Adipotide vs PE-22-28
Side-by-side comparison of key properties, dosing, and research.
- Summary
- 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.
- PE-22-28 is a synthetic analog of spadin derived from sortilin, designed to block TREK-1 potassium channels with rapid-onset antidepressant and neurogenic effects. It shows fast-acting depression relief (within 24 hours) and promotes hippocampal neurogenesis.
- Half-Life
- Estimated 2-4 hours
- Relatively short; CNS effects may persist due to neurogenic mechanisms
- Admin Route
- Subcutaneous, Intravenous (research)
- SubQ, Intranasal

- Typical Dose
- Not established for humans; primate studies used 0.1-1 mg/kg
- 200–400 mcg
- Frequency
- Daily for 4 weeks (research protocol)
- Once daily
- Key Benefits
- 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
- Rapid-onset antidepressant effects (within 24 hours)
- Promotes hippocampal neurogenesis
- Improves cognitive performance and memory
- Reduces anxiety and depressive behavior
- Novel mechanism — does not act on serotonin/dopamine/GABA receptors directly
- May help treatment-resistant depression
- Neuroprotective effects
- Side Effects
- 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
- Generally well tolerated in animal models
- Limited human data available
- Possible mild headache or transient mood changes at initiation
- Injection site reactions (SC)
