I'm defintely seeing results in the mirror. And my strength is going up, but I'm frontloading with dbol, so it's probably the dbol. This being my first cycle, I don't know what to look for to tell if the t4oo is working. I'll tell you this, this shit hurts like a mother. Especially the second day after. The swelling is unreal. I just hit my left glute Tuesday, the first shot was my right glute. I'm not going to be able to hit the glutes next week, so I'm considering either splitting the next shot into both biceps. I was thinking about the quads, but I have to be able to walk for work, so I'm kid of scared to do the quad. In short, I regret buying T400. The pain is almost unbearable. I'm going to go with test e or c next time for sure.
