Finnrick analysis

Royal Peptides' strongest purity-focus evidence is Tirzepatide, with steady recent passing identity, purity, and quantity results, while Semaglutide is mostly strong but capped by a latest purity miss. Retatrutide is more volatile, with repeated sub-99.5% purity misses and a severe short-fill; the record is current but batch IDs are often absent.

About Royal Peptides test results from Finnrick

Royal Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 3 peptides and 34 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 Royal Peptides peptides in this dataset are Retatrutide (15 tests), Semaglutide (8 tests) and Tirzepatide (11 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 34 recent tests.
