Recombinant 191-aa protein.
Human growth hormone (somatropin) is a 191-residue protein produced by recombinant DNA technology, structurally identical to endogenous pituitary hGH. It is among the most widely studied and clinically used peptide hormones. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.
Human growth hormone (somatropin) is a 191-residue protein produced by recombinant DNA technology, structurally identical to endogenous pituitary hGH. It is among the most widely studied and clinically used peptide hormones.
HGH binds the growth hormone receptor, a class I cytokine receptor, triggering receptor dimerization and JAK2 phosphorylation. Downstream signaling through STAT5 drives hepatic IGF-1 synthesis and direct metabolic and proliferative effects on target tissues.
Multiple recombinant somatropin products are FDA-approved for various indications (pediatric growth failure, adult GH deficiency, Turner syndrome, Prader-Willi, AIDS wasting). The research-grade material supplied by PeptideBros is not intended for clinical use. WADA prohibited (S2).
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
HGH (Somatropin) is a protein (191 amino acids, approximately 22,125 Da). Formula: C990H1528N262O300S7.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).
Multiple recombinant somatropin products are FDA-approved for various indications (pediatric growth failure, adult GH deficiency, Turner syndrome, Prader-Willi, AIDS wasting). The research-grade material supplied by PeptideBros is not intended for clinical use. WADA prohibited (S2).
All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
