Test my supplyZLZ Peptide's purity-focus record is broad and recent, led by Retatrutide, Tirzepatide, and GHK-Cu but still marked by purity, fill, or identity outliers. Results are dispersed: Tesamorelin, BPC-157, TB-500, and NAD+ show repeated purity or quantity misses, while spotty batch IDs limit traceability despite some later improvement.
Corporate and B2B records trace ZLZ’s storefront to a Hunan chemical-intermediate operator with BMK/PMK precursor listings. The report also maps altered-COA allegations, alias-led sales channels, irreversible payment rails, and lookalike-domain risk.

About ZLZ Peptide test results from Finnrick
ZLZ Peptide is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 14 peptides and 312 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 ZLZ Peptide peptides in this dataset are Retatrutide (117 tests) and CJC-1295 (5 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 200 recent tests.
