Classical neuropeptide · 9 aa.
Oxytocin is a classical mammalian nonapeptide hormone and neurotransmitter. Synthesized in the hypothalamus and released from the posterior pituitary, it has well-characterized roles in parturition, lactation, and social behavior. Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.
Oxytocin is a classical mammalian nonapeptide hormone and neurotransmitter. Synthesized in the hypothalamus and released from the posterior pituitary, it has well-characterized roles in parturition, lactation, and social behavior.
Binds the oxytocin receptor (OXTR), a Gq-coupled GPCR. Peripheral actions include uterine contraction and milk ejection. Central/CNS actions are extensively studied in social behavior, pair bonding, and stress response. Structurally similar to vasopressin (differs in two residues).
Multiple injectable oxytocin products are FDA-approved (Pitocin, Syntocinon) for obstetric use. Intranasal research formulations are widely studied in behavioral research. WADA not prohibited.
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.
Oxytocin is a 9-residue peptide with molecular formula C43H66N12O12S2 and molecular weight of approximately 1,007.2 Da.
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 injectable oxytocin products are FDA-approved (Pitocin, Syntocinon) for obstetric use. Intranasal research formulations are widely studied in behavioral research. WADA not prohibited.
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.
