A
Stimulates protein synthesis and promotes tissue growth
B
Promotes lipolysis in adipose tissue
C
Directly decreases insulin-like growth factor 1 (IGF-1) production by the liver
D

Step 1: Understand the primary physiological effects of Growth Hormone (GH). GH mainly promotes protein synthesis, tissue growth, and stimulates lipolysis (breakdown of fats) in adipose tissue.
Step 2: Recognize that GH indirectly increases insulin-like growth factor 1 (IGF-1) production by stimulating the liver, which then mediates many of GH's growth-promoting effects.
Step 3: Note that GH increases blood glucose levels by reducing cellular glucose uptake, which is part of its role in maintaining energy availability.
Step 4: Identify the incorrect statement by comparing it to the known effects of GH. Since GH actually increases IGF-1 production, the statement that it directly decreases IGF-1 production by the liver is false.
Step 5: Conclude that the option stating GH directly decreases IGF-1 production by the liver is NOT an effect of GH, making it the correct answer to the question.
