Description

Sermorelin is a synthetic analog of the first 29 amino acids of growth hormone-releasing hormone (GHRH 1-29), the biologically active fragment. In research settings it is studied for its role in stimulating endogenous growth hormone secretion, pituitary signaling, and GH-axis regulation in experimental models.

For Research Use Only. Not for human consumption.

Research FAQ

Sermorelin — frequently asked questions

A GHRH (1-29) analog studied for stimulating endogenous growth hormone secretion. For research use only. In laboratory settings, research interest commonly focuses on areas such as ghrh analog research, endogenous gh secretion studies, pituitary signaling research and gh-axis regulation studies.

No. Sermorelin is supplied exclusively as a research compound for in-vitro and non-human laboratory study. We do not provide health, dosing, or treatment guidance, and it must be handled by trained personnel following appropriate safety practices. All products are supplied strictly for laboratory and research use only and are not for human consumption.

Tested batches of Sermorelin are independently analysed to a target purity of ≥99% by HPLC, MS. The exact figure for each batch is reported on its Certificate of Analysis.

Sermorelin has a cas number of 86168-78-7, a molecular formula of c149h246n44o42s and a molecular weight of 3357.93 g/mol. Full technical details are listed in the technical data sheet on this page.

Sermorelin should be stored as follows: Store lyophilized at -20°C, protected from light. Stable at ambient temperature for short-term shipping. Reconstitute with bacteriostatic or sterile water for laboratory use. Refrigerate (2–8°C) after reconstitution.

Yes. Tested batches of Sermorelin are supplied with documentation of independent third-party purity and identity analysis, so researchers can verify exactly what they receive. The COA is available on this page or on request.

Sermorelin is packaged discreetly and shipped worldwide with tracked delivery, typically dispatched within 24 hours of confirmed payment. Checkout is secure cryptocurrency only (BTC, ETH, LTC, USDT).

Sermorelin is supplied as lyophilized white powder, sealed in a vial for laboratory research. Orders are packaged discreetly and shipped worldwide with tracking, typically dispatched within 24 hours of confirmed payment.

In the laboratory, Sermorelin is reconstituted by dissolving the lyophilized powder in a suitable solvent such as bacteriostatic or sterile water. Reconstitute with bacteriostatic or sterile water for laboratory use. Refrigerate (2–8°C) after reconstitution. Our reconstitution calculator (under Research Tools) can help determine the concentration of the prepared solution. This is laboratory guidance only, not dosing advice.

Yes. Sermorelin is also referred to as GRF 1-29. These names all refer to the same research compound.

Research compounds such as Sermorelin can generally be purchased for laboratory research, but legal status varies by country and by specific compound. Buyers are responsible for knowing and complying with the laws and import regulations in their own jurisdiction. It is supplied for research use only and is not for human consumption.

Yes. We can accommodate larger research orders of Sermorelin. Contact our research-support team to discuss bulk quantities, current availability and pricing.
