Test my supplyMaddox Research's Purity focus record is narrow and centered on Retatrutide, where recent June tests showed recovery after a severe May identity, purity, and fill failure. Evidence is still uneven: one later Retatrutide vial was underfilled at 15.5 mg versus 20 mg and lacked a batch ID, so confidence is tempered by sparse volume.
Corporate records tie Maddox to a Virginia LLC with a residential-address signal, while a personal payment handle points toward an operator the public site does not name. The report also maps shared web infrastructure, broken legal pages, and promotion-scan gaps.

About Maddox Research test results from Finnrick
Maddox Research is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 1 peptide and 5 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 Maddox Research peptides in this dataset are Retatrutide (5 tests), GHK-Cu (0 tests) and Tirzepatide (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 5 recent tests.
