Finnrick analysis · Melanotan II

Repeated sub-99.5% purity results drive this low reliability signal despite passing identity. The newer 99.9% result also came with +19% overfill, so batch continuity and the trend matter more than a clean reset.

About Nuscience Peptides test results from Finnrick

Nuscience Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 10 peptides and 48 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 Nuscience Peptides peptides in this dataset are Melanotan II (7 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 48 recent tests.
