Testosterone and estrogen blocker

I have a quick question. I’m currently 33 years old and I’m currently taking test c for low t. I’ve noticed over the last couple of years that my belly fat and love handles lol seem to be hard as hell to get rid of. So my question is while I’m on cycle should I be taking an estrogen blocker or anyother supplements that would help with this solving this problem. I’ve also noticed low energy and low drive to do anything.
