Finnrick analysis

EZ Peptides' Purity focus record is narrow and mixed, with all rated evidence on Retatrutide rather than a broader catalog signal. Retatrutide has some passes but repeated purity misses, including a 93.2% result and a newer 99.4% miss, so the recent chronology adds uncertainty despite smoothing from priors.

Vendor Intelligence Report: EZ Peptides

Website footers, a Florida filing, and TikTok operator accounts do not resolve to a clean EZ Peptides channel. The report also traces an ISO accreditation mismatch, coded GLP checkout rails, and a discount network with weak disclosure.

About EZ Peptides test results from Finnrick

EZ Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 2 peptides and 11 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 EZ Peptides peptides in this dataset are Retatrutide (8 tests), Tirzepatide (3 tests) and GHK-Cu (0 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 11 recent tests.
