Oxytocin is the endogenous nonapeptide hormone oxytocin, supplied by MyPeptides for laboratory research use only.
Oxytocin is the endogenous nonapeptide hormone oxytocin. MyPeptides supplies it as a lyophilised 2 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Oxytocin in social-behaviour and endocrine research models. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Oxytocin order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. Disulphide-bridged nonapeptide — supplied lyophilised so the bridge stays intact.

Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
Site was easy to use, checkout was fast, and the product arrived exactly when they said it would. Straightforward, no drama, high quality.
Really impressed with the packaging quality. Everything double-boxed, insulated and clearly labelled. Same day dispatch worked as promised.
Everything about this feels professional - from the site to the packaging to the paperwork. Purity assay matches what is on the label. Will keep ordering.
Been using peptides for research for years and MyPeptides is now my go-to. Consistent quality, quick turnaround, real documentation.
