What is — VIP
VIP (vasoactive intestinal peptide) is a 28-amino-acid neuropeptide of the secretin/glucagon family, supplied by Peptworks as a lyophilized 10 mg vial for laboratory research use only. It is a wholesale/white-label research reagent for B2B resellers, not a medicine, supplement, cosmetic or medical device, and is not intended for human or animal consumption. Each batch is characterized to >=98% HPLC purity with an independent Certificate of Analysis (HPLC + heavy metals).
In experimental systems, VIP is studied as an endogenous signaling peptide that acts through the class B G-protein-coupled receptors VPAC1 and VPAC2, coupling predominantly to adenylate cyclase and downstream cyclic-AMP/PKA signaling. Preclinical and in-vitro literature explores its role as a smooth-muscle relaxant, a co-transmitter in autonomic and enteric neurons, and a modulator of immune and neuroendocrine signaling. Peptworks makes no claim regarding effects in humans; all mechanistic description refers to published in-vitro and animal research models.
Research
- Circadian biology and suprachiasmatic-nucleus signaling in animal models
- Pulmonary and airway smooth-muscle research in vitro
- Immunomodulation and inflammatory-signaling models
- Enteric and autonomic neurotransmission studies
- Vasodilation and vascular smooth-muscle preclinical research
- Neuroprotection and neuroinflammation models relevant to longevity research
Advantages
- Studied as a smooth-muscle relaxant in preclinical vascular and airway models
- Investigated for anti-inflammatory signaling in in-vitro immune-cell assays
- Used as a reference ligand for VPAC1/VPAC2 receptor pharmacology research
- Examined in circadian-rhythm and neuroendocrine research paradigms
- Explored in cellular models relevant to longevity and tissue-homeostasis research
Safety
- Reported in research literature as a potent vasodilator, causing hypotension and flushing in animal-model studies
- Associated with tachycardia and cardiovascular responses in preclinical vascular models
- Peptide is labile and sensitive to degradation, a documented handling consideration in in-vitro work
- No human safety profile is established or implied; this is a Research Use Only reagent not for consumption
Ideal for
- Academic and industrial laboratories running receptor-pharmacology assays
- Preclinical research groups modeling vascular, pulmonary or immune signaling
- Contract research organizations needing per-batch CoA-verified reference peptide
- Resellers building a white-label longevity-research peptide catalogue
- In-vitro screening programs studying VPAC1/VPAC2 ligands

Frequently asked questions
Where can I buy VIP peptide in bulk in the EU?
Peptworks supplies VIP (vasoactive intestinal peptide, 10 mg lyophilized vials) wholesale from stock already inside the EU, so orders ship intra-community in 3-5 business days with no customs. You can order unbranded bulk vials or white-label vials boxed under your own brand. This is a B2B research-reagent supply for Research Use Only; Peptworks does not sell to end users.
What is the wholesale price per vial for VIP?
VIP pricing is public and per-vial, with combined-volume discounts applied to the whole order: EUR 44.00/vial at 100 units (base), EUR 36.08/vial at 300 units (-18%), EUR 33.00/vial at 500 units (-25%), and EUR 29.92/vial at 1000 units (-32%). The discount is a single tier based on the combined total units across your order, not stacked. Payment is by USDC bank transfer/invoice.
Can I get VIP peptide white-labelled with my own brand?
Yes. Peptworks offers two formats: unbranded bulk vials, or white-label vials labelled with your own brand and boxed. There is a one-time label setup fee of EUR 180 for orders under 100 units, which is free from 100 units onward. The outer box carries the Peptworks label and a unique QR that links to that batch's Certificate of Analysis.
What is the minimum order for VIP?
The minimum order is 10 units (one box) per reference. Vials ship in boxes of 10. Volume pricing begins at the 100-unit tier, so mixing references toward a combined 100, 300, 500 or 1000 units unlocks the corresponding discount on the whole order.
How is the VIP Certificate of Analysis verified?
Every batch ships with an independent Certificate of Analysis covering HPLC purity (>=98%) and heavy metals. The box carries a unique QR code that links directly to that specific batch's CoA, verifiable through Peptworks, so resellers and their customers can confirm identity and purity per lot.
What quality and shipping terms apply to VIP orders?
VIP is supplied as a >=98% HPLC-purity research reagent with per-batch CoA (HPLC + heavy metals). Stock is held inside the EU, so intra-community delivery is typically 3-5 business days with no customs. The full site operates in 10 languages and payment is by USDC (Polygon/Base)/invoice; there is no card checkout. Material is Research Use Only, not for human or animal consumption.
