IMO, cutting isnt the ideal time to run a first cycle, as the main effect of steriods in BB is to build new muscle tissue. in order to do that, you need to eat enough food to make gains. for a guy your size and with the experience you've mentioned, i wouldnt be shocked to see you keep 10-15 lbs after your first cycle, if the main goal was to add mass. if you put yourself in a calorie deficit, i think your results may not be as good. 

personally, i never let myself get overly fat, even in the depths of my off season. i try to add muscle while staying fairly lean and when it comes time to diet down, i never need to cut too dramatically, until the very end. i believe that you can gain new muscle while cutting fat if you keep enough clean food going into your system. personally, i would throw out the scale and go by the mirror and progress pics. many times, when i get in the grove of my diet, i get leaner each week but the scale stays the same due to new muscle i've developed. 

i beleive that test should be the base of every cycle. you can use an AI to control estrogen and water retention when your goal is to cut or use less AI in the off season and use the added water to help develop more keepable gains. 

wk 1-12

test e or cyp between 250-500mg EW

aromasin 12.5mg ED OR adex .25mg EOD to .5mg EOD, depending on estrogen levels

wk 1-8

anavar 50mg ED

as for sources, you've already found the right place. i am currently using geneza pharm from the naps site. GP has always been good quality gear and delivered the gains i've expected.
