As of October 19, 2026, it publishes lot-matched certificates naming three labs and has 7 independent tests on Finnrick. It is cheap on BPC-157 and GHK-Cu but charges a flat $9.99 to $10 per mg on GLP-class compounds, which is above our index median.
Notice: Pure Peptide Labs products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

How it compares
Pure Peptide Labs discloses more about its testing than many vendors we track. For GLP-class compounds, other vendors are cheaper per mg. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
Pure Peptide Labs does the testing disclosure well: named labs, lot numbers and some independent tests. Its pricing is good on common research peptides but high on GLP-class compounds. Compare those against our index before ordering.
