Editor's note
Follistatin-344 focuses on muscle hypertrophy; TB-500 on tissue repair and healing.
| Criterion | Follistatin 344 | TB-500 |
|---|---|---|
| Mechanism | Myostatin inhibition | Tissue repair, angiogenesis |
| Muscle hypertrophy focus | Direct growth stimulus | Indirect, recovery-based |
| Tissue healing breadth | Limited | Broad (cardiac, corneal, wound) |
| Research evidence depth | Growing | Moderate |
| WADA status | Prohibited (S4) | Prohibited (S2) |
