New to the whole PCT thing and would love some advice

[Scourtle]

Hi there, I'm currently on a 3 month cycle of 1 ml of Tren A and .75 ml of test-e (In Canada it seems to be measured in milliliters instead of milligrams) and I inject every 2 days. This is my first cycle and to be honest, I want it to be my last cycle. So I was just wondering what would the most effective way to cycle off and help restart my body, I don't know anything really about PCT's so any information about what to use would be helpful, I'm 19 years old and I went into this in a spur of the moment kind of deal because my friends were doing it and I saw the massive amount of progress they were having so without any proper beforehand research I jumped into this which is something I rather regret, Don't get me wrong the muscle and strength gains I've made are nice, but I'm just thinking I could have made the same gains naturally over the course of time. To be honest I'm scared about the side effects. Any PCT stacks or recommendations would be appreciated. Thanks
