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)

Semaglutide

Pharmaceuticals

Mechanism

Semaglutide is a GLP-1 receptor agonist with 94% structural homology to native GLP-1, modified with amino acid substitutions and a C-18 fatty acid chain that enables albumin binding, extending half-life to approximately 7 days. Centrally, it activates anorexigenic POMC/CART neurons and inhibits orexigenic NPY/AgRP neurons in the arcuate nucleus of the hypothalamus, reducing hunger and increasing satiety. Peripherally, it slows gastric emptying, enhances glucose-dependent insulin secretion from pancreatic beta-cells, and reduces glucagon secretion, providing comprehensive metabolic regulation.

Standard Dosing

Research indicates 0.25 mg weekly SC for 4 weeks, escalating to 0.5 mg, then 1.0 mg, then 1.7 mg, then 2.4 mg weekly (FDA weight management protocol). Oral: 3 mg daily for 30 days, then 7 mg, then 14 mg daily.

Timing

SC injection any time of day, with or without food, on the same day each week. Oral: take on empty stomach with no more than 4 oz water, 30+ minutes before first food/drink/medications.

Cycle Duration

Long-term/continuous use. Weight regain occurs upon discontinuation (67% regain within 1 year in trials).

Side Effects

  • Nausea (44% — most common)
  • Vomiting
  • Diarrhea
  • Constipation
  • Abdominal pain
  • Injection site reactions
  • Headache
  • Fatigue
  • Gallbladder events
  • Acute pancreatitis (rare)
  • Potential lean mass loss

Contraindications

  • Personal/family history of medullary thyroid carcinoma
  • Multiple Endocrine Neoplasia type 2 (MEN2)
  • History of pancreatitis
  • Pregnancy (Category X) and breastfeeding
  • Severe GI disease (gastroparesis)
  • End-stage renal disease
