Sermorelin

One of the earliest-studied GHRH analogs, with a long research history.

What is Sermorelin?

Sermorelin is a synthetic peptide corresponding to a fragment of growth-hormone-releasing hormone (GHRH 1-29). It has one of the longest research histories in this category and is sold strictly as a research material. Compare against HGH 191aa, the recombinant hormone itself.

Common questions

Sermorelin FAQ

Is sermorelin a peptide?

Yes — it corresponds to the first 29 amino acids of GHRH and is studied as a GHRH analog.

How do I know a vendor is legitimate?

Look for batch-specific, third-party Certificates of Analysis (COAs), transparent purity testing, U.S. sourcing, and a real reputation across independent review platforms. Our vendor reviews check all of these.

Does Peptides Uncaged sell Sermorelin?

No. We're an independent research and comparison resource. We link to vetted third-party vendors and disclose every affiliate relationship.

What it costs today

Vendor pricing moves constantly, and the sticker price on a vial is not the number that matters — cost per milligram is. Our sister index reads all four vendor storefronts directly and normalises every listing, so you can see who is actually cheapest right now.
