I have only had two side effects from tren that I didn't like :
1 - no appetite. I mean, seriously I could not believe this shit. I have done 3 cycles with it and never again. Don't get me wrong, I put on about 2-3lbs those cycles, which doesn't seem like much. However, adding lean weight while having a daily caloric intake of basically nothing is not normal. It would get to the point that just a food commercial on tv or a billboard would make me feel queasy. I simply did not want to eat. A few days each week, I would have nothing more than a protein shake about 2pm after training. Nothing else. I had no appetite and just found food impossible to even think about. The days I did eat, I would force myself to eat a chicken breast or small steak. And then nothing else. I literally needed no carbs at all. But had mad energy. Weird phase I have ever been in each time.
2 - Had a very strange test in my mouth. Some people say they get a metallic or copper taste, but this wasn't the case. It was more like a "smokey" taste. Best I can describe, I don't smoke but that is what it tasted like. It could have been all in my head though because no one else could smell it. (I asked)
I have heard that Tren Enan is much easier on the body in terms of handling side effects. Nevertheless, I have no desire to use tren at all anymore.
