Drostanolone Enanthate or Masteron is probably one of the most interesting steroids used by athletes. It is primarily designed for the treatment of breast cancer patients to inhibit estrogen production. Estrogen is the hormone secreted by females that gives them their distinct gender characteristics. Maseril, the trademark of Drostanolone Enanthate is used in breast cancer therapy and is combined with SERM (Selective Estrogen Receptor Modulator). There was a decrease in estrogen levels among women who had gone through the treatment using this hormone. Masteron had become a favorite steroid among athletes and competitive bodybuilders. It is a very popular anabolic steroid. Masteron is a derivative of dihydrotestosterone or DHT, which restrains the conversion to estrogen through aromatization. It could be that its ability to inhibit estrogen from interacting with the aromatase enzyme or it blocks the receptor that binds the estrogen that causes these phenomena. Whatever the reason, because of its anti-estrogenic properties it blocks the conversion of free testosterones to estrogen through the aromatization. This makes Masteron a common inclusion in a high anabolic cycle. Since compounds used in cycles to achieve mass gain and strength have very potent testosterone content, Masteron is used to prevent the estrogenic side effects to take place.

Valproic acid was first synthesized in 1882 by Beverly S. Burton as an analogue of valeric acid , found naturally in valerian .  Valproic acid is a carboxylic acid , a clear liquid at room temperature. For many decades, its only use was in laboratories as a "metabolically inert" solvent for organic compounds. In 1962, the French researcher Pierre Eymard serendipitously discovered the anticonvulsant properties of valproic acid while using it as a vehicle for a number of other compounds that were being screened for antiseizure activity. He found it prevented pentylenetetrazol -induced convulsions in laboratory rats .  It was approved as an antiepileptic drug in 1967 in France and has become the most widely prescribed antiepileptic drug worldwide.  Valproic acid has also been used for migraine prophylaxis and bipolar disorder.
