- The most important concept in understanding peptides for erectile dysfunction is the central versus peripheral mechanism distinction. PDE5 inhibitors (Viagra, Cialis) work peripherally — they enhance blood flow to erectile tissue AFTER arousal has been initiated by the brain. Peptides for erectile dysfunction work centrally — they activate the brain pathways that INITIATE arousal, desire, and the cascade of signals that produce erection. This means peptides for erectile dysfunction can address desire-related dysfunction that PDE5 inhibitors cannot.
