As for me, doses are huge. After 16 weeks on a cycle (TE 500 mg/wk, hCG 500 UI/wk, Arimidex 0,5 mg/wk) and 2 weeks of T washout I ran my PCT protocol for just 4 weeks: 10.000 UI of hCG, 18 mg of Arimidex and 1200 mg of Clomid were just enough. One week after the PCT my T was beyond (for about 4 nmol/l) the upper limit of the range, E2 was in the middle.
Power PCT should be great for guys after a long cycles.
