Why PurePep Exists
Here's what we found after vetting dozens of peptide vendors.
Today we track three COA-verified vendors — Live Alpha Labs, BluGen, and Halo — and refresh pricing and documentation status every month.
When we started comparing research peptide vendors in 2024, the landscape was a mess. Some published COAs that didn't match batch numbers. Others required crypto-only checkout. A few disappeared entirely after the FDA enforcement wave in early 2025.
We built PurePep Vital because we couldn't find one place that just told us: which vendors have real documentation, which take credit cards, and which actually carry the compound we needed. So we built it ourselves.
