Read Off Label rates the evidence for GDF11 as Preclinical and the benefit magnitude as variable, producing an overall grade of D+ (3.7/10). Loffredo 2013 Cell reported anti-aging cardiac effects; follow-up work disputed specificity and found GDF11 indistinguishable from myostatin (GDF8) using older reagents.

GDF11 has a med risk profile in published human data. Legal status: Experimental. This is not medical advice — see the disclaimer.

Bottom line

Read Off Label grades GDF11 as D+ (3.7/10) based on preclinical evidence, variable benefit magnitude, and a med-risk safety profile.

Loffredo 2013 Cell reported anti-aging cardiac effects; follow-up work disputed specificity and found GDF11 indistinguishable from myostatin (GDF8) using older reagents.

Typical use: No established clinical dose — Experimental.

What this is

Loffredo 2013 Cell reported anti-aging cardiac effects; follow-up work disputed specificity and found GDF11 indistinguishable from myostatin (GDF8) using older reagents. Field is unsettled.

Mechanism

TGF-β superfamily growth differentiation factor; parabiosis experiments suggested rejuvenating effects on heart, brain, muscle — contested and partially retracted; may improve cerebral vasculature

Dose & route

No established clinical dose
