What is Sermorelin?
Sermorelin is the first 29 amino acids of growth-hormone-releasing hormone, the shortest fragment that retains full activity at the GHRH receptor. It is the reference GHRH analogue in secretagogue research and the backbone the CJC-1295 variants are built on. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.

What is Sermorelin studied for?
- GHRH receptor binding assays
- Pituitary growth-hormone release models
- Reference compound for GHRH analogue comparisons
- Pulsatility and feedback studies
All applications above are in-vitro or preclinical research contexts. Sermorelin is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot SERMO5-0318 show?
Every lot of Sermorelin is tested by an independent US laboratory before it is listed. The report for lot SERMO5-0318 is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot SERMO5-0318 result |
|---|---|---|
| Identity | MALDI-MS | Sermorelin · conforms |

| Purity | RP-HPLC (214 nm) | 99.8% |
| Endotoxin | USP <85> | ≤0.05 EU/mL |
How is Sermorelin handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
Frequently asked questions
Why 1-29?
It is the minimum fragment of the 44-residue hormone that retains full receptor activity, which makes it a practical synthetic reference.
How does it compare to the CJC-1295 forms?
Those are sermorelin's backbone with substitutions that slow degradation, and in the DAC form an albumin-binding complex. Sermorelin itself clears fastest.
Is Sermorelin for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
Also ordered as part of pituitary pulse.
