Kalpa Sermorelin 5 mg GHRH Analogue Research Vial for Labs

Kalpa Sermorelin 5 mg GHRH Analogue Research Vial

Kalpa Sermorelin 5 mg supplies the GHRH(1-29) analogue as a lyophilised vial. Sermorelin keeps the first 29 amino acids of growth hormone releasing hormone, the shortest fragment that still carries full activity, and it was sold historically under the pharmacy names Geref and Gerel. Its role is to signal the pituitary to release growth hormone, which is why it appears in research on the GHRH route rather than in steroid work, and no approved product remains on the market.

• Sermorelin (GHRH(1-29)) - 5 mg per lyophilised vial
• GHRH analogue, stimulates pituitary growth hormone secretion
• Half-life of the parent peptide 6.2 minutes after intravenous dosing in rats
• GMP-manufactured, HPLC-verified, COA on file per batch

How Sermorelin Works

Sermorelin binds the GHRH receptor on pituitary cells and triggers growth hormone release, which is a different route from the ghrelin receptor secretagogues such as Ipamorelin. The parent GHRH(1-29)-amide had a half-life of 6.2 minutes after intravenous dosing in rat work, and vendor texts quote 10 to 20 minutes without human confirmation, so the peptide clears far faster than the ghrelin route. That short window is the main practical difference between the two families in laboratory design.

Reconstitution and Storage

A 5 mg vial with 2 ml of bacteriostatic water gives 2.5 mg per ml, so the 400 to 500 mcg amount of vendor protocols measures 0.16 to 0.2 ml on a U-100 syringe; 1 ml of solvent gives 5 mg per ml and halves every volume. Add the water down the vial wall, do not shake, and keep the solution at 2-8 C without freezing. The other GHRH analogue on this line, Tesamorelin, is prepared with the same arithmetic.

Batch Sourcing and Sport Status

Every batch is produced under GMP conditions and checked by independent HPLC, with the Certificate of Analysis held for the batch. Side effects reported across unregulated GH peptides in a 2026 review are fluid retention, oedema and joint discomfort, and those findings describe the class rather than this peptide alone. Sermorelin is named directly in class S2 of the WADA prohibited list, so it is banned at all times in tested sport.
