| Nature of Peptide/Cargo | A key penile neurotransmitter, induces erection after local injection in man. Significantly increased sexual function as measured by copulatory activity and penile reflexes(erections) in testosterone-treated, castrated rats. |
| Mechanism | VIP stimulates contractility in the heart, causes vasodilation, increases glycogenolysis, lowers arterial blood pressure and relaxes the smooth muscle of trachea, stomach and gall bladder. |
