Finnrick analysis · NAD+

ZePeptide's stronger purity-focused signals are GHK-Cu and Tirzepatide, where many lots clear identity and purity but batch traceability is uneven. The record is dispersed rather than steady, with Retatrutide hurt by recent identity and fill failures and Wolverine weak on sparse identity/purity evidence.

Vendor Intelligence Report: ZePeptide

Corporate records, backdated web content, and a shared analytics tag trace ZePeptide from a suspended storefront into a wider domain network. The report follows the payment rails, COA-mismatch claims, and a hyphenated site using another Chinese company’s identity.

About ZePeptide test results from Finnrick

ZePeptide is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 11 peptides and 102 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 ZePeptide peptides in this dataset are BPC-157 (11 tests), GHK-Cu (11 tests) and Ipamorelin (3 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 102 recent tests. It also includes 2 corrections related to this vendor.

Finnrick data entry
During data capture from photographs of sample **9gsfxvk**, the crimp color was incorrectly recorded as **Golden** instead of **Silver**. Verification against the corresponding Certificate of Analysis (COA) confirmed that the correct crimp color is **Silver**. The record has been updated to reflect the information provided in the COA.
