I've got a question about Sustanon 250 and Deca cycle. Currently I'm on the third week of an 8 week cycle. I have to run a lot in my profession and need to keep my run time down (fast). Since I've been on, run times have gotten super slow and I can't do anything about it. My job wants to give my yearly evaluation within the next couple of weeks. Any advice? I am thinking about stopping it all right now but don't know the affects it will have.
