I have never tried tren a. So I can't compare the 2. I'm running tren e 600 a week and test e 400. I didn't get any strength gains in the gym but I think my estrogen is fuck up. I'm eating at maintenance. So that probably messing my strength up too. I didn't get any sides till halfway through my second bottle. Sometimes can't sleep, lots of sweating crazy dreams. Sometimes I feel off when talking to ppl. I'm body is looking good. Muscles are getting hard. Would I use tren e again the answer is yes. I will be switching up the doses though.
