An ancillary drug, for our purposes, can be defined as any drug that can be taken to off-set, the side effects sometimes associated with the use of anabolic steroids, or, to increase the desired effects of anabolic steroids. Didn't think the last part was coming, huh? Its true, specific non-anabolic drugs work very well with anabolic steroids and we are not just talking obvious drugs such as insulin and growth hormone (although we will have future discussions and guidance on both). Side effect prevention purposes range from various angles. As we've said before the main ones are your skin, your hair, your sex drive (and also those lovely raisin nuts juice causes you to have as testicles) and your degree of water retention. A good portion of these side effects stem from the relationship of estrogen and progesterone with respect to the male body. Some of the effects are caused by the sheer effect of the androgens alone. We will be able to greatly minimize side effects with proper ancillary drug usage, but there is no guarantee that we will eliminate it. The effectiveness of these drugs has everything to do with your diligence in using them correctly, and, your genetics.
The side effects of Nebido can include those of an androgenic nature. The androgenic side effects of Nebido are, however, highly dependent on genetic predispositions and will not affect all men. The possible androgenic side effects of Nebido include accelerated hair loss in those predisposed to male pattern baldness, acne in sensitive individuals and body hair growth.
While by no means always necessary, some men may find the use of a 5-alpha reductase inhibitor to be useful. The testosterone hormone is metabolized by the 5-alpha reductase enzyme, which reduces the testosterone hormone to dihydrotestosterone (DHT). The DHT is what leads to the androgenic related effects. By incorporating a 5-alpha reductase inhibitor, you will reduce the hormones androgenicity. It will not be a complete reduction, but it will be significant. However, such inhibitors are not always recommended and should only be used as needed as they can hinder the potency of the testosterone hormone.
