VIP vs KPV
VIP sits in immune, while KPV sits in healing & recovery — so despite being mentioned together they are used for different things. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
They aren't really substitutes: VIP sits in Immune while KPV sits in Healing & Recovery. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Route of administration differs — VIP is typically nasal or subq, KPV is typically subq (or oral). That alone changes how convenient each one is to keep up with.
Where they overlap: reduced inflammation.
Reported mainly for VIP: immune balance, mold/cirs support.
Reported mainly for KPV: ibd relief, skin healing.
What VIP is
Vasoactive Intestinal Peptide (VIP) functions as a neuropeptide and exhibits broad biological activity throughout the body. Its primary mechanism of action involves binding to specific G protein-coupled receptors, particularly VPAC1 and VPAC2, which are extensively distributed on various cell types including immune cells, epithelial cells, and neurons. Upon binding, VIP activates adenylate cyclase, leading to an increase in intracellular cyclic AMP (cAMP) levels, which mediates its downstream effects. While VIP has
What KPV is
KPV is a tripeptide fragment derived from the C-terminus of alpha-melanocyte stimulating hormone (alpha-MSH). Research indicates its primary mechanism involves potent anti-inflammatory effects. It is thought to exert its actions, in part, by interacting with melanocortin receptors, particularly MC1R, which are present on various cell types including immune cells and epithelial cells. This interaction can modulate intracellular signaling pathways, such as the inhibition of NF-κB activation, leading to a reduction in
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — VIP and KPV are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between VIP and KPV?
They aren't really substitutes: VIP sits in Immune while KPV sits in Healing & Recovery. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Can you log VIP and KPV in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, VIP or KPV?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
