Finnrick analysis · PT-141

Wuhan Wansheng PT-141 has a mixed reliability signal: identity passed, but one vial was -48% underfilled and the newest measured lot missed purity at 99.46%. Missing batch IDs on both failures make the record look volatile rather than clean

About Wuhan Wansheng Biotechnology test results from Finnrick

Wuhan Wansheng Biotechnology is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 12 peptides and 261 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 Wuhan Wansheng Biotechnology peptides in this dataset are BPC-157 (20 tests), Cagrilintide (14 tests) and CJC-1295 (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 200 recent tests. It also includes 1 correction related to this vendor.

Lab correction
These were remade and reanalyzed by Lab G. They traced the discrepancy to a likely human error during preparation.
