Test my supplyHangzhou Mandy Biotechnology's GHK-Cu record is mostly recent high-purity identity passes, but a 98.9% purity miss, uneven fills (+28% to -18%), and batch-ID gaps keep the signal mixed.
Corporate records support a real Hangzhou biotech entity, but domain history and archived pages point to a later peptide pivot. A Seychelles B2B trail tied to the site markets precursor chemicals, while channel and payment rails leave the seller hard to pin down.

About Hangzhou Mandy Biotechnology test results from Finnrick
Hangzhou Mandy Biotechnology is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 peptides and 38 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 Hangzhou Mandy Biotechnology peptides in this dataset are BPC-157 (5 tests), GHK-Cu (6 tests) and Retatrutide (14 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 38 recent tests.
