dont do a decca only cycle, at your size test would be a good addition. what are you workout routines like? what is your diet going to look like? the deca is a protein synthesis activator so getting (at your size) 400+ grams protein per day is necessary. also, the test of choice for you first cycle may be sust or omnadren (my choice, but causes more water retention). do this at 250-500 mg/ week. you never know however how your body will react to all this seeing that your steriod receptors will be opened for the first time when you start your cycle. if you are looking to bulk, this is a great idea for a first time cycle (which will be your best if you put work into it).
also, research clomid for post cycle ... have anties on hand (nolvadex or proviron).
if have any ?s just ask
