Research-context information only. Vasoactive intestinal peptide (VIP) is a research peptide. Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
The buying problem mirrors LL-37: 28-residue length pushes synthesis cost, vendor competition is limited, and per-mg pricing is high.
This guide covers documented per-mg pricing, COA verification, vial size selection, and red flags. For dosing context, see the VIP dosing guide.

How to Verify VIP Quality
What a COA Should Include
Identity Confirmation
Mass spec confirming 3,326 Da for VIP
Sequence verification — 28-residue sequence
C-terminal amidation confirmed
Purity Testing
HPLC purity at 98%+ (challenging at 28 residues — 95-98% more common)
Single dominant peak; truncation byproducts visible as smaller secondary peaks
Niche-format vendor — oral capsule peptides, pre-mixed nasal solutions, and a rare Reta + Cagrilintide combo blend, all 25% off with code thepeptidecatalog.
Most cloudy reconstitutions trace back to one thing — and it isn't the peptide. Sterile, non-pyrogenic, 0.9% benzyl alcohol — formulated for peptide reconstitution, not repackaged from generic stock.

Frequently Asked Questions
Is VIP legal to buy?
Vasoactive intestinal peptide (VIP) is sold as a research peptide labeled 'not for human consumption.' Aviptadil (synthetic VIP) has been studied in COVID-19 and sarcoidosis trials but is not FDA-approved. Purchasing research peptides is legal in most US jurisdictions.
How much does VIP cost per month?
Community subcutaneous protocols use 50-200mcg/day. Monthly mass at 100mcg/day is 3mg. Research-vendor 5mg vials run $80-180 and 10mg vials run $140-300. Monthly cost ranges from $90-300.
Why is VIP priced higher than most peptides?
VIP is a 28-residue peptide — at the upper end of cost-effective synthesis. Limited vendor competition and small market size also push pricing higher. Per-mg pricing is typically $14-30/mg vs $2-8/mg for shorter peptides.
What vial size should I buy?
5mg vials are the most-cited size given the typical low daily doses. 10mg vials require staged reconstitution at most community protocols.
What purity should I look for in VIP?
Third-party HPLC at 98%+ purity, plus mass spec confirming 3,326 Da. VIP is a 28-residue peptide with C-terminal amidation. At 28 residues, truncation byproducts are common synthesis impurities.
Can I buy VIP from a compounding pharmacy?
Limited. Aviptadil is not FDA-approved despite Phase 2 trial work in sarcoidosis and COVID-19. Some specialty pharmacies have offered intranasal or nebulized VIP but the supply chain is restricted. Research vendors are the documented option.
