Overview
Alpha Peptides sells lyophilized research peptides and named blends, plus bacteriostatic water, with a deep growth-hormone bench alongside GLP-class metabolic research, recovery blends, longevity, cognitive, sleep and reproductive-health compounds. It files its Certificates of Analysis by lot on a public COA page, from two named laboratories: Freedom Diagnostics for its 2025 lots and Analytical Formulations, Inc. for its 2026 lots.
Alpha Peptides states that its bulk peptide comes from cGMP-aligned manufacturing partners, and that its standard is a 99.0% purity floor, with lots below it rejected rather than discounted or relabeled.

Testing: Labs & Certificates of Analysis
The certificates on Alpha's COA page (alpha-peptides.com/coas) come from two laboratories. Its 2025 lots carry Freedom Diagnostics reports: purity by HPLC with UV detection, identity by mass spectrometry and net peptide content, each with a search code that resolves on Freedom's own site rather than Alpha's. Its 2026 lots carry Analytical Formulations, Inc. summary reports, three of them served from the laboratory's own storage rather than copied by Alpha; those test by UV/Vis spectrophotometry — identity by a λmax match against a reference standard, a percent-purity figure, a quantitative assay in mg per vial, and combined heavy metals — rather than by HPLC or mass spectrometry.
Prof. Peptide drew three Freedom Diagnostics certificates at random from the COA page and checked each at the laboratory's own document store on October 11, 2026; the panel below lists every certificate's own results. The COA page lists every product with its current certificate and earlier batches kept alongside, each row carrying the lot code the certificate is filed under, and Alpha states that every vial is labeled with its batch number.
