test is synthesized from cholesterol. I don't know how it's done, but I know that is the process. There is a little info on how it's done in the body...how you synthesize it outside of the body I have no idea.
The synthesis of testosterone begins with the mobilization of cholesterol by the steroid acute regulator protein. The dominant steps involved in synthesizing testosterone from cholesterol are the formation of pregnenolone, 17--hydroxypregnenolone, dehydroepiandrosterone (DHEA), androstenedione, and testosterone. A less dominant pathway involves the formation of progesterone from pregnenolone, followed by 17--hydroxyprogesterone, androstenedione, and testosterone.[1]
Regardless of the pathway, the rate-limiting step in the synthesis of testosterone is the initial formation of pregnenolone from cholesterol. This step is catalyzed by the enzyme P-450scc (cholesterol side-chain cleavage enzyme) and is inducible by luteinizing hormone (LH) secreted by the pituitary gland. Once released from the testes, testosterone may be converted to dihydrotestosterone (DHT) in various target cells by the enzyme 5-reductase. Testosterone may also be converted to estradiol by the enzyme P-450arom (aromatase).[1,2]
