Don't know what you guys are paying for sust, sounds like alot. I just want to say that sust 250 is an androgenic steroid that contains four diferent esters of the natural hormone testerone. Testerone propionate has a rapid onset and a short duration of action.Testerone phenylpropionate and isocapropate have a less rapid onset and long durationof action.Testerone decanoate has a slow onset and a long duration of action. When these esters are combined the action starts shortly and after injection it is maintained for three weeks. So you get all of the esters working together for awsome gains when stacked with deca 200mg or d-bol. I say if you can get it a good price it is worth doing.
