DNSP-11
THE DOPAMINE PROTECTOR
Dopamine Neuron Stimulating Peptide-11
DNSP-11 is derived from a protein called GDNF (glial cell line-derived neurotrophic factor) that protects dopamine-producing neurons. It helps these neurons survive, grow, and function better. That makes it promising for Parkinson's disease and age-related dopamine decline. Unlike full GDNF, this small peptide can be delivered nasally.

Market evidence
DNSP-11 product testing and COAs
We found no certificates from the DNSP-11 vendors we track. Based on the certificates our crawler found; vendors may publish more than we index. Research on this page describes the molecule. Vendor certificates concern particular market samples or batches; they do not change the research evidence or establish clinical safety, sterility, or suitability for use.
