Finnrick analysis · Retatrutide

Yiwu Beigong Retatrutide evidence is mixed: one 99.14% purity miss interrupts otherwise passing identity/purity results. A later 99.9% purity result helps, but batch IDs are mostly absent and the latest fill was -11%.

Vendor Intelligence Report: Yiwu Beigong

Corporate records tie the Yiwu Beigong contact path to a Huaian Hanyou/Huaian Banting address cluster rather than a clean standalone vendor identity. The report also traces recent web infrastructure, website-scam warnings, a Selena sales trail, and payment/fulfillment complaints.

About Yiwu Beigong test results from Finnrick

Yiwu Beigong is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 1 peptide and 5 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 Yiwu Beigong peptides in this dataset are Retatrutide (5 tests), BPC-157 (0 tests) and Cagrilintide (0 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 5 recent tests.
