In July 2011, FDA began a pilot program to notify people of drug recalls before they are classified in an effort to expedite notifications of human drug product recalls to the public. FDA is now able to accomplish the goal of expedited notification within the Enforcement Report. These recalls are identified within the Enforcement Report by the label of “Not Yet Classified” in the “Classification” column. It is also possible to search the Enforcement Report for these “Not Yet Classified” recalls using the filter drop down menu. Therefore, as of September 15, 2017 FDA will discontinue the pilot program, and will no longer post drug recalls that are pending classification on this webpage. To see posted recalls that are pending classification go to the weekly Enforcement Report.
Neural injections of Bromodeoxyuridine (BrdU) were applied to males of both groups to test for neurogenesis . Analysis showed that testosterone and dihydrotestosterone regulated adult hippocampal neurogenesis (AHN). Adult hippocampal neurogenesis was regulated through the androgen receptor in the wild-type male rats, but not in the TMF male rats. To further test the role of activated androgen receptors on AHN, flutamide , an antiandrogen drug that competes with testosterone and dihydrotestosterone for androgen receptors , and dihydrotestosterone were administered to normal male rats. Dihydrotestosterone increased the number of BrdU cells, while flutamide inhibited these cells.
It shall be noticed, that in men, approximately 5% of testosterone undergoes 5α-reduction to form the more potent androgen, dihydrotestosterone (DHT), also known as androstanolone. From another side approximately % of testosterone is converted into estradiol (the primary female sex hormone) by aromatase an enzyme expressed in the brain, liver, and adipose tissues. Hence, don`t forget to take precautions to avoid respective side effects. Thereof we recommend to perform blood works and take aromatase inhibitors on cycle (if required, anastrozole preferably) and SERMs (clomifene, toremifene) during post cycle therapy (PCT).
