I was wary of tren's sides, so I delayed it a bit few years in to my bnc journey. Honestly I never experienced any of the horror stories, only the first time when I was aggressively cutting and I felt hypo, tired and angry af. To my surprise I was lifting really heavy numbers in the gym.
Second time with tren hex was awesome, I was eating maintenance and some days over as expected strength skyrocketed.
Third time was ace time, it was overall fine, I liked the effect again. Ed injections.
Edit: forgot to mention first time was tren E.
