Frequently Asked Questions

What is VIP?
VIP (Vasoactive Intestinal Peptide) is a synthetic 28-amino-acid peptide corresponding to the naturally occurring neuropeptide of the same name, with CAS number 40077-57-4, molecular formula C147H238N44O42S, and a molecular weight of approximately 3,326 g/mol. Pure Health Peptides supplies it as a lyophilized powder strictly for in vitro laboratory research.
What is VIP studied for in research?
In controlled laboratory settings, VIP is studied as an agonist at the VPAC1 and VPAC2 receptors. Research literature reports the peptide's involvement in smooth-muscle relaxation, vasodilation, and immune-signaling pathways in study models. These are research findings; all applications are non-clinical.
How does VIP relate to aviptadil?
Aviptadil is the international non-proprietary name assigned to vasoactive intestinal peptide in pharmaceutical contexts. Pure Health Peptides does not supply a pharmaceutical product. The material listed here is research-grade: it is not manufactured, tested, or released to pharmacopoeial or GMP standards, is not an approved drug, and is not supplied for any clinical or medical use.
What are VIP's chemical specifications, and what size does it come in?
VIP has the molecular formula C147H238N44O42S and a molecular weight of approximately 3,326 g/mol (refer to the lot-specific Certificate of Analysis for the exact value). It is supplied as a lyophilized white powder in 5 mg and 10 mg vials at greater than or equal to 99% purity (HPLC). Store in a cool, dry place away from light and moisture, and consult the Safety Data Sheet before handling.
Where can I buy VIP, and is it third-party tested?
VIP is available from Pure Health Peptides as research-grade material in 5 mg and 10 mg vials at greater than or equal to 99% HPLC-verified purity. Every production lot is third-party tested in the US, with a lot-specific Certificate of Analysis available for verification.
Is VIP intended for human or clinical use?
No. VIP is for research use only and is not intended for human or veterinary use. It has not been evaluated by the FDA and is not a drug, food, cosmetic, or dietary supplement. It is supplied only to qualified research professionals for in vitro laboratory research, and KYC verification is required prior to fulfillment. Any use outside of controlled in vitro research is strictly prohibited.
