Sermorelin, also known as GRF 1-29, is a synthetic 29-amino-acid growth hormone-releasing hormone fragment that retains the full biological activity of GHRH for stimulating growth hormone release. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Sermorelin is investigated in research on growth hormone secretion, neuroendocrine regulation and related metabolic pathways, and is commonly applied in cell-based and preclinical studies. The lyophilized format provides good stability and reproducible reconstitution for consistent experimental dosing. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only.
