Finnrick analysis · Semaglutide

Peptide Crafters' Semaglutide has a low-concern purity-focused profile, with passed identity checks, purity ≥99.532%, and fills +1% to +15%. The caveat is scope: evidence is aging and clustered around PC-J-S5 and PC-J-S15.

About Peptide Crafters test results from Finnrick

Peptide Crafters is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 7 peptides and 41 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 Peptide Crafters peptides in this dataset are Semaglutide (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 41 recent tests.
