Alpha-GPC vs 5-Amino-1MQ

Side-by-side comparison of key properties, dosing, and research.

Cognitive Enhancement
Alpha-GPC
Fat Loss & Metabolic
5-Amino-1MQ
Summary
Alpha-GPC is the most bioavailable form of choline, readily crossing the blood-brain barrier to rapidly increase acetylcholine levels. It enhances cognitive performance, supports GH secretion, and is used as an essential complement to many nootropic peptides (especially those that increase acetylcholine demand like Noopept and Dihexa).
5-Amino-1MQ is a small-molecule NNMT (Nicotinamide N-methyltransferase) inhibitor that raises intracellular NAD+ levels and promotes fat burning. It is notable for targeting adipose tissue directly, reducing fat cell size and number while increasing metabolic rate.

Key Benefits
  • Rapidly raises brain acetylcholine levels
  • Enhances memory formation and recall
  • Prevents headaches from nootropic peptides (choline donor)
  • Stimulates growth hormone secretion (modest)
  • Improves attention and processing speed
  • Neuroprotective in Alzheimer's and cognitive decline
  • Approved in Europe for Alzheimer's therapy
  • Enhances power output in athletes (pre-workout)
  • Raises intracellular NAD+ levels
  • Directly targets adipose tissue for fat reduction
  • Reduces fat cell size and differentiation
  • Increases basal metabolic rate
  • SIRT1 activation for metabolic regulation
  • No stimulant cardiovascular side effects
  • Synergistic with intermittent fasting and caloric restriction
  • May have anti-aging metabolic benefits
Side Effects
  • Headache (paradoxically, from excess acetylcholine at very high doses)
  • Nausea at doses > 1200 mg
  • Dizziness
  • Fatigue at high doses
  • +1 more
  • Generally well-tolerated in available studies
  • Mild GI discomfort (rare)
  • Limited long-term human data
