LL-37 vs Adipotide
Side-by-side comparison of key properties, dosing, and research.
- 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.
- Adipotide (FTPP) is a chimeric proapoptotic peptide that selectively targets and destroys blood vessels feeding white adipose tissue. It binds prohibitin on the vasculature of fat tissue, delivering a proapoptotic sequence that induces cell death in fat-specific blood vessels, causing targeted fat tissue regression.
- Half-Life
- Very short (~1–2 hours) in plasma due to protease degradation; topical use bypasses systemic clearance
- Estimated 2-4 hours
- Admin Route
- SubQ, Topical, Intranasal
- Subcutaneous, Intravenous (research)

- Typical Dose
- 100–300 mcg
- Not established for humans; primate studies used 0.1-1 mg/kg
- Frequency
- 2–3x per week
- Daily for 4 weeks (research protocol)
- 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
- Targeted reduction of white adipose tissue
- Promotes fat vasculature apoptosis without systemic toxicity
- Demonstrated significant fat loss in primate studies
- Potential for visceral and subcutaneous fat reduction
- Novel non-hormonal mechanism distinct from GLP-1 agonists
- Explored for obesity and metabolic syndrome
- 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
- Renal toxicity observed in primate studies (transient, dose-dependent)
- Dehydration and electrolyte imbalances in research
- Weight regain upon cessation
- Limited human data; side effect profile largely from animal studies
