What is finasteride made from?
Chemistry. Finasteride, also known as 17β-(N-tert-butylcarbamoyl)-4-aza-5α-androst-1-en-3-one, is a synthetic androstane steroid and 4-azasteroid. It is an analogue of androgen steroid hormones like testosterone and DHT.
Where is finasteride found?
The Type II 5α-reductase isozyme is primarily found in prostate, seminal vesicles, epididymides, and hair follicles as well as liver, and is responsible for two-thirds of circulating DHT. In humans, the mechanism of action of finasteride is based on its preferential inhibition of the Type II isozyme.

Is taking finasteride worth the risk?
Currently, studies show that finasteride is safe to use over the long term. For example, a study from the Prostate Cancer Prevention Trial of almost 19,000 men who had taken finasteride for seven years concluded that there is “little need to worry” about any long-term consequences from finasteride.
Does finasteride raise testosterone?
Finasteride blocks the action of an enzyme called 5-alpha-reductase. This enzyme changes testosterone to another hormone that causes the prostate to grow or hair loss in males. It will increase testosterone levels in the body, which decreases prostate size and increases hair growth on the scalp.

In the first 3 mo, testosterone increased hematocrit 4.13% (P <, 0.001). Coadministration of finasteride did not alter any of these effects. … We conclude that a higher-than-replacement TE combined with finasteride significantly increases muscle strength and BMD and reduces body fat without causing prostate enlargement.

A multiple cohort study with newly diagnosed non-metastatic prostate cancer showed that the use of ADT increased the risk of acute kidney injury (AKI) [6].
Can you drink alcohol on finasteride?
