Peptide Supply Co
Peptide Supply Co says every batch is independently third-party tested to 99%+ with COAs you can view, and ships free 2-day. The gap is the usual one: no lab or method named, and I couldn't confirm the COAs are batch-specific.

Trust Concerns
The per-batch testing and public COA claims are fine as far as they go, but with no lab or method named and no confirmed batch-specificity, it's trust-me territory. Ask for a batch-specific COA and the lab's name.
