Finnrick analysis · Retatrutide

Top Peptide retatrutide has a low-concern purity-focus profile, with repeated identity/purity passes and a steady trend. Caveats: fill swings from +22% to -16% and many missing batch IDs; newer COAs add IDs and endotoxin/metals checks.

Vendor Intelligence Report: Top Peptide

Corporate records, a separate operator email domain, and a public COA tie the storefront to a broader YH/YiHang trail while stopping short of common-ownership proof. The report also documents exposed site internals, COA gaps, lookalike domains, and direct-contact payment limits.

About Top Peptide test results from Finnrick

Top Peptide is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 6 peptides and 48 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 Top Peptide peptides in this dataset are BPC-157 (4 tests), GHK-Cu (5 tests) and Retatrutide (13 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 48 recent tests.
