Amazingly horrible,,,thats all I can say so far about Tren. After my first week I have put on almost 8 lbs and over 1/4 inch on both arms, and keep in mind that I am on a very restricted calorie cutting diet as well as I have only worked arms once this first week. Amazing, but I can tell you this Tren makes me feel like absolute hammered dog shit all day long. I cant sleep at night and I just feel horrible, and if you suffer from anxiety, be very careful with this mess it can be very rough on you...That extra 1/4 inch measurement was taken yesterday,,,, and when I woke up this morning my wife says "oh my god baby, your arms look way bigger than they did yesterday"!!!! Looks like Im gonna love to hate this shit.......
