Estrogens are anabolic in skeletal muscle & bone but decrease stiffness in ligament & tendon (increasing risk of pulls and ligament rupture & decreasing performance). Despite increased collagen synthesis in ligament, E2 decreases the collagen:elastin ration, due to upregulation of MMP-13, which degrades collagen but not elastin. Despite increased collagen synthesis, UTS & modulus (mechanical properties) decline due to inhibition of lysyl oxidase activity by estrogen.For It’s more so the thinking that estrogen is anabolic. Just like testosterone. Weather that be endogenous test or injected/ endogenous estrogen/injected.
I’m taking this stuff to help build muscle, I want that to be as affective as possible.
The estrogen receptor alpha and beta both responsible for anabolism as well as collagen synthesis.
Would you disagree with that ?
