Have you ever ran SUS500 before? I've ran a couple of cycles and you are correct sir that it will shut you down hard. I was dosing strong 5 pills/day and that probably didn't help much with the shut down issue. I ran a 6 week cycle the last time and was completely shut down from the 3rd week onward all the way until the 3rd week of my PCT. Testes eventually came back to normal size though. You are gonna shed some hair as well with the SUS500. On the positive side, my gains on the SUS500 were quite impressive, maybe a little wetter than I would have liked, but good strength and mass gains on it. I'm curious as to the answer to your question as well. I'd like to avoid that massive shutdown if possible the next time I try the SUS500.
