KPV

Peptides

Mechanism

KPV (Lysine-Proline-Valine) is a C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (alpha-MSH) that inhibits NF-kB signaling through a non-melanocortin receptor-mediated mechanism. It is transported intracellularly via the PepT1 transporter, where it stabilizes IkB-alpha and suppresses nuclear translocation of p65RelA by competing with importin-beta at the armadillo domain 7 and 8 binding site. It also reduces MAPK inflammatory signaling and IL-8 secretion in intestinal epithelial cells.

Standard Dosing

Research indicates 200-500 mcg daily via subcutaneous injection, or 500 mcg-1 mg orally for gut-targeted inflammation.

Timing

Oral dosing on empty stomach for gut-targeted effects. No strict timing for subcutaneous.

Cycle Duration

4-12 weeks. Oral protocols for gut inflammation may extend longer under supervision.

Side Effects

  • Mild injection site irritation
  • Transient skin flushing
  • Mild GI discomfort with oral dosing

Contraindications

  • Pregnancy and breastfeeding
  • Known hypersensitivity to alpha-MSH derivatives

MOTS-c

Peptides

Mechanism

MOTS-c is a 16-amino acid mitochondrial-derived peptide encoded by the 12S rRNA gene of the mitochondrial genome. It primarily acts through the folate-AICAR-AMPK pathway: by regulating the folate cycle and de novo purine biosynthesis, it increases AICAR accumulation, which phosphorylates and activates AMPK. This enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and mimics exercise-mediated physiological responses. Skeletal muscle MOTS-c levels increase 11.9-fold in response to acute exercise in young men.

Standard Dosing

Research indicates 5-10 mg administered 3-5 times per week via subcutaneous injection.

Timing

Morning administration preferred. Can be dosed pre-workout for enhanced exercise performance.

Cycle Duration

8-16 week cycles.

Side Effects

  • Injection site reactions
  • Mild fatigue post-injection
  • Transient flushing
  • Muscle soreness (exercise-mimetic effect)

Contraindications

  • Pregnancy and breastfeeding
  • Type 1 diabetes (insulin sensitivity changes require monitoring)
  • Not FDA-approved
  • Limited human safety data
  • Active cancer (metabolic pathway activation)
