Shanghai Leader Peptide Biotechnology's purity-focus record is strongest in GHK-Cu and Tirzepatide, with BPC-157 also clean but thinner. Retatrutide and Tesamorelin drive most concern through identity/purity misses and large fill deviations; recent results look better, though batch IDs are uneven and the record is dispersed.

About Shanghai Leader Peptide Biotechnology test results from Finnrick

Shanghai Leader Peptide Biotechnology is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 8 peptides and 82 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 Leader Peptide Biotechnology peptides in this dataset are BPC-157 (4 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 82 recent tests.
