I've actually been done with my cycle for almost 2 months now... right after that, I started a 2-3 week course of letro while administering my usually dosage of HRT test (this is doctor-prescribed, not self-regimen). Right after the letro, instead of using nolva to prevent estrogen rebound, I started using Sustain Alpha + Post Cycle + Unleashed... I have to say, I feel pretty decent. It's been almost a week since I stopped the letro, I know it takes a while for the body to stabilize afterwards... but I'm feeling ok... no signs of heavy estrogen and libido isn't bad.
