Oath Research
Oath posts proper batch COAs, each with a batch number, accession number, test date, purity and a full PDF, from named independent labs ILS and Freedom Diagnostics, and they keep a test history per volume. This is among the best paperwork on the list. The catch is small: they rebranded from Oath Peptides without explaining why, and there isn't much independent community history yet.
Score Breakdown
Named independent labs (ILS, Freedom Diagnostics); HPLC, mass-spec and endotoxin testing shown on batch COAs.
Structured batch COA: product, batch/lot, accession #, test date, purity, full PDF.
Batch A1226 + accession #2606170165, with per-volume test history (5mg: 6 tests, 10mg: 7 tests).
Test history over time visible; no disclosed supplier changes.
Not on reptides; Trustpilot mostly positive, but an independent analysis on PeptideScore reportedly flagged elevated lead in a sampled product.
Free shipping over $250; same-day fulfillment; AZ address.
Batch COAs back the purity claims, but a reported lead-contamination finding would sit awkwardly against the 'purest peptides, period' line.
Named labs + full PDFs + per-batch history; verified via authenticated session.
Positive Signals
- +Named third-party labs (ILS, Freedom Diagnostics)
- +Batch + accession COA with full PDF
- +Per-volume test history
- +HPLC/MS/endotoxin
Trust Concerns
The COAs themselves are great. Two things hold it back: the rebrand from Oath Peptides isn't explained, and an independent analysis on PeptideScore reportedly found elevated lead in a sampled product, which is a heavy-metals red flag worth taking seriously even if their own COAs read clean. If you're using this, I'd get an independent heavy-metals panel on your batch.
- !An independent analysis reported on PeptideScore reportedly flagged elevated lead in a sampled Oath product, which would contradict the purity claims (single source, worth independent confirmation)
- !Rebrand from Oath Peptides unexplained
- !Independent community reputation not yet established
Researcher Notes
- •Named labs ILS + Freedom Diagnostics
- •Batch + accession COA with full PDF
- •Reported lead-contamination finding on PeptideScore (single source, get your own heavy-metals test)
- •Rebranded from Oath Peptides (unexplained)
- •Independent community track record still thin
