Dihexa

Peptides

Mechanism

Dihexa (N-hexanoic-Tyr-Ile-(6)-aminohexanoic amide) is an orally active, blood-brain barrier-permeable oligopeptide derived from angiotensin IV. It binds hepatocyte growth factor (HGF) with high affinity, inhibiting HGF dimerization and synergistically promoting c-Met receptor phosphorylation and signaling. Activation of HGF/c-Met drives procognitive effects through increased dendritic arborization, spinogenesis, and synaptogenesis via the PI3K/AKT signaling pathway. Research indicates it is approximately 10 million times more potent than BDNF for new synapse formation.

Standard Dosing

Research indicates 10-20 mg daily via oral or sublingual administration.

Timing

Morning dosing preferred. Can be taken with or without food (orally active).

Cycle Duration

2-4 week cycles with equal rest periods. Long-term safety data is extremely limited.

Side Effects

  • Headache
  • Jaw tension
  • Increased emotional sensitivity (anecdotal)
  • Potential for excessive synaptogenesis (theoretical long-term concern)

Contraindications

  • Active cancer (HGF/c-Met pathway promotes tumor growth)
  • Pregnancy and breastfeeding
  • History of cancer

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)
