Finnrick analysis · MOTS-c

Guangzhou Aoyu's purity-focus record is strongest in Retatrutide's earlier high-purity identity-pass results, but the catalog is uneven and recently weaker. Tirzepatide is volatile with repeated identity failures and a severe fill miss, while Tesamorelin and MOTS-c have only failing evidence; batch gaps limit confidence despite recent coverage.

Vendor Intelligence Report: Guangzhou Aoyu

Corporate records put the peptide storefront on a platform-only GlobalSources profile while older Aoyu listings sell unrelated goods. The report maps the identity stack, manufacturer-claim conflicts, missing credential trail, and clean-but-limited promotion sweep.

About Guangzhou Aoyu test results from Finnrick

Guangzhou Aoyu is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 peptides and 24 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 Guangzhou Aoyu peptides in this dataset are MOTS-c (2 tests), Retatrutide (6 tests) and Tesamorelin (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 24 recent tests.
