In general, the normal range in males is about 270-1070 ng/dL with an average level of 679 ng/dL. A normal male testosterone level peaks at about age 20, and then it slowly declines. Testosterone levels above or below the normal range are considered by many to be out of balance.
Is 313 a low testosterone level?
Testosterone levels peak at about the age of 20 years, and then the testosterone slowly declines with age. In younger men, the average testosterone level is in the range of 650. When the testosterone is under 300, that’s when we would consider an adult male to have low testosterone.
Is 300 considered low testosterone?
Normal testosterone levels According to recent guidelines from the American Urological Association (AUA), a testosterone level of at least 300 nanograms per deciliter (ng/dL) is normal for a man. A man with a testosterone level below 300 ng/dL should be diagnosed with low testosterone.

Generally, most experts would agree that a total testosterone level less than 250 ng/dL is considered low, whereas some experts endorse a higher level of around 350 ng/dL as the lower limit of normal.
What is a good testosterone level for a man over 40?
Most doctors agree that a “normal” reading falls anywhere between 300 to 1,000 nanograms per deciliter (ng/dL). About 40% of men over age 45 will have levels that come in below that range. But a low reading by itself isn’t enough to warrant alarm.

Is testosterone an ester or ester derivative?

First of all, there is more than one form of testosterone: One is bonded with sex hormone binding globulin (SHBG), which is the most common type and makes up about 65 percent of total testosterone. The testosterone attached to SHBG typically cannot be separated from the hormone, so this T is not considered to be bioavailable.
