  • MK 677 (Ibutamoren)
  • Ghrelin receptor agonist. Stimulates pulsatile GH and IGF-1 release
  • Increases pharyngeal muscle tone and cross-sectional area through IGF-1-mediated protein synthesis
  • 1 pilot RCT (n=18) showed 3.2-point AHI reduction and 11% muscle CSA increase at 12 weeks
  • Plausible adjunct for mild OSA. Mechanism is sound, but evidence base is preliminary and improvements are modest
  • Thymalin
  • Thymic peptide. Modulates immune function and reduces systemic inflammation
  • May reduce chronic inflammation from intermittent hypoxia, supporting vascular and metabolic health
  • No direct OSA trials. Evidence limited to immune regulation and anti-inflammatory effects in aging populations
  • Speculative for OSA. Inflammation is a downstream effect, not a cause of airway collapse
  • CJC-1295/Ipamorelin
  • GHRH analog + ghrelin mimetic. Sustained GH elevation without cortisol spike
  • Supports deep sleep architecture and muscle recovery pathways similar to MK 677
  • No published OSA trials. Sleep quality improvements documented in healthy adults and elderly populations
  • Indirect benefit possible through sleep architecture. No evidence for AHI reduction
  • Dihexa
  • BDNF (brain-derived neurotrophic factor) amplifier. Enhances synaptic plasticity
  • May improve central nervous system regulation of upper airway muscle tone during REM sleep
  • Preclinical only. No human OSA trials exist
  • Highly speculative. Central sleep apnea mechanism is distinct from obstructive OSA
  • BPC-157
  • Synthetic pentadecapeptide. Promotes tissue repair and angiogenesis
  • Could theoretically support pharyngeal tissue healing after chronic trauma from airway collapse
  • No OSA-specific trials. Wound healing and mucosal repair documented in GI and musculoskeletal contexts
  • No direct relevance. Tissue repair doesn't address mechanical obstruction
