Why Koi Peptides leads this list
Koi Peptides scores 72/100 overall: testing 82, transparency 86, track record 40. Koi Research Labs LLC (brand Koi Peptides), stated founded 2022 and 'synthesized and lyophilized in the United States' at an unnamed partner facility; ranked #1 in LearnMuscles' 2026 list. Site claims in-house HPLC/LC-MS plus blind retest at an unnamed ISO/IEC 17025 lab with HPLC, LC-MS, ICP-MS metals, LAL endotoxin and (About page) sterility; the public COA PDF for BPC-157 is from Freedom Diagnostics and shows only HPLC-UV purity, LC-MS identity and net content, so endotoxin/sterility are marked unknown. The BPC-157 product URL now 301-redirects to kylopeptides.com (Kylo Labs LLC, same Sheridan WY registered address, Trustpilot 4.3 from 13 reviews) which names Janoshik, Freedom Diagnostics and Vanguard Laboratory; the relationship is undisclosed on both sites. No 5mg BPC-157 list price verified on koipeptides.com (homepage shows $0.00; Kylo shows 5mg at $19.98 member price only). No FDA warning letter found (search hits are for the unrelated Koi CBD, LLC).
