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.
Licensed Peptides: Trustpilot profile REMOVED — and every product page still shows a self-hosted, Trustpilot-styled '4.9 • 847 verified reviews' badge, which costs it the clean-record point. The cart promises a '30-Day Money Back Guarantee' while the Terms say all sales are final. Certificates are vendor-hosted with no lab lookup, and no measured net content was readable. Tirzepatide and retatrutide sold as LP2-T / LP3-R (CAS printed). Premium pricing; our 5% code is the weakest of any partner.

What do Licensed Peptides customers complain about?
Three themes recur in the negative reviews: slower-than-expected shipping despite the stated ~12-hour dispatch, customer service that some buyers describe as dismissive or unresponsive, and pricing that several reviewers consider high for the category. None of these relate to product quality — the criticism is about logistics, support, and cost.
