V8 Peptides — Engineered Performance

Analytical Verification

Testing & Certificate of Analysis

Our lots are tested by an independent lab, Accumark Labs, and each published Certificate of Analysis is specific to its lot. We are adding certificates as reports come back. We give you measured evidence — not an unsupported purity claim.

Testing methods

HPLC Purity Analysis

High-performance liquid chromatography measures compound purity — measured purity is reported on each certificate, not just claimed.

Identity, Endotoxin & Sterility

Peptide identity by HPLC, endotoxin by LAL and PCR sterility testing, each reported on the Certificate of Analysis.

Batch-Specific COA

A Certificate of Analysis tied to your specific lot is published on our site — real documentation, not a generic sheet.

What every COA documents

  • ✓Compound identity & sequence
  • ✓Measured purity (HPLC %)
  • ✓Endotoxin & sterility results
  • ✓Batch / lot number
  • ✓Analytical test date
  • ✓Supplied form & storage

Current batch documentation

Every published lot COA on file.

Don't take our word for it. Each certificate carries a lab sample code. Enter it on the Accumark Labs verification page to confirm the lab issued that report for that lot, then compare it with the PDF below.
