- CJC-1295 + Ipamorelin
- GHRH receptor agonist + selective ghrelin receptor agonist
- CJC: 1–2mg/week; Ipa: 200–300mcg 2–3x/day
- CJC: 6–8 days; Ipa: 2 hours
- Sustained IGF-1 elevation, lean mass research
- Gold-standard GH secretagogue pairing. Pulsatile signaling maintains receptor sensitivity better than continuous agonism
- MK-677 (Ibutamoren)
- Orally bioavailable ghrelin mimetic
- 10–25mg once daily (oral)
- 24 hours
- Continuous GH/IGF-1 elevation, appetite stimulation
- Simplest administration but appetite increase (20–30%) complicates deficit research. Best for mass-gaining protocols
- BPC-157
- Angiogenesis promoter, fibroblast migration enhancer
- 250–500mcg 1–2x/day (subQ or IM)
- 4 hours (dosing sustained by local tissue retention)
- Tendon, ligament, and soft tissue repair
- No direct anabolic effect, but reduces injury downtime. Allows higher volume training in research models
- TB-500 (Thymosin Beta-4 fragment)
- Actin-binding protein, cell migration promoter
- Front-load: 2–5mg 2x/week for 4 weeks; Maintenance: 2mg/week
- 7–10 days
- Systemic tissue repair, inflammation modulation
- Slower onset than BPC-157 but broader systemic effects. Use when multiple tissue sites require repair
- IGF-1 LR3
- Reduced IGFBP binding, direct muscle IGF-1 receptor activation
- 40–80mcg/day post-training
- 20–30 hours
- Direct anabolic signaling bypassing GH pathway
- Potent but requires precise dosing. Hypoglycemia risk above 100mcg. Best for subjects with blunted GH response
- Follistatin-344
- Myostatin sequestration, activin receptor pathway inhibition
- 100–300mcg every other day
- 24–48 hours
- Myostatin inhibition in trained models near genetic ceiling
- Only effective in highly trained subjects. Minimal effect in novice or detrained models
