Test my supplyPeptidology's purity-focus record is strongest on GHK-Cu, PT-141, and Retatrutide, where identity, purity, and fill signals generally hold. The weak side is dispersed but meaningful: BPC-157 has repeated purity misses, Ipamorelin worsened on a newer purity result, and CJC-IPA carries an overfill caveat, with evidence often batch-narrow.
We investigated who actually operates Peptidology — corporate records, ownership trails, web infrastructure, and how its lab results break down product by product. Read the full report before you order.

About Peptidology test results from Finnrick
Peptidology is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 7 peptides and 21 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 Peptidology peptides in this dataset are BPC-157 (3 tests), CJC-IPA (2 tests) and GHK-Cu (6 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 21 recent tests. It also includes 2 corrections related to this vendor.
