VIP 10mg Peptide

VIP is unusually broad in its distribution, acting as a neurotransmitter in the enteric nervous system, a vasodilator in the vasculature, an immunomodulator on T-cell differentiation and a core signalling molecule in the suprachiasmatic nucleus, where it is essential for maintaining circadian synchrony between neurons. That range means the experimental context determines which receptor and which downstream pathway dominates. Its half-life in circulation is very short, on the order of a minute, which is the practical constraint that shapes most protocol design around it.
