Finnrick analysis · Tesamorelin

Yimei's Tesamorelin profile is improved but not clean: a 71.61% purity failure in November is followed by four identity/purity/quantity passes. Check the COAs for missing batch IDs and the Mar. 7 99.7% purity result.

Vendor Intelligence Report: Yimei

Corporate records tie the Yimei-named UK layer to a dissolved company while Pepturion’s UK-facing site omits ordinary legal identifiers. The report maps the rebrand trail, Hong Kong contact signal, China-side supplier records, payment recourse gaps, and promo-code network.

About Yimei test results from Finnrick

Yimei is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 12 peptides and 128 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 Yimei peptides in this dataset are CJC-1295 (7 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 128 recent tests.
