I'm using it now for my PCT from a Prohormone cycle. Seems to be working, but it is very EXPENSIVE at $55 per bottle. This is 6-OXO Extreme.
For PCT it is recommended.
Week 1 - 10 Pills Per Day (Split in two doses)
Week 2 - 8 Pills Per Day
Week 3 - 5 Pills Per Day
Week 4 - 3 Pills Per Day
75 Pills in a Bottle!
On anabolicminds I saw an advertisement for $35 a bottle I think.
