Finnrick analysis

Oasis Peptides shows its strongest purity-focus evidence in Retatrutide, with Melanotan II also recovering after an earlier purity miss. BPC-157 remains mixed despite cleaner recent results, while CJC-1295 is the clear weak spot; evidence is recent but uneven, with sparse peptide volume and early missing batch IDs.

About Oasis Peptides test results from Finnrick

Oasis Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 peptides and 20 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 Oasis Peptides peptides in this dataset are BPC-157 (4 tests), CJC-1295 (3 tests) and Melanotan II (5 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 20 recent tests.
