH-R.
