Finnrick analysis · MOTS-c

Recent MOTS-c evidence is mixed: after several clean identity/purity/fill results, June tests slipped to 99.4% and then 98.7% purity. Fill stayed close, but the downward purity trend and weak customer corroboration drive uncertainty.

Vendor Intelligence Report: Reta-Peptide

Corporate records and marketplace filings point away from the listed U.S. manufacturer story and toward a China-based trader model. The report maps the Retalux/@super_chem linkage, Shopify footprint, COA gaps, and crypto/wire payment rails.

About Reta-Peptide test results from Finnrick

Reta-Peptide is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 15 peptides and 258 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 Reta-Peptide peptides in this dataset are BPC-157 (20 tests), Cagrilintide (4 tests) and CJC-1295 (9 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 200 recent tests. It also includes 1 correction related to this vendor.
