What the research says
Oxytocin is a nine-amino-acid hormone closed into a ring by a disulfide bond. It is made in the hypothalamus and released from the posterior pituitary. Besides its classic roles in labour and lactation, published research studies it in social behaviour, bonding and stress-response models. Oxytocin is the active ingredient of an injectable prescription product that received FDA approval for use during labour; PeptoClinic's vial is not that product and is not approved by the FDA. Supplied as lyophilized powder in a sealed vial.

How do I know a lot is what it claims to be?
From that lot's certificate of analysis, not from what the supplier asserts. The certificate names the laboratory that took the measurement, the date, the task number, the method and the purity found. PeptoClinic publishes the full reports uncropped, exactly as the laboratory printed them.
What is a certificate of analysis and how do you read one?
It is the report an analytical laboratory issues on a specific sample. Four things are worth checking: which compound it claims to have measured, by what method (HPLC for purity, mass spectrometry for identity), what figure it found, and whether the task number can be verified against the laboratory. A certificate with no verifiable task number is a picture.
