CERTIFICATES OF ANALYSIS

COA Library

Independent, third-party certificates of analysis for Retatrutide — purity, identity, and endotoxin testing performed by an independent US laboratory.

Testing in progress

Every production batch undergoes third-party testing before it’s sold, but we only publish a certificate here once that report is back and lot-matched. Retatrutide’s COA is currently pending publication.

Need the report sooner? Email [email protected] with your order number and we’ll send the current report on file.
