Considered by many the best overall steroid for a man to use (side effects vs. results) Deca durabolin is most commonly injected once per week at a dosage of 200-400mg. With this amount, estrogen conversion is slight so gyno is no problem. Also uncommon are problems with liver enzymes, blood pressure or cholesterol levels. At higher dosages, side effects may become increasingly more frequent, but this is still a very well tolerated drug. It should also be noted that in HIV studies, Deca has been shown not only to be effective at safely bringing up the lean bodyweight of patient but also to be beneficial to the immune system.
