The peptides we sell are supplied strictly as research compounds, for laboratory and research use only. They are not approved as drugs or supplements and are not sold for human or veterinary consumption or for diagnosing, treating, or preventing any condition. Researchers are responsible for understanding and following the laws and institutional rules that apply to them. This is general information, not legal advice.
How do I verify my batch's Certificate of Analysis?
Every vial is labelled with a batch number. Match that batch number to the corresponding Certificate of Analysis on our Lab Testing & COAs page. The COA lists the independently tested purity, potency, and sterility results for that exact batch.
Is the packaging discreet?
Yes. Orders ship in plain packaging with no product names, branding, or contents listed on the outside. Only standard shipping and return details appear on the label.
