Legit Retatrutide: How to Verify Identity, Purity & Source
Verifying that Retatrutide is legitimate requires checking analytical documentation — specifically HPLC purity data and LC-MS identity confirmation. This page explains what to look for when evaluating a Retatrutide source.
What Makes Retatrutide Legitimate?
Legitimate Retatrutide is the correct peptide (confirmed by LC-MS identity) at the stated purity (confirmed by RP-HPLC) with batch-specific documentation. A legitimate source provides a Certificate of Analysis (COA) with actual test data, not generic or fabricated numbers.
How to Read a Retatrutide COA
A legitimate Retatrutide COA should include: the batch number, test date, HPLC purity result (expressed as a percentage), LC-MS molecular mass result, and the identity of the testing laboratory. The HPLC chromatogram and LC-MS spectrum should be available on request.
Red Flags to Avoid
Be cautious of sources that provide COAs without batch numbers, COAs with round-number purity values (e.g. exactly 99.00%), COAs that cannot be traced to a specific batch, or sources that cannot provide LC-MS identity data.

Frequently Asked Questions
How do I know if Retatrutide is legit?
Request a batch-specific COA with HPLC purity data and LC-MS identity confirmation. Verify that the COA includes a batch number and test date, and that the molecular mass matches the known value for Retatrutide.
What is the molecular weight of Retatrutide?
Retatrutide (LY3437943) has a molecular weight of approximately 4813 Da. LC-MS testing should confirm a molecular mass consistent with this value.
