I did it and now am going to a specialist to try and get my sperm back to normal. My sides were no sleep, wanting to rip peoples head off for no reason, sweating like crazy and lets not forget my sperm count is next to nothing after 4 months. I started with test and felt like a kid again. Loved it. Then I added tren and it was hard to maintain control of myself. I am a rookie but I can tell you tren is hard core. I have a friend who lost the majority of his friends and quit juice for good bc of tren. My advice is stay away. I am sure it could be used repsonsibly but personally it is not for me.
