Tamoxifen Citrate is a SERM with both estrogen agonist and antagonist properties. As an anti-estrogen, Nolvadex functions by binding to the estrogen receptors in the place of estrogen. This binding prevents the estrogen hormone from performing its action in certain parts of the body. By preventing the attachment in such receptors, this also protects anabolic steroid users from gynecomastia, which can be caused by anabolic steroids that aromatize such as Testosterone, Dianabol, and Nandrolone andBoldenone to a degree.

HCG is regularly used by many anabolic steroid users throughout a cycle or as part of the PCT protocl. During the cycle, the idea behind supplementation is to combat hormonal suppression that occurs due to steroid use. Use after cycle is to enhance or produce a more efficient recovery.
