there have been a few good posts on this so far.... but i'll still throw in my .02

without test, you dont have a cycle, period. testerone is the most basic steroid to achieve growth and greater strength. the androgenic effects of testerone compliment the more anabolic effects of a compound like deca for more gains than you would get on either alone. also, test allows you to keep your sex drive and inherent 'maleness' while using steroids that suppress your hpta.

without test, you're likely to be depressed and unhappy with your cycle. i know that id never runa cycle without some form of test, and i think most if not all bros on here will agree. test is king.
