| Origin of Peptide | Derivative of VIP |
| 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. |
| Cargo Sequence/Structure | None |

| Assay | Radioactive assay, Measurement of E2(Erection) |
| Enhancer | None |
| Properties of enhancer | Not applicable |
| Concentration | Each rat received 30-50 µg Stearyl-VIP in about 10 µl ointment (2 g lubricant [K-Y Vaginal Lubricating Jelly], 10 mg Stearyl-VIP, 1.7 ml nitroglycerin [1 mg/ml] and 130 µl of DMSO). |
