VIP 10mg — Research Peptide Canada

Sign in for priceSold out

Vasoactive intestinal peptide is a 28-amino-acid neuropeptide of the secretin/glucagon superfamily, signalling through the VPAC1 and VPAC2 receptors. It is studied for vasodilatory, anti-inflammatory and circadian regulatory activity.

About VIP 10mg

VIP is unusually broad in its distribution, acting as a neurotransmitter in the enteric nervous system, a vasodilator in the vasculature, an immunomodulator on T-cell differentiation and a core signalling molecule in the suprachiasmatic nucleus, where it is essential for maintaining circadian synchrony between neurons. That range means the experimental context determines which receptor and which downstream pathway dominates. Its half-life in circulation is very short, on the order of a minute, which is the practical constraint that shapes most protocol design around it.

Storing and handling VIP 10mg

Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Shipping VIP 10mg within Canada

Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, arriving in two to five business days with a tracking number on every one. Orders over CA$200 ship free; see the shipping page for the dispatch cut-off and transit window.

VIP 10mg questions

Are research peptides like VIP 10mg legal in Canada?

VIP 10mg is supplied here strictly as a reference material for in vitro laboratory research. For laboratory research use only. Not for human or veterinary use. Canadian law turns on what a substance is represented and supplied for, which is why that restriction is on the label, the invoice and every page of this site. The full framework, and what a research-use designation does and does not change, is set out on our legality page.

Is VIP 10mg shipped from within Canada?

Yes. Every VIP 10mg order leaves British Columbia, Canada and travels entirely within the country. Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Transit after dispatch is 2–5 business days Canada-wide, with a tracking number on every parcel, and orders over CA$200 ship free.

Does VIP 10mg come with a certificate of analysis?

Yes — the certificate for the lot in your box, not a representative certificate for a different batch. Every VIP 10mg lot is released against a >99% HPLC specification, and the document carries the lot number, the issuing laboratory and the analytical method. Certificates are not published on this site; if you need another copy, ask us for it by lot number.

How is VIP 10mg supplied and stored?

As a lyophilised powder in a sealed vial, which is the form that survives shipping without a cold chain. Unopened vials are stored away from light and moisture; the storage and handling page covers the laboratory conditions in full. We publish no dosing, reconstitution volumes or administration guidance of any kind.

What fill is VIP 10mg supplied in?

VIP 10mg is supplied in a single 10mg fill, released against a >99% specification.
