TESTOSTERONE
The primary androgen is testosterone. Nearly every synthetic AAS (Anabolic / Androgenic Steroids) are chemical forms of testosterone and therefore a lot of the characteristics apply to them likewise. But not all! Testosterone has 2 distinct features or effects:
1. it has anabolic features (tissue making) which express themselves as Expanded and accelerated muscle tissue growing which directs to quicker recovery time after training, illness, and hurts, and to a faster "regeneration" of the body. Its because an anabolic response directs to the promotion of protein synthesis and tissue repair or growth.
2. androgenic features or effects which are generally named as secondary man features that raise sexual behavior, libido, growing and maturing of the penis, body hair, beard growth, deeper voice, aggression, and formation and maturation of sperm. And of course, Expanded production of the sebaceous gland and pimples.
It's primary to realize the difference between free/active testosterone and bound/inactive testosterone/AAS . Bound testosterone is passive because it's bound to Sex Hormone Binding Globulin and to a small degree, albumin. The sex-steroid atoms are bound by SHBG held in the blood, which keeps them from fitting into their receptors. Free (unbound/active) testosterone is capable to transfer its Features because it fits into receptors. Bound testosterone matches around 97-99% of Full testosterone circulation while free testosterone matches 1-3% of entire testosterone. That doesn't sound a lot, but still 0.1 - 0.3 mg of free testosterone has a Batch of single separate molecules. And 1 molecule may activate all receptorsite it attaches to.
Man have a entire testosterone reference range of 225-950 ng/dl. Free testosterone reference rate for man is 1-3% of the entire testosterone reference range.
Womans have a entire testosterone reference range of 14-76 ng/dl and a free testosterone reference range of 0.5-1.8 ng/dl.
Bound testosterone may be loose due to metabolic requirements and another steroid molecules. And both endogenous and exogenous Anabolic/Androgenic Steroids could react differently to SHBG. Because of this cause a few synthetic AAS could change the ratio for some another free and/or bound androgenic levels.
