From somoene who have used tren for years in many cycles. I can share my own experience. I always used Tren Acetate with great results, even when shot EOD in all cycles. Aggression (not the good type that just helps in the gym) always happen to me as well as some insomnia. But still worth it.
BUT with Tren Hexa (AKA Parabolan/Trenabol Depot) the sides were MUCH MUCH (did I say much?) more significant and absolutly non-tolerable. Tren Hex builds up in the body, so what happens is basically if you inject the SAME amount of total Tren in your cycle with Acetate or Hexa, you'll probably get much higher concentration of tren in your body towards more at the end of your cycle (and less in the beginning had you used tren acetate). I hate every day or eod injections, so i decided to try Tren Exa in my last cycle which ended just recently. Assuming that every 3rd or every 4th day of 200-400mg of tren would be more or less the same as the tren acetate 75mg or 150mg EOD. Seems I was wrong. I am talking about UNREAL insomnia, plain simple couldn't sleep at all without the use of prescription sleeping pills (melatonin and all the natural crap did zero). I personally will never ever try Tren Hexa again, back to Acetate for me.
