Caveats
Purgo Labs: Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Polaris Peptides: The storefront hides every price behind 'Login to see price', and by 6 Sep the About, Contact and policy pages had gone behind a members-only wall too — a reader cannot verify anything without an account. No laboratory named, no certificate library found. Two live pages state different return windows (60 vs 45 days). The independent testing aggregator Finnrick records repeated BPC-157 purity failures for this vendor. 34 reviews.
