Ok a few things -
1. 0.25mg of arimidex E3D is no where near a high enough dosage for a 500mg/week testosterone cycle. You need to use a dosage of at least 0.5mg EOD. Bump up your dosage and I suspect your acne will start to go away
2. Here are some tips for removing acne:
1. Sun tanning is a very effective means of reducing acne and drying out the skin.
2. Use anti-acne lotions at least once per day. Go to your doctor and ask him to prescribe you a topical acne cream. It'll work better then anything available over the counter and your insurance will cover it.
3. Make sure you are showering 3 times per day: upon waking, after workouts and before bed.
4. Zinc containing creams are very effective and available over the counter. Apply them to your trouble areas.
5. Black ointment is extremely effective. It stinks pretty badly, but I am pretty sure you can deal with it for a couple of hours in order to get rid of acne.
6. Baking soda is one of the best natural exfoliants you can use. Gently rub baking soda on your trouble areas when showering to remove layers of dead skin and help remove the acne.
3. I am not sure who gave you advice for your PCT but nolvadex alone is no where near sufficient for a PCT. Your natural testosterone production is not going to recover with such a crappy PCT. After your cycle run the perfect PCT protocol ->

I would keep your cycle length at 10 weeks. That way you can order everything you need for the perfect PCT protocol and have it arrive in time to run a proper PCT after your cycle. You can order everything you need for the perfect PCT from sarms1.com ag-guys.com and n2bm.com
Keep using the arimidex at 0.5mg EOD for 2 weeks after your last injection. 2 weeks after your last injection start the rest of the PCT drugs (clomid, nolvadex, aromsin, ostarine, cardarine)
