In the presence of adequate protein and calories, Boldabol promotes body tissue building processes and can reverse catabolism. As these agents are either derived from or are closely related to testosterone, the anabolics have varying degrees of androgenic effect. Boldabol, as well as other anabolic steroids can also stimulate erythropoisis. The mechanism for this effect may occur by stimulating erythropoeitic stimulating factor. Anabolics can cause nitrogen, sodium, potassium and phosphorus retention and decrease the urinary excretion of calcium.
