Finnrick analysis · PT-141

HK Peptides' PT-141 score is held back by a March quantity failure: a 10 mg vial tested at 17.2 mg (+72%) despite passing identity and 99.7% purity. Earlier tests were mostly strong, but missing batch IDs limit traceability.

Vendor Intelligence Report: HK Peptides

Corporate records and homepage evidence point past the Hong Kong branding to a mainland operating trail and a separate manufacturing-facing domain with verification friction. The report maps the HKMS PEP/HPT adjacency, copycat domains, crypto payment rails, and forum impersonation signals.

About HK Peptides test results from Finnrick

HK Peptides is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 13 peptides and 460 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 HK Peptides peptides in this dataset are BPC-157 (22 tests) and Melanotan II (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 200 recent tests.
