it depends on how long you have untill your show. if you have about 16 wks, i would run gear all the way in. unless you are overly fat, i believe that in the early stages of dieting, most people can add a little new mass while leaning up. you have to remember though, one cycle is probably not going to put you over the top. theres a good chance that no matter what you do, you aren't going to be able to make vast changes in a few month period of time. i think the drol would work fine but i would stay away from the dbol, as it has a high conversion to estrogen and IME, you won't lose fat as easily. so lets assume you have 16 wks and want to use sust and drol. i'm suggesting the addition of EQ, as it is a good anabolic that will help you gain while not holding a lot of water. i would also consider winny for the last 4 wks, to harden up and dry out, more than you would on tren alone. heres how i would add them into a prep.
**note- with the adex, start at .5mg EOD and be willing to go up to .5mg ED and possibly 1mg ED, depending on how much water you hold from the sust. for the first 8 wks, .5mg EOD is fine. around 6 wks out, i'd consider going to .5mg ED and only if needed, in the last 2 wks, up it again
