Finnrick analysis · GHK-Cu

Zhengzhou Lan Yun's GHK-Cu profile is tempered by fill and traceability caveats despite clean purity/identity results. One vial was right at the -35% quantity limit, and later COAs include missing batch identifiers.

Vendor Intelligence Report: Zhengzhou Lan Yun Cosmetic Trading

Corporate filings and web-history records split Lanyun’s age story: an older mainland entity sits behind a recent English storefront. The report also maps a parallel Zhengzhou peptide site, mismatched regional contacts, and a shipping-complaint trail.

About Zhengzhou Lan Yun Cosmetic Trading test results from Finnrick

Zhengzhou Lan Yun Cosmetic Trading is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 6 peptides and 41 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 Zhengzhou Lan Yun Cosmetic Trading peptides in this dataset are CJC-1295 (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 41 recent tests.
