What is VIP?
VIP (vasoactive intestinal peptide) is a 28-amino-acid neuropeptide first isolated from pig intestine in 1970 by Sami Said and Viktor Mutt. It belongs to the glucagon/secretin family and is made by nerve cells throughout the body. It acts on the receptors VPAC1 and VPAC2 and is studied for its roles in widening blood vessels, relaxing smooth muscle, gut secretion, immune signalling and the body clock.

Available sizes: 5mg, 6mg and 10mg
VIP is offered in three vial sizes: 5mg, 6mg and 10mg. All contain the same peptide. The figure is the total amount of peptide in the vial, supplied as a dry (lyophilised) powder; it is not a concentration, so a larger vial is not “stronger”, it simply holds more material.
