When you look up PCT online, you will find some pretty complicated cycles out there. PCT will always consist of a SERM, or selective estrogen receptor modulator, which works to improve the levels of LH and FSH mentioned above. Many athletes will also incorporate HGH or hCG into their PCT, but if you ran an Anavar-only cycle without any other steroids, these compounds are not necessary. For the most part, all you need is three to four weeks of Clomid or Nolvadex at the recommended therapeutic doses for your Anavar PCT, and you should start your PCT three days after your last dose of Anavar.
The Oxandrolone hormone does not carry any estrogenic related side effects. It does not aromatize and cannot lead to gynecomastia or water retention due to increases in estrogen levels. It further carries no progestin related activity, which again supports no estrogenic related side effects. Due to water retention being impossible with this steroid, this will decrease the risk of high blood pressure. Excess water retention can promote high blood pressure. Some steroids that do not aromatize can lead to high blood pressure, such as Trenbolone , but Anavar is rarely associated with this trait.
