Decrease blood amino acid
Increase liver amino acid

It does this by inhibiting collagen formation, decreasing amino acid uptake by muscle, and inhibiting protein synthesis.* Glucocorticoids promote protein degradation and inhibit entry of amino acids in tissues (Primarily Branch chain amino acids).* Glucocorticoids also lead to utilization of amino acids by promoting gluconeogenesis directly and by permissive effect on Growth hormone.
