First of all, if you are running a cycle of anabolic androgenic steroids your Post Cycle Therapy needs to be based upon usage of a clinical SERM drug. These are usually either Clomiphene(Clomid) or Tamoxifen Citrate(Nolvadex). Clomadex is NOT a SERM drug. It is an an inadequate poorly formulated otc product named in a manner to capitalize on the confusion and ignorance of consumers. If you purchased only Clomadex do NOT start an AAS cycle.
