A 28-amino-acid neuropeptide with vasodilatory and immunomodulatory activity. The aviptadil formulation reached large registered trials in respiratory failure. Use in chronic inflammatory response syndrome is far less well evidenced. Hypotension is a real risk.

Adding 3 mL of bacteriostatic water to a 10 mg vial gives 3.33 mg/mL. That is the mix every number on this page is worked out from — change the water figure in the calculator and all the draw amounts update.
Published and reported figures for VIP on this protocol run from 100 mcg to 200 mcg, five days a week, stepping up over eight weeks. This site lists each figure with the source it came from rather than giving a single recommended number.
At 3.33 mg/mL, a 100 mcg dose is 3 units on a 1 mL U-100 insulin syringe. One vial at that mix gives about 100 doses.
VIP is graded clinical. Human trial or approved-label dosing has been published for this compound. We grade every compound on this site so you can weigh the numbers accordingly — the full method is on our editorial policy page.
