LL-37 vs 5-Amino-1MQ

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

Immune SupportRecovery & Repair
LL-37
Fat Loss & Metabolic
5-Amino-1MQ
Summary
LL-37 is the only known human cathelicidin antimicrobial peptide. It kills bacteria, fungi, and viruses by disrupting their membranes, while simultaneously modulating immune responses. Used for antimicrobial protection, immune priming, and wound healing.
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.
Half-Life
Very short (~1–2 hours) in plasma due to protease degradation; topical use bypasses systemic clearance
Estimated 4–8 hours
Admin Route
SubQ, Topical, Intranasal
Oral
Research
Typical Dose
100–300 mcg
50–100 mg
Frequency
2–3x per week
Once to twice daily
Key Benefits
  • Broad-spectrum antimicrobial (bacteria, fungi, viruses)
  • Promotes wound healing and angiogenesis
  • Immune system modulation — enhances innate immunity
  • Reduces LPS-mediated endotoxemia
  • Anti-biofilm activity against resistant organisms
  • Promotes tissue regeneration and keratinocyte migration
  • May protect against sepsis
  • 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
  • Injection site redness and irritation
  • Mild inflammatory response at injection site
  • Potential pro-inflammatory at high doses
  • Rare: fever or flu-like symptoms at initiation
  • Generally well-tolerated in available studies
  • Mild GI discomfort (rare)
  • Limited long-term human data
