- Before selecting peptides for performance or recovery applications, understanding the evidence base, dosing precision, and receptor saturation dynamics is essential. Not all peptides marketed to athletes have clinical data supporting their claimed effects.
- GHRP-2
- Ghrelin receptor agonist → GH pulse elevation
- High (multiple RCTs in healthy adults)
- 100–300mcg SC, 2–3x daily
- 90+ min from meals, before sleep
- GH amplification without exogenous GH receptor desensitization
- Ipamorelin
- Selective GHSR-1a agonist → GH release without prolactin/cortisol elevation
- Moderate (Phase 2 trials, limited bodybuilding-specific data)
- 200–300mcg SC, 2–3x daily
- Morning, post-training, pre-sleep
- Clean GH elevation for recovery without hormonal side effects
- IGF-1 LR3
- IGF-1 receptor agonist → direct mTOR activation, reduced IGFBP binding
- Moderate (clinical use in wasting syndromes, no RCTs in athletes)
- 40–80mcg SC daily
- Post-workout or morning
- Amplified protein synthesis independent of endogenous GH/IGF-1 levels
- BPC-157
- VEGF upregulation → angiogenesis, fibroblast migration, collagen synthesis
- Low (animal models only, no human RCTs)
- 250–500mcg SC daily
- Near injury site or systemic
- Accelerated tendon/ligament healing, reduced joint inflammation
- TB-500
- Actin upregulation → cell migration, reduced scarring, inflammation resolution
- Low (animal models, case reports)
- 2–5mg SC, 2x weekly
- Systemic administration
- Soft tissue injury recovery, prevention of adhesion formation
- CJC-1295 (no DAC)
- GHRH analog → amplified endogenous GH release when stacked with GHRP
- Moderate (Phase 1/2 trials in GH deficiency)
- 100mcg SC, 2–3x daily
- Concurrent with GHRP dosing
- Synergistic GH pulse amplification when combined with secretagogues
