"Pharmaceutical grade" has a precise meaning in regulated manufacturing: material produced under GMP conditions meeting pharmacopeial monograph specifications. In research-chemical marketing it means, legally, nothing at all.
No research-peptide vendor selling outside the drug supply chain is distributing pharmaceutical-grade product in the regulated sense, regardless of actual quality. Some sell excellent material; the phrase is simply not evidence of it. Our scoring system credits verifiable signals — batch COAs, named manufacturers, independent test performance — and ignores grade claims entirely.
