Onyx Biolabs ships from the US and sells both retail and bulk peptides, with no minimum order beyond a single vial. The catalogue spans around two dozen products, though COA coverage is sparse — a few vendor-hosted reports on just a couple of peptides. Community feedback on product quality is mixed across multiple sources, while customer service and shipping experiences lean positive, though those signals come from narrower commentary. The overall anecdotal picture remains thin, with most reviews drawn from individual discussion threads rather than sustained conversation.
