Ok I am 41yrs old and on my first cycle in about 5yrs....started running sust and in about week 3 went to 1mil sust 250 and .7ml of tren ace eod along with 1ml test cyp 200 a week...I recently was told that after awhile tren will give you ED?! can't have that, I also have recently switched to 100mg of sust and 40mg of tren ace ed, continuing my cyp 200 once a week (its prescribed) so the same person who told me that told me that eq would be better to run for libido but I though eq was a nandrolone....some clarity on this please my goal is to keep what I have, get harder more defined and cut belly fat.
