— FAQ
Sermorelin questions, answered
- 01
What is sermorelin?
Sermorelin is GRF (1-29) — the 29-amino-acid N-terminal fragment of human growth-hormone-releasing hormone that retains full activity at the GHRH receptor (CAS 86168-78-7). It is a staple of growth-hormone-axis research and is supplied for laboratory research use only.

- 02
How does sermorelin differ from tesamorelin?
Sermorelin is the truncated GHRH fragment (residues 1–29), while tesamorelin is a full-length GHRH (1-44) analog carrying a trans-3-hexenoic acid modification that improves its stability. Both are studied as GHRH-receptor agonists; the right choice depends on your research question.
- 03
How is sermorelin prepared for laboratory use?
Reconstitute the lyophilized powder with bacteriostatic water using gentle swirling rather than shaking. The peptide calculator converts your target concentration into an exact diluent volume.
- 04
How do I check the purity of my sermorelin lot?
Recent sermorelin lots have assayed at ~98.9% by in-house HPLC with independent third-party confirmation. Find your batch number's certificate in the lab report index or through lot lookup.
