KPV (Lys-Pro-Val) is a naturally occurring tripeptide derived from alpha-MSH that retains powerful anti-inflammatory action — inhibiting NF-kB and MAPK signaling at nanomolar concentrations — without causing tanning effects. For a full breakdown of the research behind each effect, see our KPV benefits guide. This is not medical advice.

Oral route (preferred for gut inflammation): 500 mcg-1 mg daily on empty stomach, 30 minutes before food. KPV is one of the few peptides with demonstrated oral bioactivity via PepT1 transport.
For complementary anti-inflammatory peptides, see our BPC-157 dosing guide and LL-37 dosing guide.
Cycling Details
Start at 200 mcg daily (oral or SC) during Week 1 to assess tolerance, then increase to 500 mcg. KPV is generally very well-tolerated given its natural origin as a tripeptide fragment. The 5-on/2-off weekly pattern with 8-week cycles accounts for limited long-term human data.
For active gut inflammation, some protocols use higher oral doses (up to 1 mg). Oral dosing is preferred for intestinal targets because PepT1 expression is actually upregulated in inflamed gut tissue — creating a self-targeting mechanism.
Routes of Administration

Oral (preferred for gut health): 500 mcg-1 mg daily on empty stomach. PepT1 transporter actively imports KPV into intestinal epithelial cells. Sublingual (200-500 mcg held under tongue for 60 seconds) is also viable.
Subcutaneous (systemic effects): Standard injection into abdominal fat. Volume typically 0.1-0.2 mL. For systemic anti-inflammatory effects beyond the gut, skin inflammation, etc.

Math: 10,000 mcg / 2 mL = 5,000 mcg/mL. 500 mcg / 5,000 = 0.1 mL = 10 units. Swirl gently, refrigerate, use within 28 days.
For step-by-step reconstitution instructions, see the BPC-157 reconstitution guide — same technique applies to all lyophilized peptides.
Where These Numbers Come From
KPV has robust preclinical evidence, primarily from inflammatory bowel disease models.
Nanomolar KPV concentrations inhibit NF-kB activation and MAP kinase inflammatory signaling, reducing pro-inflammatory cytokines. Oral KPV reduced DSS- and TNBS-induced colitis severity in mice via PepT1-mediated uptake (Dalmasso et al., 2008). KPV showed significant anti-inflammatory effects partially independent of MC1R melanocortin receptor signaling (Kannengiesser et al., 2008).
KPV reduced peritonitis inflammation comparable to full alpha-MSH, confirming that the C-terminal tripeptide retains full anti-inflammatory potency (Getting et al., 2003). A comprehensive review established KPV and related alpha-MSH fragments as a new class of anti-inflammatory agents (Brzoska et al., 2007).
KPV's oral activity is explained by PepT1 transport (upregulated during inflammation), its small tripeptide size (resistant to complete proteolysis), and immune cell uptake enabling direct inflammatory modulation.

Both KPV and BPC-157 can be taken orally. Take KPV on empty stomach; other peptides can follow 15-30 minutes later.
Side Effects & Safety
- Mild nausea — oral route, usually first few days only
- Minor injection site irritation — SC route, transient
- Mild headache — infrequent
- No tanning — does not significantly activate MC1R unlike full alpha-MSH
- Appetite changes — uncommon
- Pregnancy/breastfeeding — no safety data; avoid
- Active immunosuppression — anti-inflammatory effects may compound with immunosuppressive drugs
- Melanoma caution — while KPV lacks significant MC1R activity, exercise caution with any alpha-MSH-derived peptide
Frequently Asked Questions
What is the standard KPV dose?
500 mcg daily — orally on an empty stomach for gut effects, or subcutaneously for systemic effects. 5 days on / 2 days off, cycled 8 weeks on / 8 weeks off.
Can KPV be taken orally?
Yes — KPV is one of the few peptides with proven oral bioactivity. PepT1 transporter actively imports it into intestinal cells, and uptake is actually enhanced in inflamed tissue.
How long does KPV take to work?
Gut inflammation improvements often within 1-2 weeks. Systemic anti-inflammatory effects may take 2-4 weeks. See the KPV results timeline for a full week-by-week breakdown.
Does KPV cause skin tanning?
No. Its effects work through PepT1 transport and NF-kB inhibition rather than melanocortin receptor signaling.
Can KPV be stacked with BPC-157?
Yes — this is the most popular KPV stack. KPV provides NF-kB/MAPK inhibition while BPC-157 promotes mucosal healing. Complementary mechanisms for comprehensive gut repair.
