Bro I think your fine on 2x/wk, but why you going so high on the sust? Have you taken it before? Studies show that more is not better on sust. I use sust in every cycle that I take, and for ME, i don't see a differnece when i go to 500 vs 375. I would start it lower and when you see gains slow, raise it at that point. Also, I'd run a sust cycle for 14 weeks. I really start seeing the best start about week 8 and by 14 it's been a great 6 weeks! I've even run it for 16 weeks..but a little harder for pct.
