FSD
Shanghai Fushida Chemical
Also known as DYL, Fushida
FSD shows complete testing coverage with all 6 tracked batches carrying lab certificates, above the site median of 85%. However, 5 of 6 batches have been flagged—all from a community blind test of GLP-1 peptides (Retatrutide and Tirzepatide) where results ranged from 99.76% to 99.94% purity, raising questions about consistency or labeling accuracy that FSD has not publicly addressed. Endotoxin testing failed across all 6 batches, a significant deviation from typical vendor practice. No direct batch-specific complaints have been filed, though one customer raised questions about NAD+ that were never tied to a particular lot.
Written from the batch and test records on this page. Every certificate counted here was commissioned by the vendor — no independent test has been submitted to the site. Updated 2026-10-18.
