I am 45. TRT. Intermediate lifter. Train whole body 3x/wk. 4x6@80%. Macros past 5 weeks average 220protein, 150 carbs, 70 fat. Up to 240 pounds. Strength and motivation are dropping. Have been on TRT for years (35mg 2x/wk subQ), started Anastrozole about 3 months ago (.25mg 2x/wk)and have been gaining weight since. Past 2 weeks have been thinking lab test is needed. What suggestions do you have?
