Finnrick analysis · Retatrutide

XTP Retatrutide's profile is pulled down by a recent 92.8% purity result after earlier high-purity identity/fill passes. The next read is whether that June batch is an outlier, since several prior tests lacked batch identifiers.

Vendor Intelligence Report: XTP

XTP’s public trail runs through a privacy-protected Lithuanian domain, an unverified Xi’an company name, and a forum handoff after a representative account was banned. The report checks the Janoshik claim, warehouse context, and identity-failure dispute without overstating customs links.

About XTP test results from Finnrick

XTP is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 3 peptides and 18 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 XTP peptides in this dataset are Retatrutide (14 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 18 recent tests.
