Test my supplyPrime Peptides' purity-focus record is strongest for Ipamorelin, where identity and 99.5%+ purity held across labs, but that signal is still narrow and batch-concentrated. BPC-157 and GHK-Cu show repeated misses driven by purity drops or large overfills, while CJC-1295 improves on a later batch after an identity failure.
We investigated who actually operates Prime Peptides — corporate records, ownership trails, web infrastructure, and how its lab results break down product by product. Read the full report before you order.

About Prime Peptides test results from Finnrick
Prime Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 peptides and 19 tests, including ratings, observed price signals, recent test dates, and correction history where available.
Finnrick ratings are calculated from published sample data using the selected rating standard. The default standard evaluates purity, dose accuracy, and label quality, then adjusts low-volume results so small sample counts do not appear more certain than the data supports.
The most visible Prime Peptides peptides in this dataset are BPC-157 (6 tests), CJC-1295 (3 tests) and GHK-Cu (5 tests). Use the peptide table above to compare the current Finnrick rating, price per mg, and sample volume for each peptide.
Recent tests and corrections are shown below when available. Samples may be acquired by Finnrick directly or submitted through Finnrick testing programs; the goal is to make safety and supply-chain evidence easier to evaluate than vendor marketing claims alone. This page currently lists 19 recent tests.
