Dont go back too 200 mgs just keep it at 400 and then stop and then hit 6 oxo
6-OXO has to be tapered off or you risk estrogen rebound and low testosterone. ATD and RR have long lifes so there is as much problem with Estrogen Rebound. I still taper them anyway. 4 days between 100 mg drops of 6-OXO to taper. You should also taper on the same way to driving your estrogen extremely low resulting in low white blood cell counts, low HDL and loss of libido. 6-OXO actually can work very well when tapered properly and combined with a SERM. You can go as high as 600 mgs, but absolutely necessary to taper off properly at thst high of doses. ATD and RR are better choices. I actually go for 50 mgs ATD and 1 RR. Higher estrogen with no libido issues.
Coming off of 1-AD you will be very low in testosterone and because of that you will also be extremely low in estrogen. This is where a SERM really pays off in the beginning of post cycle therapy where it gives you selective estrogen support. Toremifene is absolutely remarkable for fast recover.
You really could use some testosterone support like 4-AD, testosterone, or TST when on cycle. 1-AD is suppressive of Testosterone. Short of that, 300 mg of DHEA will provide estrogen support along with some testosterone. You can probably go higher but you need to beware of gyno from the estrogen. Take no chances if you think you showing gyno problems.
Not taking 1-AD within 4 hours of sleep will help little with testosterone suppression. 1-AD has basically a 4hr lifetime so protien blood levels needs to be timed to match 1-AD blood levels. 200 mgs is small dose and hard to match up to meals.
