Latest Third-Party Batch Test Results: Retatrutide 10 mg Verified at 99.01% Purity

Latest Third-Party Batch Test Results: Retatrutide 10 mg Verified at 99.01% Purity

At Prime Labs, Trust Isn’t Claimed—It’s Verified

Anyone can make claims about quality. That’s why we continue to randomly select products from our inventory and send them to an independent third-party laboratory for verification.

Our newest random batch test has been completed by Freedom Diagnostics, an independent U.S. analytical laboratory using HPLC-UV and LC-MS (mass spectrometry) methods to confirm both identity and purity. Freedom Diagnostics states that it performs purity, identity, and optional net content testing using these analytical methods for research peptides. 

Latest Random Batch Results

Product Tested: Retatrutide 10 mg

Independent Laboratory: Freedom Diagnostics

Report Date: August 5, 2026

Results

  • ✅ Identity: Confirmed
  • ✅ Purity: 99.01%
  • ✅ Net Peptide Content: 11.13 mg
  • ✅ Appearance: White lyophilized powder

These findings indicate:

  • The peptide identity matched Retatrutide.
  • The sample demonstrated 99.01% purity, meaning very little detectable impurity was present.
  • The vial contained 11.13 mg, exceeding the labeled 10 mg amount in the tested sample.

Why Third-Party Testing Matters

Independent laboratory testing helps remove guesswork by verifying:

  • Is the peptide actually what the label says it is?
  • How chemically pure is the sample?
  • Does the vial contain the expected amount of peptide?

A quality Certificate of Analysis should include:

  • Batch identification
  • Independent laboratory information
  • Purity testing (HPLC)
  • Identity confirmation (Mass Spectrometry)
  • Net peptide content
  • Chromatogram and mass confirmation data
  • Report dates and accession information 

Our Commitment

Prime Labs believes quality assurance should be ongoing—not a one-time event.

That’s why we perform random batch testing throughout the year instead of relying solely on manufacturer documentation. Independent verification provides an additional layer of confidence that the products we receive continue to meet our quality standards.

As new batches are randomly selected and analyzed, we’ll continue publishing the results for our customers to review.
