Overview
The cognitive and neuro-research peptides here are studied for neurotrophic and neuromodulatory signaling, largely in preclinical and early clinical literature. Evidence depth varies widely across the group, so this guide states the strength of the published record for each compound plainly rather than implying a uniform effect.
Vasoactive intestinal peptide, a 28-amino-acid neuropeptide studied for neuroimmune and vasodilatory signaling.
Evidence at a glance: Preclinical (animal) evidence
The cited evidence here is preclinical animal-model work, with limited or no human-trial data. Read the research profile accordingly.

Researched mechanism
Agonist at VPAC receptors, studied for anti-inflammatory and vasodilatory signaling.
Described as a mechanism characterized in the literature, not an effect you should expect from use.
What the published research shows
Neuroimmune modulation characterized in preclinical models.
Honest note on evidence: Very short solution stability; handle per research protocol. Evidence is largely preclinical.
Every citation states its study type and population, so preclinical data is never presented as human-efficacy evidence.
How it compares
| Versus | Attribute | Note |
|---|---|---|
| KPV | Focus | Both appear in anti-inflammatory research by distinct mechanisms. |
Reconstitution
Concentration math only: adding bacteriostatic water to the vial gives the resulting mg/mL shown below. This is not usage guidance.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 5 mg | 2 mL | 2.5 mg/mL |
Storage & stability
| State | Temperature | Duration |
|---|---|---|
| Lyophilized (unopened) | -20°C | 24 months |
| Reconstituted | 2–8°C | up to 1 week |
Common questions
Why the short storage window?+
VIP degrades quickly in solution; the storage table reflects that. Keep lyophilized until use.
