Onyxresearch is a US-based vendor selling both retail quantities and bulk, with a catalogue of around two dozen peptides. COA coverage is minimal—just one Freedom Diagnostics report for a single peptide out of 26—so transparency into testing depth remains limited. Community feedback leans mixed on product quality (44 mentions, mostly from one source), with positive notes on shipping but a couple of customer service complaints, all drawn from a thin sample that hasn't yet built a clear picture.
