It did make me aggressive. I am a very very calm person with a lot of self control. however, the week before my contest, some guy was behind me at a stoplight, honking and flipping me off. I followed him into a parking lot, jumped out of my car, and started yelling at him. Then i thought "if i go to jail, i won't be competing next week". I couldn't believe I did that shit. It was WAY out of my character, but the Halo, mixed with my diet, sugar cravings, stress, and everything caused me to freak out. You just gotta make a mental note to keep everything in perspective. Self control comes naturally to me, but when i'm on precontest drugs and a strict diet, i gotta make it more of a priority.
I would do halo 3 weeks at 20mgs per day prior to a show. I DO NOT recommend anyone take Halo who is not a competitive bodybuilder. THere are other drugs you can take that are less harmful and produce a significant anabolic effect. Halo is strictly for pre-contest and it's use is for a short interval. Makavelli says 10 days out.....I can agree with that. I say 2-3weeks out.
FISTS OF FURY!!! good luck bro.
