Puratek Peptides is a newer US research-peptide supplier (established late 2025) whose standout is COA depth: detailed per-product certificates published openly at /coa/, a 7-panel test scope, and a 99% purity guarantee that refunds you if an independent test comes back under spec. On the samples we reviewed, reported net peptide content actually ran over-label — the right direction.
That public, batch-level testing is exactly what our 40% COA factor rewards most, and a founder-provided Trustpilot history (4.8 across roughly 62 reviews) that we reviewed directly backs it up. Two practical notes before ordering: Puratek is new, so the track record is still accumulating, and payment is peer-to-peer (Zelle / Cash App / Venmo) rather than card — so there's no chargeback protection.
