Very informative thanks for the info, my first time running tren and I picked e, about 6 weeks in now and the sides i have are sweats at night and tossing and turning I wouldn't call it insomnia cause I do get some rest but I probably only get a solid 4 or 5 hours of sleep. Other than that no other sides that I can notice, never had any issues with my first cycle as far as aromatization, so I'm running 250 test e and 200 tren e every twice a week(Monday and friday) with 10mg arimidex
