First of all, remember that bodybuilding and steroids are both about being gradual and patient. Secondly, always make sure to have ALL of your ancillaries and PCT on hand before you start the cycle. Finally, a DBOl only cycle is not a good idea, and you should rather do the testosterone solo cycle in the following manner:
Weeks 1-12
Testosterone enanthate 400 mgs per week (split into 2 dosages of 200 mgs)
Aromasin 10 mgs EOD (from the first day of the cycle)
Then wait two weeks, and do the perfect PCT of Clomid, Nolvadex, HCGenerate ES, Ostarine, and N2Guard. This is yet another golden rule of proper cycling - make sure to run a very good PCT, because without it you will lose the gains made on cycle, and will have a hard time recovering your natural testosterone production.
