Simple Peptide
Simple Peptide built a proper COA lookup (search by product, lot, or accession number), claims US cGMP manufacturing and per-batch third-party testing, has a US phone line and a 30-day guarantee. The hitch: the certificate itself only shows up if you have a real lot or accession number, so I couldn't confirm which lab they use.
Score Breakdown
cGMP + per-batch third-party testing claimed; structured COA lookup exists, but lab/method not surfaced without an exact lot.
COA lookup by Product/Lot/Accession implies real certificates; content not viewed without a lot.
Lot (e.g., N-MEL1105112025) and Accession (ACC-#####) search system, strong traceability infrastructure.
No disclosed changes.
No independent reviews retrieved; not on reptides.
US phone support (877-711-0702), 30-day money-back, FL address.
Claims plausible; cert content gated behind lot lookup.
COA infrastructure observed; certificate content not viewed.
Positive Signals
- +Structured COA lookup by product/lot/accession
- +US-based with phone support and address
- +cGMP and per-batch third-party testing claimed
- +30-day money-back guarantee
Trust Concerns
The lookup tool is a good traceability sign, but the actual COA (lab, method, purity) only appears for a specific lot, so the testing lab is still unconfirmed from the outside. One sample COA would clear this right up.
- !Certificate content (lab name, method, purity) not viewable without an exact lot/accession
- !Testing lab not named on public pages
Researcher Notes
- •Structured COA lookup (product/lot/accession)
- •US-based with phone + address
- •cGMP + per-batch testing claimed
- •Lab/method not surfaced without a lot
- •Request a sample COA to confirm
