According to this study, from my understanding, elevated insulin around the same time as GH completely blunts the free fatty acid release. Even with exogenous administration.
But instead, amino acids, insulin and HGH have a synergistic anabolic response. So less fat burn, more protein synthesis.
I’m not the greatest at breaking down these research papers but that what I’m getting from it.
“The fat mobilizing effect of HGH are inhibited by concentrations of insulin similar
To those obtaining in the post-prandial period”
The metabolic effects of human growth hormone may be segregated into two classes which can be termed “insulinlike” (or “anabolic”) and “contra-insulin” (or
