Two years after recovering from a brutal back surgery I stepped back into the gym 2 months ago. Before I was in great shape and diet was down to a t at 6ft 235lbs with low fat. I'm currently 205 lbs. Been lifting 5 days a week keeping my calories at maintenance 3000k with 200 protein, 300 carbs and 100 fat. Lifting 4 to 5 days a week. I just had my blood work done and my doc flagged me for low testosterone. So I'm going go start running testosterone at a low dose. I have been out the game for 3 years and forgot so much. What should I pair with the test to build lean muscle mass and should I change the diet up any?
