Is this your 1st cycle? Maybe you should preserver a bit longer. Its said that usually the 1st week acne is worst on cycle. It may settle down, you could try using benzyl peroxide in the manner described here

It did wonders for me.
If you are able to get a dermatologist to prescribe you some cortisone tablets that should clear you up very quickly, you cant stay on them long term though. Then you could take an antibiotic like Alprim (Trimethoprim) & by the time your off the cortisone the Alprim should be working and keep you clear.
In just 1 week at that dose your natural testosterone production will not have shut down you possibly could almost get away with no PCT in my opinion. See what other people think though.
Hope that helps, good luck.
