Blank Peptides
reptides B · 5.8Blank's COA page confirms what their homepage was vague about: testing is independent (Freedom Diagnostics), with HPLC purity, mass-spec identity, endotoxin reports, dated batch COAs showing lot, date and method, and per-compound average purity. That clears up the earlier 'is this in-house?' question in their favor. reptides has them B-tier.
Score Breakdown
Independent third-party lab Freedom Diagnostics confirmed; HPLC purity + mass-spec identity + endotoxin.
Dated batch COAs with lot/date/method full reports; per-compound average purity displayed.
Dated reports per compound (e.g., 2026-05-19, 2025-12-23) plus endotoxin reports with IDs (e.g., B-4755764).
US finishing; no disclosed changes.
reptides B-tier (5.8).
14-day money-back guarantee; fast processing.
COAs substantiate claims; 'FDA-registered facility' framing still a minor caveat.
Named lab + dated full reports; corroborated by reptides.
Positive Signals
- +Independent third-party lab (Freedom Diagnostics) confirmed
- +HPLC + MS + endotoxin
- +Dated batch COAs with lot/date/method
- +Per-compound average purity transparency
- +Separate endotoxin reports with IDs
Trust Concerns
The documentation holds up. The one thing to keep straight: 'FDA-registered/inspected' just means the facility is registered, not that any product is FDA-approved, so don't read it as a blessing. Otherwise the named lab, dated batch COAs and separate endotoxin reports are real positives.
- !'FDA-Registered/Inspected' framing describes facility registration, not product approval
Researcher Notes
