Finnrick analysis · Retatrutide

RR Biohakr Retatrutide is mixed: one March sample missed purity at 99.3% and had no batch identifier. Other samples passed identity with -10% to +4% fills, so the main signal is a possibly isolated purity/documentation concern.

Vendor Intelligence Report: RR Biohakr

RR Biohakr's public trail runs through TikTok Shop, while registry, domain, trademark, and review-platform checks leave the operator hard to anchor. The report also tests a Biohackr Health name-overlap lead and a bounded affiliate sweep without overstating either.

About RR Biohakr test results from Finnrick

RR Biohakr is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 2 peptides and 7 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 RR Biohakr peptides in this dataset are Retatrutide (4 tests), Tirzepatide (3 tests) and Cagrilintide (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 7 recent tests.
