VIP peptide

Reviewed

Short answer

VIP is a natural 28-amino-acid body signal. A trial of synthetic VIP did not establish a treatment benefit. Human physiology and a clinical trial have been studied; product approval needs a separate current check.

This guide explains research. It was not independently medically reviewed, and it does not diagnose, prescribe, or recommend treatment.

Study and product details

What it is

VIP means vasoactive intestinal peptide. It is a natural body signal made from 28 amino acids. It affects blood vessels and other body systems. Aviptadil is synthetic VIP used in specific research studies. A natural body signal and a finished drug product are different things.

Type of peptide: Natural body signal. This describes what the substance is or how it works. It does not show that it is safe, effective, or approved.

What has been studied?

  • Limited: Research is too small or incomplete, or does not directly answer this question.
  • Unclear: There is not enough reliable detail about the product or research to judge.
Did people's health improve?
Limited

A 196-person aviptadil trial in critical COVID-19 respiratory failure missed its prespecified day-60 primary endpoint. Other trial results do not prove a treatment benefit.

What body changes did studies in people measure?
Limited

A 12-person healthy-volunteer study measured a short vascular response and delayed headache during and after VIP infusion.

What do we know about risks in people?
Limited

The cited human studies cover specific research material and routes. They do not establish the safety of other VIP products or long-term use.

Do we know what the product contains and how well it was made?
Unclear

The checked FDA records identify a substance and two orphan designations. They do not establish approval, quality, or equivalence of a finished product.

Products with the same ingredient can differ.

The ingredient name does not tell you everything about a product. Check its other ingredients, its form, how it enters the body, and the use and people covered by the research or approval.

Approved products

None identified in the United States.

Approved or reviewed uses

No approved use.

What studies found

Findings

In 12 healthy volunteers, a two-hour VIP infusion widened a head artery and increased mild delayed headache. This measured a short body response, not a health benefit. A randomized trial studied intravenous aviptadil in 196 people with critical COVID-19 respiratory failure. Its main result was whether people were alive and free from respiratory failure at day 60. That primary result did not reach statistical significance. Some other results favored aviptadil, but they do not make the main result a success.

What remains unknown

These studies do not show that VIP treats COVID-19, lung disease, gut disease, or aging. The trial did not test other routes or products. The FDA records checked here identify aviptadil and two orphan designations. Both designation records say the named orphan indication was not FDA approved. Those records do not establish the approval status of every possible product or use. They also do not show that an online or compounded item matches the trial material.

Which products do these findings apply to?

VIP is a natural body signal. Aviptadil is synthetic VIP studied as a defined intravenous research treatment. An FDA substance record or orphan designation is not approval of a finished drug. Neither record shows that a compounded or online product matches the trial material.

Body changes and lab tests

“VIP is a natural peptide made from 28 amino acids.”

Supported with scope

The discovery report identifies a 28-residue intestinal peptide. This identity fact does not establish a human treatment.

Body changes and lab tests

“VIP infusion changed blood-vessel and headache measures in healthy people.”

Supported with scope

A study of 12 healthy volunteers measured a short vascular response and delayed headache after a specified infusion. It did not test a disease treatment.

Health results

“Aviptadil proved effective for critical COVID-19 respiratory failure.”

Not established

The 196-person randomized trial did not meet its prespecified day-60 primary endpoint. Secondary and subgroup results cannot make the primary endpoint significant.

What this answer is based on
Health results from a study with randomly assigned groups
Limits of this answer
Intravenous aviptadil in the 2022 trial; no inference about another VIP product.

Approval and status

“An FDA aviptadil substance record or orphan designation is drug approval.”

Misleading

A substance record identifies a substance. The two checked FDA orphan records state that the named orphan indications were not approved. Neither record approves a finished product.

What this answer is based on
Official record or product label
Limits of this answer
The exact FDA records checked September 12, 2026; this is not a complete product-level approval search.

Comparing products

“A compounded or online VIP product matches the aviptadil trial material.”

Not established

The cited trial studied defined intravenous research material. The checked FDA records do not establish the identity, quality, route, or equivalence of another product.

What this answer is based on
No reliable studies showing this health result in people
Limits of this answer
Online and compounded products compared with the 2022 trial material.
