Finnrick analysis

Pura Peptides shows its clearest purity-focus signal in improving Retatrutide, with Semaglutide clean but supported by only one report. The catalog is dispersed: Tirzepatide has later clean batches but one extreme purity/fill miss, while TB-500 and Tesamorelin sit on sparse mixed evidence despite recent testing.

About Pura Peptides test results from Finnrick

Pura Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 7 peptides and 27 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 Pura Peptides peptides in this dataset are GHK-Cu (2 tests), Ipamorelin (2 tests) and Retatrutide (10 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 27 recent tests.
