Fit Aminos has 77 official-matched public COAs. The set covers identity and purity throughout, measured content in 75 files, and endotoxin in 34; it does not establish sterility, heavy-metal, or fentanyl screening. Thirty-nine current product-strength rows have exact product matches.
The Trustpilot record, card checkout, US shipping terms, and verified 10% code support an 8.5/10 overall review. The unmatched source file is held privately, and five current rows remain without exact COA matches.
01
Fit Aminos COA tests and coverage
Reviewed October 4, 2026: Fit’s redesigned archive lists 85 batch entries across 45 product cards, representing 78 distinct merchant PDFs after duplicate/shared links are reconciled. Seventy-six are byte-identical to the retained public archive. One newly retained historical Tesamorelin 10 mg report, accession 2510270101/lot TM100037 issued October 30, 2025, matches Freedom Diagnostics’ complete official PDF byte for byte and measures 12.35 mg at 99.861% purity. The public library now contains 77 complete one-page lab-confirmed reports; 75 include measured content and 34 include LAL endotoxin results. The reports do not show sterility, heavy-metals or fentanyl panels. The previously held BPC-157/TB-500 file with literal code fita2505140016 still returns 404 and remains excluded; it does not increase public certificate or verified counts. Historical reports remain separate from current exact stock controls.
02
Fit Aminos exact product COAs
The current catalog has 44 in-stock product-strength rows, with exact COA matches on 39. The five unmatched rows are BPC-157 20 mg, GLOW Protocol 70 mg, Glutathione 1500 mg, IGF-1 LR3 1 mg, and Sermorelin 10 mg. A 10 mg BPC-157 report cannot support a 20 mg row, and a different GLOW blend does not support the current 70 mg formula. The library retains historical reports without attaching them to unrelated products.
