Finnrick analysis · Retatrutide

Shanghai ERP's Retatrutide evidence shows early volatility, including a 0 mg identity failure and severe underfills. Recent results form a sustained pass streak, but batch IDs remain uneven.

Vendor Intelligence Report: Shanghai ERP peptide Biotechnology

ERP’s public footprint splits across WordPress, BeikeShop, and a Louise wholesale subdomain, with placeholder policies and mismatched contacts. The report traces Genesis-branded vials, crypto payment rails, a New Hampshire fulfillment clue, and a documented endotoxin dispute.

About Shanghai ERP peptide Biotechnology test results from Finnrick

Shanghai ERP peptide Biotechnology is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 14 peptides and 149 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 ERP peptide Biotechnology peptides in this dataset are BPC-157 (10 tests), Cagrilintide (3 tests) and GHK-Cu (12 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 149 recent tests.
