British Dragon Tesamorelin 5 mg Modified GHRH Analogue Vial

It is a lyophilized GHRH analogue supplied at 5 mg per sealed vial for laboratory research. The molecule is the full releasing hormone with a modification that slows its breakdown, so it stimulates the GHRH receptor for longer than the short fragment. It is used as a standard in adipose tissue and lipolysis research, not as a finished medicine.

The lyophilized cake is dissolved in bacteriostatic water, added slowly down the inside wall of the vial and mixed by gentle swirling. Vigorous shaking is avoided, because foaming and shear can damage a peptide. The solution is kept cold and protected from light and used within the period set by the study protocol, because the reconstituted form is less stable than the dry powder.

The modification extends survival well beyond an unmodified GHRH fragment: general references give an elimination half-life of roughly twenty-five to forty minutes, and the approved product label lists under fifteen minutes after a subcutaneous dose. Every figure in that range is still short compared with an esterified steroid, so studies work with timed exposures rather than a single dose covering a day.

Clinical literature describes injection site reactions, joint discomfort and fluid retention among the reported effects, and the material is supplied here for laboratory work only, with no human application implied. Laboratory handling should use gloves, eye protection and a ventilated bench. Any unexpected physiological response after accidental exposure needs medical advice rather than self-treatment.

Both act on the GHRH receptor, so the receptor is not the difference. Tesamorelin is the full hormone with a stabilising modification and a longer working window, while sermorelin is the 29 amino acid fragment that clears within minutes. A study that wants a sustained stimulus uses the first, and one that models a natural pulse uses the second. The Sermorelin page describes the short end.

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.
