The main concern is a 99.21% purity miss; later MT204 samples recovered to 99.66% and 99.7% with identity passes and modest fill variance. Evidence is clustered in one batch, so batch-to-batch consistency remains uncertain.

About Precision Peptide Co test results from Finnrick

Precision Peptide Co is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 5 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 Precision Peptide Co peptides in this dataset are BPC-157 (5 tests), GHK-Cu (4 tests) and Ipamorelin (4 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.
