Identity

PubChem CID 53314964 computed 3D conformer Space-filling 3D model of VIP, carbon grey, nitrogen blue, oxygen red
Built from the SMILES on this record — the atoms, bonds and stereochemistry are exact. The shape is one computed low-energy pose, not a measured structure: a flexible peptide in solution has no single conformation. The skeletal formula below claims connectivity and nothing more, which is what we actually know.

Classified as

Subcutaneousroute
This is the route the reconstitution arithmetic assumes. Mass divided by diluent volume gives concentration, dose divided by concentration gives volume, and volume in mL multiplied by 100 gives units on a U-100 barrel: 5 mg in 2 mL is 2.5 mg/mL, and 0.25 mg comes out at 0.1 mL, which is 10 units.
Intranasalroute
A nasal device delivers a fixed volume per spray, so concentration rather than syringe volume sets the amount per spray, and a mass figure on a record is not usable until you know how many actuations it was divided across.
Intravenousroute
A large share of the pharmacokinetic numbers attached to peptide records, half-life in particular, come from intravenous studies and often from animals. Those numbers describe an intravenous curve and do not transfer unchanged to a depot under the skin.
