Description

Why researchers choose Owsa

  • UK-only fulfilment with free UK delivery and a clear 2pm UK same-day dispatch cutoff on business days.
  • Third-party COAs are published for selected lots; verify against the laboratory source where available.
  • Strengths without a published lot report are labelled on our Certificates of Analysis page.

Strengths and COAs

Choose from 5 mg, 10 mg, 15 mg (currently out of stock), 20 mg, 30 mg, 40 mg, 50 mg and 60 mg. Always match the lot on the vial to the certificate; a report for another lot is not evidence for a different vial.

Read the Retatrutide research overview, visit the Research Hub, and use the lab reconstitution calculator or Atlas for research documentation.

Laboratory-use notice

For qualified laboratory research use only. Not a medicine and not for human or veterinary consumption, dosing, injection, diagnosis or treatment.
