A 2006 study determined that 1-testosterone has a high androgenic and anabolic potency even without being metabolized, so it can be characterized as a typical anabolic steroid. 1-Testosterone binds in a manner that is highly selective to the androgen receptor (AR) and has a high potency to stimulate AR-dependent transactivation . In vivo , an equimolar dose of 1-testosterone has the same potency to stimulate the growth of the prostate , the seminal vesicles and the androgen-sensitive levator ani muscle as the reference anabolic steroid testosterone propionate , but, unlike testosterone propionate, 1-testosterone also increases liver weight. 
If you decide to try a topical Testosterone Medication for Testosterone Replacement Therapy , you can buy Testosterone Androgel® that is one of the better ways to treat testosterone problems. Androgel® is can be an effective way to increase testosterone levels. Androgel Testosterone is a clear, colorless and hydro alcoholic gel containing 1% testosterone. Androgel provides continues transdermal delivery of testosterone for 24 hours following a single application to intact, clean, dry skin of the shoulders, upper arms and/or abdomen.
Because the ultimate goal of a steroid cycle is to increase strength and muscle size, the associated spike in estrogen which accompanies steroids such as Testosterone is considered undesirable. In order to disassociate the two effects, two classes of drug are used. Medications such as Nolvadex or Clomid target the estrogen receptors. They make it more difficult for the estrogen to exert it’s influence within the body thus allowing the testosterone to act more freely. The second class is aromatase inhibitors such as Femara. They target the aromatase enzyme itself in order to prevent the production of estrogen in the first place. Sometimes, it’s not always clear which option you should go with or even what the differences are between the two. Lets clear that up a little.
