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.
Ameano Peptides: The homepage advertises a 30-day money-back guarantee while its own FAQ says all sales are final. A live NAD+ batch was listed with 'no COA yet' despite the every-batch claim. No standalone semaglutide or tirzepatide; retatrutide only as a blend.
