Is it normal for a 14 year old male, who started puberty at 12, to have adult levels of testosterone? My results were about 784.63 ng/DL, which I thought were quite high for someone my age considering the fact that I have a faint mustache and small amounts of body hair.
Here is a chart of typical testosterone levels in boys:
|0 to 5 months||75-400 ng/dl|
|6 months to 9 years||Less than 7-20 ng/dl|
|10 to 11 years||Less than 7-130 ng/dl|
|12 to 13 years||Less than 7-800 ng/dl|
|14 years||Less than 7-1,200 ng/dl|
|15 to 16 years||100-1,200 ng/dl|
|17 to 18 years||300-1,200 ng/dl|
|19 years and older||240-950 ng/dl|

The broad ranges are because boys enter puberty at different ages. But what I want you to notice is that during adolescence your testosterone levels are often higher than your adult levels.
