- MK 677
- Ghrelin receptor agonist (GHS)
- Growth hormone → IGF-1 → lipolysis & protein synthesis
- 10–25 mg oral, daily
- Best for sustained metabolic optimization and recovery speed. 24-hour GH elevation without pulsatile crashes
- Hexarelin
- GHRP analog (GHS)
- Pituitary GH secretion (acute pulses)
- 100–200 mcg SC, 1–2x daily
- Best for targeted pre-training or pre-sleep GH spikes. Higher amplitude than MK 677 but shorter duration
- Cerebrolysin
- Neurotrophic factor mimetic
- BDNF/NGF → cerebral glucose metabolism & mitochondrial function
- 5–10 mL IV/IM, 10–20 sessions
- Best for cognitive endurance and mental clarity. Clinically proven in stroke recovery, applicable to healthy populations
- Thymalin
- Thymic peptide bioregulator
- T-cell modulation → reduced systemic inflammation
- 10 mg SC, 10-day cycles
- Best for immune-driven fatigue and recovery optimization. Lowers the metabolic cost of baseline immune function
- CJC-1295/Ipamorelin
- GHRH + GHRP combo (GHS)
- Sustained + pulsatile GH release
- 100–200 mcg each SC, nightly
- Best for combining 24-hour baseline GH support with natural pulsatility preservation. Lower desensitization risk
- Dihexa
- HGF receptor agonist
- Synaptogenesis → reduced cognitive effort & ATP cost
- 5–10 mg oral, daily
- Best for learning, memory, and mental processing speed. Synaptogenic potency 1,000x BDNF in preclinical models
