I am by no means a vet on trenbolone but here is what I have read and studied. ed or eod just keeps the blood levels on a steadier pace. I am currently on 100mg eod but I am dropping mine back to 75mg ed. its more of a dose during the two days but less spikes up and down. I am starting my second week with this dose and am starting to have some insomnia. Some of the side are a bitch but awesome stuff..
