VIP
VIP is a naturally occurring 28-amino acid neuropeptide of the secretin–glucagon superfamily. Studied in research involving VPAC1 and VPAC2 receptor signaling, cytokine balance, and smooth muscle tone.

VIP FAQ
Where do I buy VIP peptide?
Blank Peptides supplies VIP in 10mg vials. It is a 28-amino-acid neuropeptide and goes out lyophilized like the rest of the catalogue, with a certificate of analysis carrying the lot number printed on your label. Ordering involves no prescription and no approval queue. Processing time is within 1 business day, and tracking follows at label creation.
What is VIP peptide?
VIP stands for vasoactive intestinal peptide, a 28-amino-acid neuropeptide first isolated from porcine intestine in 1970. It acts at the VPAC1 and VPAC2 receptors and belongs to the same structural family as secretin and glucagon. Research covers smooth muscle signalling, immune modulation and neuroendocrine pathways in cell culture and animal models.
Is your VIP third-party tested for purity?
Yes, to greater than 99%. In-house HPLC and mass spectrometry establish identity and purity on each lot, and an independent laboratory, Freedom Diagnostics or Horizon Analytical, repeats the analysis. Bacterial endotoxin testing is carried out at batch release. The certificate is specific to the lot number on your vial.
How much bacteriostatic water for VIP 10mg?
1mL, our standard ratio, giving a 10mg/mL solution. Introduce the water gently against the glass wall and swirl rather than shake. At 28 residues VIP is a longer sequence than most of what we sell, so allow a little more time for the cake to clear before deciding anything is wrong.
How should VIP be stored?
Lyophilized and sealed at -20C, protected from light and moisture. Freeze-dried powder tolerates ambient transit. VIP is among the more fragile sequences in the catalogue once in solution, so refrigerate at 2 to 8C, avoid any freeze-thaw cycling, and use the reconstituted vial within a short working window.
How is VIP shipped?
From inside the USA in plain outer packaging with no compound names printed on the box, with a processing time within 1 business day. Vials ship padded against impact. Tracking is emailed at label creation, and damaged glass is replaced once support has photos of the vial and packaging.
VIP vs thymosin alpha-1 for immune research?
Different mechanisms. VIP research runs through VPAC receptor signalling and its effect on immune cell behaviour and smooth muscle. Thymosin alpha-1 research centres on thymic peptides and T cell maturation through toll-like receptor pathways. Both appear in immunomodulation literature but they are not interchangeable in a study design.
Is VIP legal to buy for research?
Nothing federal restricts buying VIP as a laboratory reagent, and we ship it domestically without a prescription. It holds no FDA approval for any indication, is not a drug or supplement, and is not intended for human or veterinary administration. Ordering puts the material in your hands as a qualified researcher, and a research setting is the only place it belongs.
