- TB-500
- Actin regulation, VEGF upregulation, angiogenesis
- Increases capillary density and mitochondrial enzyme activity. Directly improves oxygen delivery and aerobic capacity
- 2.5mg twice weekly (loading), 2mg weekly (maintenance)
- Best evidence for structural endurance adaptations; effects take 6–8 weeks to manifest but persist beyond cessation
- BPC-157
- Nitric oxide modulation, fibroblast activation, collagen synthesis
- Accelerates tendon and ligament repair, reduces joint inflammation. Indirect endurance benefit through injury prevention
- 250–500mcg daily subcutaneous or oral
- Faster acute recovery but no direct vascular or mitochondrial effects; complements TB-500 in high-volume training
- GHK-Cu
- Copper peptide, collagen remodelling, anti-inflammatory
- Reduces systemic inflammation and oxidative stress post-training
- 1–2mg daily subcutaneous
- Limited endurance-specific research; useful for recovery but not performance enhancement
- Epithalon
- Telomerase activation, circadian regulation
- Theoretical longevity and recovery benefits; no established endurance mechanism
- 5–10mg for 10-day cycles
- Insufficient evidence for athletic use; effects are speculative
