Identity

What Sermorelin is

Growth hormone does not release on its own, the pituitary gland needs a signal called GHRH, and sermorelin is a lab-made copy of the first 29 building blocks of that signal. It was once an approved medicine in the United States before the manufacturer discontinued it. It remains the basis for a lot of compounded growth-hormone research today.

Sermorelin is a synthetic ghrh(1-29) analog of 29 amino acid residues. SBz Industries sells it for laboratory research.

Research

What the research has looked at

In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.

Human research on sermorelin dates back to the 1980s and 1990s, mostly small studies of growth hormone release, plus more recent retrospective chart reviews from clinics. A 2026 review grouped sermorelin among several growth-hormone peptides and noted that much of what is known about it today comes from older pharmacology work rather than fresh trials.

people2017

Researchers reviewed medical records for 105 men on testosterone therapy who were also prescribed a combination of sermorelin and two other growth-hormone-releasing peptides together, and 14 of those men met strict criteria for analysis. Blood IGF-1 levels, a marker of growth hormone activity, went up in that small group, though sermorelin was never tested by itself in this study.

review2026

This review grouped sermorelin with other growth-hormone peptides people buy online and sorted the evidence for each one into tiers, from regulatory-grade trial data down to no human studies at all. Sermorelin sat toward the older, better-studied end of that spectrum compared with newer compounds on the same list.

Handling

Mixing and storage

Lyophilized: -20C, protected from light. Reconstituted: 2-8C.

Full handling guide

01
Let it warm up
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
02
Add bacteriostatic water
Slowly, down the inside wall of the vial, never straight onto the powder.
03
Let it dissolve
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
04
Refrigerate and use
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.

Questions

Common questions about Sermorelin

What is Sermorelin?

Growth hormone does not release on its own, the pituitary gland needs a signal called GHRH, and sermorelin is a lab-made copy of the first 29 building blocks of that signal. It was once an approved medicine in the United States before the manufacturer discontinued it. It remains the basis for a lot of compounded growth-hormone research today. SBz Industries sells it for laboratory research only.

Was sermorelin ever an FDA-approved drug?

Yes. Sermorelin was the active ingredient in an FDA-approved product. The manufacturer later discontinued it, and sermorelin is not currently sold as an approved drug in the United States.

Has sermorelin been tested by itself in people?

Some of the available human data on sermorelin combines it with other growth-hormone peptides in the same treatment, which makes it hard to separate sermorelin's own effect from the mix.

How is Sermorelin reconstituted?

Sermorelin ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.

How should Sermorelin be stored?

Lyophilized: -20C, protected from light. Reconstituted: 2-8C. Vials ship in plain outer packaging with no product name on the outside.

Is Sermorelin tested, and can I see the results?

Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.

Who is permitted to purchase Sermorelin?

Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
