My advice on tdee is always under estimate then over estimate. When I first got really serious about this I bulked and cut and realized this was a waste of time. Instead I always consider myself in a body recomp diet. I eat 300 calories over my tdee daily and adjust cardio as needed. I add mass with very little fat gain. I do gain muscle at a slower rate then other but my bf stays at 10% and in the event I ever decide to do a show I will hold onto a hell of a lot more muscle then someone who has bulked up to 18% bf.

Of course everyone is different and you would have to decide how much over your tdee you should eat just be careful you don't gain excessive bf. I have noticed and I think every vet will agree, men bulk much better at a lower bf.
