Test my supplyM-Peptides' purity-focus record is strongest in Tirzepatide, where recent identity, purity, and quantity results improved after earlier 99.16% and 97.06% purity misses. Retatrutide is more dispersed, with repeated sub-99.5% purity failures and a -39% fill result, though later rows are cleaner and batch documentation is uneven.
The full report traces a bracelet-themed WooCommerce order portal, two near-lookalike domains, and a stale contact trail that creates impersonation risk. It also maps Elsa’s public footprint, warehouse/regulatory exposure, and Janoshik-only recourse.

About M-Peptides test results from Finnrick
M-Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 2 peptides and 23 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 M-Peptides peptides in this dataset are Retatrutide (9 tests) and Tirzepatide (14 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 23 recent tests. It also includes 1 correction related to this vendor.
