Steroid hormones bind to plasma membrane receptors

Likewise, a novel isoform of ERβ, termed ERβ2, containing an in-frame insertion of an exon of 54 nucleotides, resulting in an insertion of 18 amino acids in the LBD, was recently identified first by screening rat prostate cDNA library, and is also expressed in human cell lines. 43 ERβ2 binds E 2 with lower affinity (Kd = 8 nM) than ERβ1 (Kd = 1 nM). At least 10 splice variants of ERβ have been identified. 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55

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.
