5 weeks is an odd duration. Personally, I would run the dbol for a full 8 weeks in combination with an aromatase inhibitor such as Arimidex at 0.5 mgs ED. Standard PCT should begin the day after your last intake and should consist of 1,000 IUs HCG 3x/wk (mon/wed/fri) and 20 mgs Nolvadex ED for a total of 3 weeks. Then, discontinue HCG and continue with 20 mgs Nolvadex ED fora an additional 3 weeks.
