Carnosine vs GDF-11

Carnosine vs GDF-11 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Carnosine
Anti-aging & Longevity

L-Carnosine (beta-alanyl-L-histidine) is an endogenous dipeptide found in high concentrations in skeletal muscle, brain, and heart tissue. First discovered by Russian biochemist Vladimir Gulevich in 1900, carnosine has been investigated for over a century for its multi-modal biol...

GDF-11
Anti-aging & Longevity

Growth Differentiation Factor 11 (GDF-11) is a member of the TGF-beta superfamily that gained significant attention following a series of parabiosis studies from Harvard/Stanford labs published in Cell and Science (2013-2014) suggesting that circulating GDF-11 declines with age a...
