Why Licensed Peptides leads this list
Licensed Peptides scores 81/100 overall: testing 100, transparency 94, track record 27. Boca Raton, FL vendor selling vials, 30 ml atomized solutions, capsules and blends; several products carry coded names (LP3-R, LP2-T) recorded here as listed. Publishes a per-lot COA library (mostly JPG scans) naming Vanguard Laboratory and Ethos Analytics, plus separate endotoxin and residual-solvent libraries; sterility and mass-spec are claimed on marketing pages but the COA index lists HPLC only. No 5 mg BPC-157 price could be confirmed because the product page shows conflicting figures; shop grid lists 'From $53.99'. Trustpilot profile has been removed; Finnrick shows 4 tests (2 pass / 2 fail).
