At its core, illegal Testosterone for sale can be in the form of pharmaceutical grade Testosterone that is the same grade of product manufactured by pharmaceutical companies and dispensed in pharmacies for medical purposes, or the Testosterone can be of underground laboratory (UGL) origin, which tends to be the more common form of Testosterone for sale these days. Pharmaceutical grade Testosterone for sale on the black market is generally self-explanatory, as they are legally manufactured products by pharmaceutical corporations that have been diverted for illicit sale on the black market . Testosterone for sale in the form of UGL products are Testosterone products that are manufactured by illicit and illegally established laboratories that are often set up in a home, running in a kitchen or basement. These products are manufactured exclusively for the purpose of sale on the black market to those who wish to use them for performance and physique enhancement. Because these products are manufactured illicitly, they can vary greatly in quality, sterility, and purity, but they are highly affordable as these types of Testosterone for sale can be a fraction of the cost of pharmaceutical grade products. Black market Testosterone for sale purchased through the internet can originate from outside the country, or be a domestic-run operation within the country it is being purchased in.
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).
