Finnrick analysis · Tesamorelin

Zenith Jove Peptide ZJ's purity-focused record is strongest in GHK-Cu and Retatrutide, where repeated identity and high-purity results offset fill outliers and traceability gaps. Tirzepatide and TB-500 are more uneven, with purity misses, a failed-identity vial on Tirzepatide, and recent rebound signals tempered by batch-ID gaps.

About Zenith Jove Peptide ZJ test results from Finnrick

Zenith Jove Peptide ZJ is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 9 peptides and 89 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 Zenith Jove Peptide ZJ peptides in this dataset are BPC-157 (10 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 89 recent tests.
