Vasoactive Intestinal Peptide (VIP) is a 28 amino acid neuropeptide found throughout the central and peripheral nervous systems, gastrointestinal tract, and immune tissue. One of the most broadly distributed and functionally diverse regulatory peptides in human physiology. iLab Pharma’s formulation supplies 10mg as a lyophilized vial, preserving peptide structural integrity and potency across storage conditions until reconstitution, essential for a peptide with documented sensitivity to aqueous degradation that limits its stability in solution at ambient temperature.
VIP’s receptor biology underpins its exceptionally broad research profile. It acts primarily through VPAC1 and VPAC2 G protein coupled receptors distributed across an unusually wide range of tissue types: smooth muscle, immune cells, neurons, epithelial cells, and endocrine tissue among them. This receptor distribution produces a correspondingly diverse pharmacological activity profile: vasodilation and bronchodilation through smooth muscle relaxation, neurotransmitter and neuromodulator activity in both central and enteric nervous systems, potent immunomodulatory effects including anti inflammatory cytokine regulation and T regulatory cell promotion, and trophic effects on intestinal epithelial tissue. The breadth of VIP’s documented biological activity has made it one of the most studied regulatory peptides across multiple research disciplines simultaneously. Spanning pulmonary, gastrointestinal, immunological, and neurological research contexts within a single compound.
VIP’s immunomodulatory research profile is particularly active in contemporary literature. Its documented ability to shift immune responses toward anti inflammatory and tolerogenic phenotypes through VPAC receptor mediated suppression of pro inflammatory cytokine production including TNF alpha, IL 6, and IL 12. This has generated significant research interest in autoimmune, inflammatory, and sepsis research contexts. This anti inflammatory mechanism operates through pathways distinct from peptide immunomodulators like Thymosin Alpha-1 and Thymalin, making VIP a complementary rather than redundant research tool in CSD’s immune focused peptide range for studies examining different arms of peptide mediated immune regulation.
iLab Pharma formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range.
