Finnrick analysis · TB-500

Lipeptides TB-500 is pulled down by three purity misses before a recent borderline pass. Identity held across tests and fill stayed within tolerance, but the 99.5% purity/+14% fill result is only one clean point.

Vendor Intelligence Report: Lipeptides

Corporate identity runs through hosted COAs, a new Chinese-registered domain, and copied clinic copy rather than a verified registry filing. The report maps the WhatsApp/Telegram agent network, sister-brand signals, payment rails, and fee-demand complaints.

About Lipeptides test results from Finnrick

Lipeptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 6 peptides and 56 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 Lipeptides peptides in this dataset are Retatrutide (28 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 56 recent tests.
