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. 
Prohormones are precursors of natural hormones in the body, such as testosterone. They are often used as safer alternatives to anabolic androgenic steroids. Anadrole is not a prohormone, although it does have similar mechanisms of action that result in increased androgenic hormone activity in the body. When should I take Anadrole for the best results? According to CrazyBulk, it is recommended to take two (2) capsules with water approximately 20 minutes before breakfast. Use this product along with a suitable diet and workout program.
