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. The GHRH 1-29 fragment retains the natural releasing activity of full-length GHRH, and researchers use it to evaluate pituitary responsiveness and growth-hormone secretory reserve. Its defined sequence supports reproducible peptide synthesis and quality control. The lyophilized powder is provided with documented purity and dosing flexibility. The lyophilized format provides excellent stability and simplifies reconstitution for reproducible dosing.
