Overview

KPV is the final three amino acids of alpha-melanocyte-stimulating hormone. It enters cells through the PepT1 transporter. Research looks at how it dampens NF-kappaB inflammatory signaling in gut epithelial and immune cells.

Mechanism

The last three amino acids of alpha-MSH. It reduces NF-κB inflammatory signaling in gut and skin models.

Research areas

Storage & reconstitution

Supplied as a lyophilized powder; keep sealed, dry and away from light, ideally frozen or refrigerated for long-term holding. Laboratories typically reconstitute with bacteriostatic or sterile water, swirling gently rather than shaking, then hold the solution refrigerated (2–8 °C) and use it within the window set by their own stability protocol.

Recommended starting dose (low and slow)

Starting doseLow end of the studied range: 200 mcg; 250 mcg; 200 mcg.
FrequencyReported schedules: daily; 250mcg-1mg daily; Daily.
ReconstitutionExamples: 5 mg vial + 2 mL bacteriostatic water = 2.5 mg/mL; 10mg vial + 2mL diluent (as listed). storage note: Reconstituted: refrigerate, used within 4 weeks.

Studied higher doses

Studies have used doses up to the amounts below. Higher doses can be dangerous. Whether a person can reach them safely depends on height, weight, activity level, training and pre-existing conditions. We recommend following the lower starting dose above, and contacting SRP with any questions.

Highest amount reported in studiesTop of the studied range: 500 mcg; 1 mg; 500 mcg. These are range tops, not verified ceilings. Reported amounts vary by 2x or more.
