Mine had me some on 1500iu per week as well along with 100mg of cypionate and .5mg of arimidex 2 x per week. Gave me crazy acne on my back. I toned it down to 600iu per week and I seem to be doing better.
I feel good on 500 IU per week, divided into 2 doses of 250 IU a piece. This is in addition to test cyp. I use testicular fullness as an admittedly imprecise gauge.
