Test my supplyYidan Biotech's Retatrutide rating is held back by a March 2026 98.01% purity miss, not fill problems. Later tests cleared the 99.5% purity bar with identity passes and -5% to -8% fills, but the evidence still rests on a small batch set.
Chinese corporate records tie Yidanbio.com to a named Shanghai company, while look-alike biotech/pharma entities are ruled out. The report follows a Bestway policy artifact, +852 sales routing and off-platform Sunny accounts without treating them as proved ownership links.

About Yidan Biotech test results from Finnrick
Yidan Biotech 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 Yidan Biotech peptides in this dataset are 5-Amino-1MQ (3 tests), GHK-Cu (3 tests) and Retatrutide (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 20 recent tests.
