SAA's act as very weak molecular androgens that bind to the androgen receptor and activate it with a lot less androgenicity therefore effect on AR signaling than something such as endogenous testosterone or DHT would be doing.It has be close to identical otherwise how would SAAs bind to ARs?
So basically SAA's are androgens but just weak ones, therefore they act as antiandrogens BUT can also possess androgenic properties especially in an androgen depleted environment. This has been demonstrated in prostate cancer.
AR signaling is only present in breast tissue, prostate, skin, hair follicles, and testicles (but testicles only require 5-10% of average male levels of ar signaling for spermatogenesis). So having low AR signaling is considered a good genetic trait if anything. The only downside to low AR signaling is gyno.One would f*** himself up really hard if he tries to block all AR signaling ... More so while not taking estrogen. Our bodies aren't supposed to be without AR signaling, right?
