I have heard from many people that Sustenon 250 is a painful drug to inject and I totally agree. I injected 2ml/week and on the second day after, I felt as though someone had punched me in the thigh! From what I have read it is the propionate ester that causes all that pain. So my question is, if I begin a cycle of say 12 weeks......shooting propionate 100mg EOD...and then adding 75mg Tren EOD for the last 8 weeks....that sounds like I am gonne be in some serious pain! The sustenon was really irritating to me as I said. I dont mind being a man and doing what I have to do, but if the propionate ester was the cause of that much pain shooting Sustenon only once a week...I can only imagine what it will feel like running it EOD! Any thoughts?
