I did the same thing jucied athletics did; kept the dosages sane. When I first tried tren, I used tren-hex @ 40mg and tried to go every 4 days. The response I got was immediate and awesome; I could practically live in the gym! With tren-hex though, on the fourth day I could really feel it starting to wear off so I went to every 3rd, which worked out great for my first 8 week cycle of it. No sides or anything and I kept all my strength gains. With tren-ace, I needed to do it about every other day. I think a good rule of thumb when using tren is to determine, with the first shot, how you react with the smallest dose to start- I tried as much as 80mg every 3rd and didn't feel as good as when I only did 50. After your very first shot, pay attention to when it begins to wear off and administer accordingly. You'll be glad you did!
