What VIP is

Vasoactive Intestinal Peptide (VIP) functions as a neuropeptide and exhibits broad biological activity throughout the body. Its primary mechanism of action involves binding to specific G protein-coupled receptors, particularly VPAC1 and VPAC2, which are extensively distributed on various cell types including immune cells, epithelial cells, and neurons. Upon binding, VIP activates adenylate cyclase, leading to an increase in intracellular cyclic AMP (cAMP) levels, which mediates its downstream effects. While VIP has a relatively short circulating half-life, typically measured in minutes, its signaling cascade plays a significant role in modulating immune responses, promoting vasodilation, influencing smooth muscle relaxation, and exerting neuroprotective effects.

In research settings, VIP is being explored for its potential immunomodulatory properties, with observed effects on cytokine profiles and T-cell differentiation. Researchers investigating VIP for its practical use may observe changes over a period of days to weeks, depending on the specific research parameters and individual responses. While there are no established "stacks" for research peptides, some studies may investigate VIP alongside compounds that support general cellular health or neuroimmune pathways. Typical research cycles can vary significantly, often spanning several weeks to months with careful titration and monitoring. Notable considerations in research include its potent vasodilatory effects and the need for meticulous observation of physiological parameters, reinforcing that VIP is for research use only and this information does not constitute medical advice.

Storage & handling

LYOPHILIZED (unopened): store at 2-8°C (fridge) or -20°C (freezer) long-term. Protect from light.

AFTER RECONSTITUTION: refrigerate 2-8°C. Do NOT freeze. Discard after 30 days OR if the solution becomes cloudy, discolored, or contains particulates.

What people track

Because individual responses vary so much, the useful thing is your own record: what you logged and when, how much is left in the vial, and how your chosen metrics move over the weeks. Peptide Wizard keeps all of that in one place, alongside a 3D reference vial for VIP.
