Best Peptides for Bone-Density Research
Bone-density research examines peptides that promote osteoblast activity, suppress osteoclasts, and preserve mineral content. This overview ranks by bone-specific evidence.
Follistatin 344
Recovery
4.0/ 5
B+
SS-31 / Elamipretide
Longevity
3.8/ 5
B+
Editor's note
Follistatin offers growth promotion via myostatin inhibition; SS-31 targets mitochondrial bone cell function.
| Criterion | Follistatin 344 | SS-31 / Elamipretide |
|---|---|---|
| Osteoblast stimulation | Via myostatin removal | Via mitochondrial support |
| Bone-specific research | Growing (secondary) | Growing (mitochondrial) |
| Systemic growth effects | Primary (muscle/bone) | Targeted (cell energy) |
| Preclinical bone data | Substantial | Emerging |
