Finnrick analysis

Nanjing Xiyuxun Technology XYX's purity-focus record is strongest on GHK-Cu, where identity and purity clear the bar, though the newer sample is less clean and underfilled. Retatrutide also clears identity and purity, but sparse recent evidence, missing batch IDs, and repeated under-label fills temper confidence.

Vendor Intelligence Report: Nanjing Xiyuxun Technology XYX

Platform records describe XYX as a Made-in-China trader, while its TÜV badge verifies supplier identity rather than GMP. The report maps an XCE/PGB-adjacent supply trail, a Jackdilen sales persona, copied reviews, and disguise-shipping catalog signals.

About Nanjing Xiyuxun Technology XYX test results from Finnrick

Nanjing Xiyuxun Technology XYX is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 2 peptides and 4 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 Nanjing Xiyuxun Technology XYX peptides in this dataset are GHK-Cu (2 tests), Retatrutide (2 tests) and BPC-157 (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 4 recent tests.
