GDF-11 for Muscle Gain
TGF-beta family ligand controversially linked to age-reversal via parabiosis studies.
Why GDF-11 for muscle gain?
GDF-11 (Growth Differentiation Factor 11) is a TGF-beta family member famously linked to reversal of cardiac hypertrophy in parabiosis experiments by Amy Wagers' lab (2013). Subsequent work by Novartis/Glass et al. (2015) disputed the original assays and showed GDF-11 can be myo-inhibitory like myostatin. Therapeutic role remains controversial.
Muscle Gain context: Increasing lean mass via GH/IGF-1 axis, satellite-cell activity, or anabolic signaling. GDF-11 fits this goal because its category (Longevity) and benefit profile align with the underlying mechanism.
Benefits relevant to muscle gain
- Possible muscle/cardiac rejuvenation (debated)
