- CJC-1295 + Ipamorelin
- Restores GH pulsatility via GHRH analog and ghrelin receptor agonism
- 200–300 mcg combined, 5–6 days/week before training or sleep
- 40–60% increase in serum IGF-1 over 8–12 weeks; improved muscle protein synthesis response to training
- Best option for addressing age-related GH decline; synergistic effects require stacking both compounds
- BPC-157
- Promotes angiogenesis and collagen remodeling; accelerates soft tissue repair
- 250–500 mcg daily, split or single dose
- 30–40% faster tendon and ligament healing; allows higher training frequency without overuse injury
- Critical for athletes with chronic joint issues; enables volume increases that drive hypertrophy
- TB-500
- Enhances cell migration and differentiation; reduces systemic inflammation markers
- 2–5 mg twice weekly for loading, then weekly maintenance
- 25–35% reduction in post-training muscle damage markers; faster return to baseline performance
- Most effective when paired with high-volume training blocks; allows same-muscle training every 48 hours
- MK-677 (Ibutamoren)
- Oral ghrelin mimetic; elevates GH and IGF-1 without injection
- 10–25 mg daily, typically before bed
- Sustained IGF-1 elevation; improved sleep quality and recovery markers
- Convenient oral alternative to injectables; less dramatic GH spikes but consistent elevation over 24 hours
