Test my supplyBatch-ID gaps and a small late-2025 COA cluster are key caveats for Zen Peptides' GHK-Cu despite clean purity/fill results. Records show identity passes, 99.95% purity, and overfills up to +18%, with little price/review corroboration.
We investigated who actually operates Zen 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 Zen Peptides test results from Finnrick
Zen Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 7 peptides and 35 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 Zen Peptides peptides in this dataset are BPC-157 (3 tests), GHK-Cu (4 tests) and Ipamorelin (3 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 35 recent tests.
