- This table compares the three primary peptide protocol approaches used in athletic performance optimization, showing mechanism, typical dosing patterns, expected timeline to measurable results, and suitability for different training goals.
- Growth Hormone Secretagogues (MK 677, GHRP-2)
- Amplify endogenous GH pulses via ghrelin receptor activation
- Once daily (MK 677) or 2–3x daily post-training (GHRP-2)
- 8–12 weeks for lean mass gains; 4–6 weeks for recovery improvements
- Hypertrophy-focused athletes, strength athletes in caloric deficits, recovery from soft tissue injuries
- Most versatile class. Directly supports both muscle growth and tissue repair through elevated GH signaling.
- Repair Peptides (BPC-157, TB-500)
- Modulate VEGF expression, accelerate fibroblast migration to injury sites
- Twice daily regardless of training schedule
- 2–4 weeks for pain reduction; 6–8 weeks for structural healing
- Tendinopathies, ligament/tendon injuries, chronic joint inflammation
- Fastest measurable impact on injury recovery. Irreplaceable for athletes managing structural damage.
- Metabolic Optimization Peptides (Tesofensine, SLU PP 332)
- Enhance mitochondrial biogenesis, shift substrate utilization toward fat oxidation
- Once daily, timing varies by compound
- 6–10 weeks for improved aerobic efficiency and body composition
- Endurance athletes, combat sport athletes managing weight cuts, multi-hour training sessions
- Niche application. Most valuable for athletes where energy system efficiency is the primary limiter.
