The labs at Advance Muscle Science (AMS) have created the ultimate prohormone that rivals and resembles the performance of the older, banned prohormones. However, when it is stacked with other supplements by AMS, 4-AD is an incredibly powerful formula you will not want to exclude from your regime.

Of course, you do not have to use it as a stacker to benefit from it. On its own, 4-AD produces incredibly amazing gains that will last.

Banned prohormones created testosterone in the body, which is why so many body builders found benefits from using them. This 4-AD product goes a step further. The new and improved 4-AD formula is comprised of ingredients that are already found in the tissues of the body. These all-natural ingredients work in the body to naturally be converted into testosterone. The conversion is thanks to 3beta-HSD, which is a natural enzyme in the body.

Other prohormones cannot even compare to the conversion power of 4-AD. Products like the banned androstenedione had lower conversion rates of testosterone and were harmful enough to be banned from usage. These banned substances were so popular because they would not convert to estrogen and possibly DHT as well prior to being converted to testosterone. 4-AD does not face this problem either. It is converted automatically to testosterone without any middle conversions that may slow the process down and leave things like estrogen (which we do not want!) in the body.

AMS has also developed another, high-testosterone converting product, 1-Androsterone. Both products are 100% legal and stimulate naturally occurring hormone production, reducing the risk of harm to your body that synthetic products are capable of producing.

In no time you will have more naturally occurring, free testosterone in your body thanks to 4-AD. No conversions to DHT or estrogen will occur. Plus, since the substances that make up the 4-AD formula are naturally occurring in the body there is less risk for negative SIDE EFFECTS! What more could you ask for in a prohormone?

What about a product that is also more androgenic? 4-AD provides this for you as well! Androgenic products have properties that are more masculine so your more masculine characteristics will come to the forefront. What more could any man want?!

This means that your sex drive and performance is heightened, your ability to trim fat and gain muscle is increased, and your testosterone levels are skyrocketed!

4-AD can be stacked with AMS's other testosterone-creating supplement, 1-Androsterone. With these stacks, the gains you see in muscle mass and strength will stun you! In no time, you will have the perfect, chiseled body you have always wanted. Of course, your energy is also increased so no matter what you hope to gain from 4-AD, you will be alert and full of energy just by taking this supplement.
