Finnrick analysis · Retatrutide

Superior Peptides Retatrutide's main caveat is traceability: later clean purity/fill tests lack batch identifiers. Identity passed throughout, purity stayed 99.7-99.9%, fills ran +6% to +9%, and limited depth keeps the signal smoothed.

About Superior Peptides test results from Finnrick

Superior Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 1 peptide and 4 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 Superior Peptides peptides in this dataset are Retatrutide (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 4 recent tests.
