Nolvadex is a popular and powerfully effective Selective Estrogen Receptor Modulator (SERM) that is often referred to as an anti-estrogen. Nolva, as it’s commonly known, can be used as an anti-estrogen during an anabolic steroid cycle in order to prevent estrogenic related side effects. It is also used as part of a Post Cycle Therapy (PCT) recovery plan, which is its most common and beneficial point of use for the steroid user. For the purpose of estrogenic side effect protection during anabolic steroid use, 25mg per day is common.
