I agree too much RR. It seems really strong. Probably very low estrogen. It takes 3 to 4 days for LH system to react to small reductions in estrogen. Probably a couple of weeks to get to full testosterone output from 3 RR. During that time your estrogen is going to be very low. Try 1 RR for 4 days and then add a second one. Try just 2, that seems to be current consenses.
You shouldn't get lethargy. I get energy, but I taper in the estrogen suppressors. I'm very protective of my estrogen levels. I'm curently doing 2 RXT and 1 RR with 6 to 8 ActivaTE.
You might be able to add a third RR after a couple of weeks.
