Hi Arabian ,I wanted to change recently as an option because was having alot if sides which I don't usually have ,at the time I wasn't 100 percent sure if it was the abombs or the tren or both ,after now dropping the abombs it's starting to become clear it was purely that combo of abombs tren for me and after a week off of abombs my sides are very manageable now on the tren ,mainly only the night sweats left and small bit if lethargy but my workouts are back to full intensity.so just giving it another week ,if it remains like this I will continue tren ,if for some reason those early sides reappear I Will drop tren and continue in npp for duration of cycle !
