About Sten Protocols

We stock research peptides and related compounds for laboratory groups, independent researchers and clinics running preclinical work. Everything is sold on the same terms: research use, documented by lot, no therapeutic framing.

Incoming lots are checked against supplier documentation before entering inventory, and anything with an incomplete record is quarantined rather than shelved. Release covers identity, purity, peptide content, water, residual solvent, endotoxin, heavy metals and bioburden.

Records are filed by lot number so the paperwork you receive matches the specific vial in your hands. Read more in the documentation standards guide.

We do not make therapeutic claims, offer dosing guidance, or sell to anyone indicating human or veterinary use. Orders that suggest otherwise are cancelled and refunded.

Sourcing, documentation and order questions all go to support@stenprotocols.com. A mailing address is available on request for institutional purchase orders.
