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)

Melanotan II

Peptides

Mechanism

Melanotan II is a synthetic cyclic analog of alpha-melanocyte-stimulating hormone (alpha-MSH) that non-selectively agonizes melanocortin receptors MC1, MC3, MC4, and MC5. MC1R activation stimulates eumelanin synthesis through tyrosinase upregulation, producing tanning. MC3R activation in the CNS increases libido and produces erectile responses. MC4R activation suppresses appetite. The cyclic structure provides enhanced in vivo stability (half-life 1-2 hours) and increased blood-brain barrier permeability compared to linear alpha-MSH.

Standard Dosing

Research indicates 250-500 mcg daily via subcutaneous injection during loading, reducing to 250 mcg 2-3 times weekly for maintenance.

Timing

Administer 4-6 hours before UV exposure for optimal tanning synergy. Can be taken at any time of day.

Cycle Duration

Loading phase 1-2 weeks, then maintenance as long as desired. Pigmentation fades gradually upon discontinuation.

Side Effects

  • Nausea (common, especially during loading)
  • Facial flushing
  • Spontaneous erections
  • Appetite suppression
  • Darkening of existing moles (monitor closely)
  • Fatigue
  • New nevus formation

Contraindications

  • History of melanoma or atypical moles
  • Active skin cancer
  • Pregnancy and breastfeeding
  • Addison's disease
  • Pheochromocytoma
