Yes — eNOS genetics directly shapes the nitric oxide foundation that vascular sexual response is built on. NOS3 variants determine how much NO your endothelium produces per arousal signal. The Precision Peptide Genetic Test analyzes eNOS variants as part of 14 pathways, 49 peptides, and 150+ genetic insights, answering the question bloodwork alone cannot.

PDE5 pathway support works differently for different people — and genetics is one of the most direct explanations for that variability. The Precision Peptide Genetic Test maps upstream NOS3 and downstream pathway variables as part of 14 pathways, 49 peptides, and 150+ genetic insights, explaining the vascular dimension of differential response.

eNOS — the endothelial nitric oxide synthase enzyme encoded by NOS3 — is the genetic starting point of the vascular cascade that sexual arousal depends on. The Precision Peptide Genetic Test analyzes NOS3 variants as part of 14 pathways, 49 peptides, and 150+ genetic insights, mapping the upstream NO signal before it reaches the PDE5 pathway.
