You're taking 2.5mg letro a day? Holy hell that is a large dose. .35mg is a much more reasonable dose. Coming off after .5mg is basically like you didnt taper. Is your libido still up there, as in can you even get the faintest of erections? E2 levels that low can mess with libido, hard. No pun intended.
Use Nolva, YES. You're also going to need some cabergolin or other prolactin control. Because of the trenbolone.
Nolva, yes. I'd say front load 120 mg the first day and use it for atleast 2 weeks at 20mg a day.
