Finnrick analysis · Retatrutide

Bopeptide Biotechnology's Retatrutide rating is held down by a 99.28% purity miss, despite later 99.9% purity results and tight fills. Most COAs lack batch identifiers, so traceability is the main caveat.

Vendor Intelligence Report: Bopeptide Biotechnology

The dossier traces Bopeptide from an offline supplied domain to a newer active site and two Chinese company names connected by branding, without registry proof. It also maps the missing public COA channel, GuideChem personnel trail, and quiet X/web promotion footprint.

About Bopeptide Biotechnology test results from Finnrick

Bopeptide Biotechnology is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 3 peptides and 15 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 Bopeptide Biotechnology peptides in this dataset are GHK-Cu (4 tests), Retatrutide (6 tests) and Tirzepatide (5 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 15 recent tests.
