From one of Bill Robert’s articles:
Throughout the first five weeks: 50 mg/day Clo (two capsules), except Day 1 is 300 mg in six divided doses.
In first two weeks, 200 g/day protein more than usual, but hold fat and carbs moderate enough to avoid significant if any fat gain. In the following four weeks, diet the first three, and diet or use maintenance calories for the fourth, in all cases keeping protein at least 180 g/day.
Day 1: 100 mg (200 IU) TA in morning. 10 mg D five times per day in divided doses, which might include middle of the night if I awake briefly enough to have a pre-made Met-Rx. Cyt: 125 mg (half tab) on arising and 62.5 mg six and then twelve hours later.
Days 3-11: 50 mg (100 IU) TA/day, 250 mg Cyt as above, and 50 mg Diana as above.
Days 12-14: No TA, but otherwise same as days 3-11.
Weeks 3 and 4: Diana 10 mg on arising, and 10 mg four hours later. Cyt ? tab on arising, and oxandr 20 mg on arising.
Week 5: same, but on basis of blood test, Cyt may be dropped if estradiol levels were below normal.
Week 6: Clean, unless T was not above normal in blood test at end of week 4, in which case Clo use will be continued in week 6."
So PCT amounts to the use of Clomid and Cytadren throughout, or nearly, the entire 6 weeks. But notice this wasnt a Tren only cycle as Dianabol and later oxandrolone were used, although he says oxandrolone does not aromatize.
