Test my supplyZhuoyue Biotechnology's purity-focus record is strongest in GHK-Cu and Retatrutide, where identity and high-purity results mostly hold together. Tirzepatide is more dispersed with past identity, purity, and overfill misses despite cleaner recent tests, while TB-500 is the clear weak spot; batch documentation gaps keep confidence limited.
A website-disclosed Wyoming LLC, privacy-masked domain records, and a China-side registry signal do not resolve to a clear operating laboratory. The report also maps a shared WhatsApp trail into unrelated gray-market selling and self-issued COAs with unsupported regulatory language.

About Zhuoyue Biotechnology test results from Finnrick
Zhuoyue Biotechnology is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 peptides and 39 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 Zhuoyue Biotechnology peptides in this dataset are GHK-Cu (5 tests), Retatrutide (14 tests) and TB-500 (3 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 39 recent tests. It also includes 1 correction related to this vendor.
