1 7-alpha alkylated anabolics are very hard on the liver. This makes it that much more important for you to use products that help cleanse the liver as you go. Taking excessive doses and using it longer than 8 weeks will prove trying to the body. This means Naposim is unsafe to use. Simply follow the guidelines for use closely and take the necessary liver supplements to protect your health. Monitor your liver function through blood tests and take products like milk thistle, Liv-52 or ALA (alpha lipoic acid). Take one of these for the entire cycle if you want to risk by using Naposim.
