I believe it was around 2,900-3,000 when I did it pre cycle to calculate. So 3,500 calories is what I had to eat or more to gain weight. I agree , don't want to gain fat by eating incorrectly. But def feel better eating more then eating less. I'll have to crunch out a solid diet at 3500-4000 so I keep gaining but don't go over board. Thx!
