Among the widely used steroids is Deca-Durabolin. For the past three decades, Deca Durabolin steroid has delivered great gains to people looking for muscle mass and has the ability to reduce joint pain and boost the body’s immune system. The most important benefit of Deca-Durabolin for both amateur athletes and bodybuilders is that it doesn’t have serious side effects since it doesn’t convert to estrogen like other compounds. As such, Deca-Durabolin does not have severe or higher degree side effects that other compounds might have.
Despite appearances, this theory has very little evidence to back itself up with no real scientific evidence to suggest that a bridge is even possible, although granted that the majority of our working knowledge comes through trial and error. However, even the proponents of a "d-bol bridge" admit that complete restoration of LH function will not be achieved until one is completely off of all compounds. With that said, it is unlikely that a "bridge" will help to maintain muscle mass while you are able to recover both HPTA and LH function. The only solution is to come completely off all substances and run a proper post-cycle therapy.
