Finnrick analysis

Crush Research's Purity focus record is concentrated in Retatrutide, where identity and purity look strong with 99.7–99.9% purity results. Evidence is still sparse and prior-smoothed, and the main weakness is fill consistency, including one 15 mg vial measured 21% under label.

Vendor Intelligence Report: Crush Research

A visible founder trail improves accountability, but a preserved Wyoming filing lead resolves to a different LLC and the co-owner remains unnamed. The report also maps redirecting domains, payment rails, shared-address leads, and coupon-code promotion channels.

About Crush Research test results from Finnrick

Crush Research is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 4 peptides and 12 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 Crush Research peptides in this dataset are BPC-157 (2 tests), BPC-157, TB-500 (2 tests) and CJC-IPA (2 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 12 recent tests.
