Finnrick analysis · Retatrutide

FSD's Retatrutide shows a low-concern purity-focus profile, with repeat identity/purity/quantity passes and fills only +1% to +7%. Earlier records lacked batch IDs; recent COAs add them, but limited evidence keeps prior smoothing.

Vendor Intelligence Report: FSD

Registry and domain checks fail to validate the Shanghai manufacturer story behind FSD's chat-based storefront. The report maps the Revolt/Telegram/payment rails and follows a lilac-cap source-chain trail through QST and JEEP contamination records.

About FSD test results from Finnrick

FSD is a peptide vendor tracked in Finnrick's independent testing dataset. This page compiles batch-level results across 5 peptides and 19 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 FSD peptides in this dataset are BPC-157 (2 tests), GHK-Cu (4 tests) and Retatrutide (7 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 19 recent tests.
