Finnrick analysis · Semaglutide

Purely Peptides shows its strongest purity-focused evidence on Tirzepatide, while Retatrutide is more uneven. The record is recent but small, with same-batch Retatrutide split between sub-threshold and strong purity, fill within tolerance, and a later non-classifiable high-purity result leaving uncertainty.

About Purely Peptides test results from Finnrick

Purely Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 5 peptides and 8 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 Purely Peptides peptides in this dataset are Retatrutide (3 tests) and Tirzepatide (2 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 8 recent tests.
