Overview

Vasoactive Intestinal Peptide (VIP) is a naturally occurring signaling peptide with roles in immune regulation, vasodilation, and circadian function. It is used in some functional-medicine protocols, particularly for Chronic Inflammatory Response Syndrome (CIRS).

Vasoactive Intestinal Peptide (VIP) is a naturally occurring signaling peptide with wide-ranging roles: immune regulation, vasodilation and control of pulmonary artery pressure, and even circadian rhythm. It binds VPAC receptors to exert broad anti-inflammatory and immunomodulatory effects, which is the basis for its use in certain functional-medicine protocols.

Its best-known off-label application is in Chronic Inflammatory Response Syndrome (CIRS), often as an intranasal spray, popularized by Ritchie Shoemaker. That use is not backed by large controlled trials, and because VIP is a potent vasodilator it can lower blood pressure. Separately, approved VIP-based drugs exist for unrelated indications, showing the underlying biology is real even where the CIRS protocols are not formally validated.

Mechanism of Action

Binds VPAC receptors to exert anti-inflammatory and immunomodulatory effects, regulate pulmonary artery pressure, and influence circadian and neuroendocrine signaling.

Use Cases

✓Chronic Inflammatory Response Syndrome (CIRS)
✓Immune regulation
✓Inflammation and vascular tone

Research Summary

VIP biology is well studied; intranasal use in CIRS protocols is popularized by Ritchie Shoemaker but not supported by large controlled trials. Approved VIP-based drugs exist for other indications.

Explain It Like I'm 5 Years Old

VIP is a messenger your body already makes that helps calm inflammation, relax blood vessels, and keep your daily rhythms in order. Some people use a nose-spray version to try to settle down long-running, whole-body inflammation. Because it relaxes blood vessels, it can also lower blood pressure, so it has to be used carefully.

How the Gym Bros Are Using It

A niche recovery-and-inflammation tool rather than a performance peptide, mostly known in the CIRS and biohacking world where people use it intranasally to calm chronic, systemic inflammation. The evidence for that use is thin and it can drop your blood pressure, so it is firmly a use-with-caution, know-what-you-are-doing compound — not a mainstream gym staple.
