VIP (5mg)

Table of Contents

  • Quickstart Highlights

VIP (5mg) refers to Vasoactive Intestinal Peptide, a naturally occurring neuropeptide and signaling molecule studied for its role in immune modulation, anti-inflammatory activity, and cellular communication. VIP interacts with multiple receptor systems (VPAC1 and VPAC2), and has been researched for its potential effects on respiratory function, inflammation balance, and neurological signaling.

This guide outlines a general reconstitution and subcutaneous research use format commonly used in peptide studies.

  • Reconstitute: Add 1.0–2.0 mL bacteriostatic water → 2.5–5 mg/mL concentration
  • Typical research range: 100–500 mcg per dose (varies by protocol context)
  • Easy measuring: At 5 mg/mL, 1 unit = 0.01 mL = 50 mcg on a U-100 insulin syringe
  • Storage: Lyophilized: store at −20 °C; after reconstitution, refrigerate at 2–8 °C and use within 2–4 weeks
  • Protocol Overview

Concise summary of general research use patterns.

  • Goal: Explore immune regulation, anti-inflammatory signaling, and neuroendocrine balance
  • Schedule: Typically used in repeated low-dose cycles in research settings
  • Dose Range: 100–500 mcg per administration, depending on protocol design
  • Dosing Protocol

General research-oriented approach for the 5 mg vial format.

  • Start: 100 mcg to assess tolerance in a research context
  • Target: 200–500 mcg per administration based on study protocol
  • Frequency: 1–2 times per day, depending on experimental design
  • Vial Duration: One 5 mg vial may last several days to weeks, depending on dosing strategy
  • Timing: Often spaced consistently (morning/evening) in structured protocols
  • Mechanism of Action

Vasoactive Intestinal Peptide (VIP) is a 28-amino-acid neuropeptide that functions as both a neurotransmitter and immunomodulatory signaling molecule. It binds primarily to VPAC1 and VPAC2 receptors, activating adenylate cyclase and increasing intracellular cyclic AMP (cAMP).

Through these pathways, VIP is involved in regulating smooth muscle relaxation, vasodilation, immune cell activity, and inflammatory cytokine production. Research suggests it may help shift immune response balance toward anti-inflammatory signaling while also playing roles in pulmonary function, gut-brain axis communication, and neuroprotection.

  • Potential Benefits & Side Effects

Findings based on preclinical and investigational research.
