Finnrick analysis · Retatrutide

Repeated early purity misses and a +249% fill result hold Bfflink Retatrutide's purity-focused score back, though recent results improved. Check post-February scored tests: identity and fill pass, with some 99.6-99.7% purities near cutoff.

Vendor Intelligence Report: Bfflink

UK registry checks, predecessor WHOIS records, and archived forum captures trace Bfflink from AMO/BFF branding into a private-link ordering model. A new privacy-protected domain and unverified LTD claim create authentication and recourse gaps.

About Bfflink test results from Finnrick

Bfflink is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 2 peptides and 43 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 Bfflink peptides in this dataset are Retatrutide (23 tests), Tirzepatide (20 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 43 recent tests. It also includes 1 correction related to this vendor.

Finnrick data entry
A data capture error was identified and corrected. The recorded potency was **59.5 mg**, whereas **COA 207430** reports a potency of **95.7 mg**. This discrepancy resulted in an incorrect dosage deviation of **-1%** being recorded instead of the correct value of **+59.5%**. The reported value has been updated to **95.7 mg** in accordance with the COA. As a result of this correction, the calculated score was revised from **10.0** to **6.5**.
