The information out there about growing new muscle is sketchy. This is because of the differences in small details. Your body grows new muscle cells each day, but the amount of muscle fibers is not changed. Your muscle fiber can be affected by many things, which make it harder, fast twitch, slow twitch, or bigger in size (hypertrophy). So with that information, I give you Hard FX. This product gives you more muscle mass by increasing testosterone levels. A normal testosterone booster might take a few weeks to take affect. This is where a difference comes in with Hard FX. 

It is designed to work quickly by stimulating 7 factors that enhance the bodies natural testosterone production.Your body will be able to synthesize more testosterone after taking these pills. Some of the proprietary blend that makes up this athletic enhancer includes D-Aspartic acid, Trigonella foenum-graecum seed extract, coleus forskohlii extract, and 7-methoxyflavone. 

One bottle comes with 112 capsules. For the best results possible take 2 capsules in the morning and 2 in the evening for 8 weeks. After this time you should cycle off for at least 4 weeks. The reason why you want to cycle off after 8 weeks is because your body will get too used to this extra testosterone production and may stop producing as much on its own.
