Finnrick analysis · Retatrutide

Shanghai Wibson's Retatrutide score is held back by a 99.3% purity miss and a severe -50% fill result, not by identity failures. Since then, results have steadied at 99.8-99.9% purity with single-digit fill deviations and better batch IDs.

Vendor Intelligence Report: Shanghai Wibson Biotechnology WBS

WHOIS, Wayback, and B2B records cut against WBS’s manufacturer/history claims, while the official domain was parked during the field run. Forum sales trails show Gmail-based personas using UK numbers, a WhatsApp data-loss event, and unresolved US-fulfillment ownership.

About Shanghai Wibson Biotechnology WBS test results from Finnrick

Shanghai Wibson Biotechnology WBS is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 8 peptides and 60 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 Shanghai Wibson Biotechnology WBS peptides in this dataset are BPC-157 (6 tests), Cagrilintide (3 tests) and GHK-Cu (4 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 60 recent tests.
