In my opinion, I wouldn't waste it from day one, give the enter a chance to break down. If I were going to be overly safe, I would start at the ten day mark. But you could prob start a few in. I wouldn't even really be trippin on 2-300 mg.
I ran 750 hg sus, 600 deca, anadrol and dbol kicker, and anavar for a month later. I should have started from the very beginning with the dbol and short ester in sus, I am a dip shit. I am just gonna pray I can get it to go down enough. The funny thing is I had adex and intended to use it from week four on, but my buddy needed it bad, so I hooked it up. Ordered more a couple weeks later, and my order took a long time to come. Another funny thing is that my buddy sold the fucking adex. Bastard bitch.
