Pullup issue

[m33]

I've recently tried to incorporate a heavy amount of pullups into my workouts. I get through them just fine, but they drain all my energy. Even with taking a pretraining energy product and drinking an energy drink during the workout. I feel so damn drained after them I don't feel like continuing the rest of my workout. Any ideas?

What exactly do you do? How many reps? sets?
On back day only? What does your back routine look like?

How much do you weigh?

My back training sessions are very demanding. Make sure and take plenty of rest between sets. What does your set up look like?
