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.
Direct Peptides: The certificate says 'searchable via horizonanalytical.com', but the lab's Verify COA form did nothing when we submitted the report number on 19 Sep 2026 — no request was sent — and the form's own example lot number uses this vendor's 'DPS-' prefix. The lab's domain was registered in October 2025 and its site prints no address. We found no shared infrastructure between vendor and lab, so we are not calling it captive, but the lab-side verification does not work today. Trustpilot profile REMOVED. No legal entity name printed; the address is a numbered mailbox suite. GLP products are sold as 'GLP-1 SM', 'GLP-2 TZ' and 'GLP-3 RT' without the compound stated, so they are excluded from our price index.
