My doc's range started at 300. I tested at 253 and got hrt. I take 100mg per week and my levels are at 1400+ right now after starting in January. It only costs me about 15.00 every couple of months including syringes. My insurance wouldn't cover it unless it was low...which it was so the doc had no issues. But he didn't want me to get above 700-800 so he will knock my dosage back in feb which is my next appointment
