Natural test levels

**Beroo** · 10-09-2012, 04:38 PM

I know there highest when your young but I'm 19 and wondering if in about 5 years I should expect my testosterone levels to be at there highest, a bit lower than now or about the same. I'm natural, and this is also assuming I will be natty for the next 5 years, no cycles. So I'm basically wondering if they peak at around 18 or 25?

This greatly depends on the individual however it is accepted that during youth (ages 14-20), free testosterone levels are at their highest.

The Endrocrine system upregulates hormones up until the age of 25 or so. Then it levels out and starts to downregulate hormones. Your metabolism slows, and after 30 your test levels decline between 1-3% a year.

youngsters should keep in mind that this is a natural process but there are no absolutes. a 20y.o. kid who smokes two packs a day, drinks a few beers, eats fast food and stays out all night can easily have less total and free test than a 40 y.o. man who understands and games the system.

Does alcohol abuse at a young age (binge drinking once or twice a week) say from 15-22 have a negative affect of testosterone production? Any studies that back up either side? Always wondered if my drinking was a contributary cause of my low T.

and from wiki...

http://en.wikipedia.org/wiki/Alcohol_and_sex

"Men's sexual behaviors can be affected dramatically by alcohol. Both chronic and acute alcohol consumption have been shown in most [3][4][5] (but not all[6]) studies to inhibit testosterone production in the testes. This is believed to be caused by the metabolism of alcohol reducing the NAD+/NADH ratio both in the liver and the testes; since the synthesis of testosterone requires NAD+, this tends to reduce testosterone production.[7][8]"
