PRN partner
Why Purity is currently listed
Purity Peptides is currently PRN’s active supplier partner because it fits the site’s research-use supplier criteria better than thin “where to buy” listings: COA visibility, testing language, Canadian relevance and a clear affiliate relationship.
Review criteria
| Criterion | PRN review note |
|---|---|
| Batch COAs | Publishes batch-specific certificates of analysis for research compounds. |
| Testing type | PRN looks for HPLC and mass spectrometry documentation where available. |
| Shipping region | Listed for Canada and United States in PRN supplier data. |
| Research-use language | Supplier framing should remain research-only, not human-use or dosing oriented. |
| Affiliate disclosure | PRN discloses the partnership beside commercial calls to action. |
What readers should still verify
Supplier pages can change. Before relying on any supplier for a research project, verify the current batch COA, product identity, testing date, shipping policy, storage expectations and research-use-only documentation.
Affiliate relationship
PRN may earn a commission if readers use the partner link or code. That relationship is disclosed here and on the supplier page. Commercial terms do not override the review criteria.
