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.
Umbrella Labs: A SARMs-first vendor — the homepage leads with MK-2866 and the peptide range is secondary. The measured 4.76mg is 95% of the 5mg label, the lowest fill ratio on a certificate we have opened this month. The certificate is vendor-hosted with no lab-side lookup. The homepage claims Umbrella Labs is 'the only supplier of SARMs & Peptides with third-party purity validation', which is demonstrably untrue — a misleading trust claim. No legal entity name is printed. The 3.0 Trustpilot average is the lowest of any active profile we cover.
