Finnrick analysis · Semaglutide

Risynth Bio's Semaglutide record is pulled down by an early 99.125% purity miss, while later identity, purity, and quantity results recovered with small fill deviations. The key read is whether that recovery holds across newer batches.

About Risynth Bio test results from Finnrick

Risynth Bio is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 5 peptides and 18 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 Risynth Bio peptides in this dataset are BPC-157 (3 tests), Ipamorelin (3 tests) and 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 18 recent tests.
