This is taken from above:
Another way athletes have found to lessen the "crash", is to first replace the testosterone with a milder anabolic like Deca-Durabolin. This steroid is administered alone, at a typical dosage (200-400mg per week), for the following month or two. In this "stepping down" procedure the user is attempting to turn the watery bulk of a strong testosterone into the more solid muscularity we see with nandrolone preparations. In many instances this practice proves to be very effective. Of course we must remember to still administer ancillary drugs at the conclusion, as endogenous testosterone production will not be rebounding during the Deca therapy.
