  • The table below outlines the core peptides used in structured anti-aging protocols, their primary mechanisms, clinical dosing ranges from published trials, and the functional role each plays in a comprehensive stack.
  • Thymalin
  • Thymic epithelial cell reactivation; increases naïve T-cell output and restores immune surveillance
  • 5–10mg per week (subcutaneous or intramuscular)
  • 8–12 weeks, followed by 4-week washout
  • First-line choice for immune senescence reversal; consistent biomarker improvements in CD4+/CD8+ ratios and thymic index across multiple trials
  • MK-677 (Ibutamoren)
  • Ghrelin receptor agonist; stimulates endogenous GH and IGF-1 secretion without axis suppression
  • 10–25mg daily (oral)
  • 12–16 weeks, with periodic 2-week breaks to prevent desensitization
  • Most reliable GH secretagogue for lean mass preservation and metabolic support; monitor fasting glucose during extended use
  • Cerebrolysin
  • Neuropeptide delivery; upregulates BDNF, NGF, and CNTF; promotes synaptic formation in hippocampus
  • 5–10ml per session, 2–3 sessions per week
  • 4–8 weeks per cycle, maximum 3 cycles annually
  • Gold standard for cognitive enhancement in age-related decline; effects sustained 8–12 weeks post-cycle in memory consolidation tests
  • Dihexa
  • Hepatocyte growth factor receptor agonist; increases BDNF expression 6–7× baseline in hippocampal neurons
  • 5–10mg daily (varies by formulation)
  • 4–6 weeks, followed by 8-week rest period
  • Potent neuroplasticity agent; effects plateau after 6 weeks, requiring extended breaks to restore receptor sensitivity
  • P21
  • Promotes neurogenesis and dendritic spine formation; modulates hippocampal glutamate signaling
  • 10–30mg per week
  • 6–8 weeks
  • Emerging compound with strong preclinical data; human trials limited but promising for memory enhancement
