5-Amino-1MQ

Peptides

Mechanism

5-Amino-1MQ is a small molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that catalyzes the transfer of a methyl group from S-adenosylmethionine (SAM) to nicotinamide, generating 1-methylnicotinamide (1-MNA). By inhibiting NNMT, 5-Amino-1MQ increases intracellular NAD+ levels, reduces 1-MNA production, suppresses lipogenesis in adipocytes, and modulates the methionine-homocysteine cycle. In vivo, it significantly reduces body weight, white adipose mass, and adipocyte size through enhanced energy expenditure and altered lipid metabolism.

Standard Dosing

Research indicates 50-150 mg daily via oral administration, typically divided into 1-2 doses.

Timing

Morning dosing preferred. Can be taken with or without food.

Cycle Duration

8-12 week cycles.

Side Effects

  • Mild GI discomfort
  • Headache
  • Diarrhea (uncommon)
  • Nausea at higher doses

Contraindications

  • Pregnancy and breastfeeding
  • Severe hepatic impairment
  • Active cancer (NAD+ modulation concern)

Mechanism

TB-500 is a synthetic fragment of Thymosin Beta-4, a 43-amino acid protein that sequesters G-actin monomers, preventing premature polymerization and facilitating cellular migration and morphological changes essential for wound healing. It upregulates actin to promote cell migration, proliferation, and differentiation of stem/progenitor cells at injury sites. TB-500 also enhances angiogenesis, reduces inflammation, and promotes tissue remodeling through increased re-epithelialization and vascular density.

Standard Dosing

Research indicates 2-2.5 mg administered twice weekly via subcutaneous injection.

Timing

No strict timing requirements. Can be administered at any time of day. Systemic action means injection location is not critical.

Cycle Duration

Loading phase: 4-6 weeks. Total cycle: 8-16 weeks.

Side Effects

  • Temporary lethargy
  • Head rush upon injection
  • Injection site irritation
  • Mild headache

Contraindications

  • Active cancer (angiogenesis concern)
  • Pregnancy and breastfeeding
  • Recent myocardial infarction
