Finnrick analysis

GrayPep's purity-focused record is built entirely on Tirzepatide, where identity and very high purity results are the clear strength. The evidence is recent but narrow, showing consistent purity rather than a broad trajectory, while fill ranges from materially underfilled to near target and the newest COA lacks a batch identifier.

Vendor Intelligence Report: GrayPep

GrayPep’s site pairs a GrayPep domain with Hgp biotech branding and first-name Telegram/WhatsApp operators instead of a verified legal seller. The report traces the non-resolving HGP domain lead, missing policy pages, and unverified GMP/history claims.

About GrayPep test results from Finnrick

GrayPep is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 1 peptide and 4 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 GrayPep peptides in this dataset are Tirzepatide (4 tests) and Retatrutide (0 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 4 recent tests.
