My first cycle was with 4AD (prohormone for testosterone) and 1-testosterone (legal designer steroid at the time). That was one of my favorites. Either one on its own wouldn't have been as good. 4AD doesn't raise test levels enough to make big gains, and 1-test by itself would drop natural test levels low enough to cause major side effects.
I had good results with Havoc too, although I wouldn't do that alone again. I won't run anything without test as a base. It's a shame they banned the original 4AD. That would have given guys an easy way to add test to an oral only cycle if they're afraid of injections.
