The activation of Akt results in skeletal muscle growth/maintenance since it controls the phosphorylation of a number of substrates involved in MPS including mTOR (and its downstream targets 4E-binding protein 1 (4E-BP1) and p70S6 kinase) and glycogen synthase kinase 3 (GSK3), as well as, the inhibition of protein degradation via the forkhead transcription factor (FOXO) pathway (Consitt et al., 2006)
Tesamorelin + ipamorelin work through complementary GH-release mechanisms: tesamorelin activates GHRH receptors on pituitary somatotrophs, while ipamorelin selectively stimulates ghrelin receptors without cortisol or prolactin elevation
