British Dragon Sermorelin 5 mg GHRH(1-29) Research Standard

It is a lyophilized GHRH analogue supplied at 5 mg per sealed vial for laboratory research. The molecule is the first 29 amino acids of growth hormone releasing hormone, the fragment that retains full receptor activity, so it works as a standard agonist on the GHRH receptor of pituitary somatotrophs. It is sold as a research material, not as a finished medicine.

The lyophilized cake is dissolved in bacteriostatic water, run slowly down the inside wall of the vial and mixed by gentle swirling. Shaking is avoided because a peptide can be damaged by foaming and shear. The working solution is kept cold, protected from light and used within the window set by the study protocol, since the dry powder is much more stable than the reconstituted form.

Published work gives the parent GHRH(1-29) amide a half-life of about six minutes after intravenous dosing in animal studies, and vendor material quotes up to about twenty minutes. No human value is established for the research vial, but every figure in the range is short compared with a stabilised GHRH analogue, which is why assays treat the compound as an acute stimulus.

No human side effect profile is established for laboratory use of the powder, and none should be assumed from animal or cell work. Reported observations in the literature concern hormone release endpoints rather than toxicity. Handling follows normal research practice: gloves, eye protection and a ventilated bench, because the material is supplied as a research chemical rather than as a medicine.

The receptors are different. Sermorelin activates the GHRH receptor and mirrors the hypothalamic signal, while ipamorelin activates the ghrelin receptor, GHS-R1a, on the same pituitary cell type. Because the two mechanisms converge on growth hormone release but arrive by separate routes, the pair is commonly run together, and the Ipamorelin page covers the second route.

The 5 mg vial is listed on this page. Availability is shown on the product page, which also takes an email address for restock notices when the item is out of stock. Shipping details sit in the product data: international delivery plus a U.S. domestic route where stock allows, with one to two business days of handling after an order is placed.
