Among the testosterone derivatives, and in no particular order, levonorgestrel , norgestrel , norgestrienone , ethisterone ,  gestrinone ,  danazol ,  tibolone ,   normethandrone ,  and norvinisterone  have the greatest androgenic activity,      while norethisterone and its prodrugs ( norethisterone acetate , norethisterone enanthate , lynestrenol , etynodiol diacetate , and quingestanol acetate )  have moderate activity.     Testosterone derivatives with low (but potentially still significant) androgenic activity include desogestrel , etonogestrel , gestodene , and norgestimate ,    while norelgestromin ,  noretynodrel ,    norgesterone ,  allylestrenol ,  and dimethisterone  appear to have negligible activity. Dienogest and oxendolone are unique among the testosterone derivatives in that they are potent antiandrogens.  
Reviewed by a non-active member of I ordered from the following: Dragon Pharma Enantate 400, Deca 300, Arimidex, and Dianabol 20. I have below how long and how much I ran of each product. I started out at 5'5", 170 lbs and ended at 200 lbs I saw major strength gains and picked up weight in no time. My appetite went through the roof and allowed me to devour roughly 6,000 calories a day while on cycle and still feel hungry. Everyone I go to school with noticed the difference in my body because I had started my cycle a couple weeks prior to school starting. It was pretty fun to receive the "Bro do you use steroids?" question during my whole first week of this semester. Can't wait to get my next shipment in from them.
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.
