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.
NeuroLabs Research: Every page shows a self-hosted 'Rated 4.9, based on 574 reviews' badge; the actual Trustpilot profile is 4.1 across 31 reviews. Footer 'Contact' and 'Map' links resolve to an unrelated staging hostname. The BPC-157 page is titled 10mg and priced as 10mg while its description says 5mg. No legal entity name. Pre-order items are sold as in-stock. GLP products sold as NL-2 TZ / NL-3 RT with no stated identity.
