When looking at the androgenic side effects of Deca Durabolin, we will find they are highly dependent on genetics. If you are predisposed to male pattern baldness it is possible for hair loss to occur. It was going to occur at some point no matter what you did, but the Nandrolone hormone may speed it up. Those who are sensitive to acne may also find the hormone causes breakouts, but most should not have a problem. Even those who are genetically prone to male pattern baldness will rarely have an issue with this steroid. Remember, while androgenic its androgenicity is extremely mild. In fact, those who are sensitive to androgenic effects often find Nandrolone to be one of the most well-tolerated steroids. It’s important to note – some will be tempted to combat the androgenic side effects of Deca Durabolin with a 5-alpha reductase inhibitor. The Nandrolone hormone is metabolized by the 5-alpha reductase enzyme, but in this case, this metabolism reduces the hormone to dihydronandrolone (DHN) not dihydrotestosterone (DHT) as it does with testosterone. For this reason, the use of a 5-alpha reductase inhibitor will enhance the Nandrolone hormone’s androgenicity and should be avoided.
