With Peptide Sciences gone, buyers are scrambling. We've ranked 21 suppliers by quality score, independent testing availability, and product overlap. No paid placements — just data.
Trust scores factor in: COA/third-party testing availability, payment processor stability (credit card vs crypto-only), product catalog breadth, community feedback, and regulatory history. Scores are algorithmically generated — suppliers cannot pay to improve their rank.
