You can do anything safely if you try. Cycle isn't too harsh IMO just long orals.
Add n2guard 7caps/day during the dbol run and 5 after. I would up the test to 500mgs.
WIth how estrogenic dbol is, I would actually only run it for 4 weeks. In my opinion, tbol is a far superior choice to dbol simply due to side effects. Everyone is different and has different goals so that is just my opinion.
