for size, change your diet and up the carbs and protein, UNLESS you respond better to high fats and low carbs. then add dbol and focus on contracting the muscle through your lifts so we dont just add water weight. at the start of the cycle, have your test, eq, dbol and run those and have (whatever "cutting compound"), minus the dbol for the majority of your cycle, then when youre ready to cut, drop the test c/e for test p(or faster acting to drop water weight) then drop the test low to 100-200 and run your eq high and (whatever "cutting compound") add once you drop your calories and carb cycle. only eat your carbs pre and post work out to help knock out calories.
once you get into an extreme enough cut, clen, t3/t4 combo can come into play. if youre brave enough, halo would be good too lol
if youve been in this for any length of time, you know its diet and not the compounds so i would focus on the diet and the let drugs be secondary. personally i think its too late to try and bulk then cut because summer is right around the corner and youll have an extreme cut which wont be fun.
obviously this is a hypothetical conversion and you shouldnt listen to me
