VIP5 5MG (Vasoactive Intestinal Peptide)
Vasoactive intestinal peptide in the 5 mg freeze-dried fill
VIP5 is PrymaLab’s name for vasoactive intestinal peptide, a 28-residue neuropeptide that acts on the VPAC1 and VPAC2 receptors. This vial is the 5 mg fill of freeze-dried powder, made and tested as its own lot; the 10 mg vial is the main listing. Studies of VIP concern its receptor pharmacology and its roles in nerve, gut and immune function.

Other fills
This is the 5 mg fill. The VIP5 10MG (Vasoactive Intestinal Peptide) page is the main listing for this compound, with the full research summary and every fill side by side. Other fills: 10 mg.
What the research covers
VIP was first isolated from hog intestine as a 28-residue peptide that dilated blood vessels and stimulated breathing1. Its receptors VPAC1 and VPAC2 also bind PACAP with high affinity, so the two peptides overlap in what they can activate, and only PAC1 tells them apart2. The VIP5 10 mg vial page has the full research summary.
The VIP Peptide guide covers the literature in more depth.
How each lot is tested
Every lot is tested in PrymaLab’s own laboratory in Ashland, Kentucky before release: RP-HPLC for purity, LC-MS for identity, Karl Fischer titration for water, LAL for endotoxin and USP <71> for sterility. Published certificates are listed on the results page and can be checked by number and key on the verify page. These are in-house results from PrymaLab Analytical, not an independent test, and the lab is not accredited to ISO 17025. The third-party testing guarantee on this page still applies: if any independent laboratory finds the wrong compound, or less than the stated purity or amount, the order is refunded and the cost of the test is reimbursed.
Frequently asked questions
Is the 5 mg vial the same peptide as the 10 mg?
Yes. Both hold VIP (1-28) amide, CAS 40077-57-4, as freeze-dried powder, and one safety data sheet covers both. The 5 mg fill is a separate lot with its own number and certificate.
When does a 5 mg fill make sense?
When a study uses less peptide per reconstituted vial. A smaller fill leaves less solution waiting at 2 to 8 °C after reconstitution, while the sealed vial is stored the same way as the 10 mg: −20 °C, dry and dark.
