Finnrick analysis · Tesamorelin

PurePeptides' purity-focus record is strongest on Tirzepatide, where identity, purity, and fill stay inside limits despite earlier overfills and later COAs lacking batch IDs. Retatrutide is mostly clean but drifting on fill with a recent large overfill, while Ipamorelin is the weak spot with repeated low purity, short fills, and thin batch breadth.

About PurePeptides test results from Finnrick

PurePeptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 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 PurePeptides peptides in this dataset are CJC-1295 (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 21 recent tests.
