18 and 321 Testosterone Level?

Im 18 and recently had my testosterone levels checked for the second time. I was put on Phentramine by my doc for weight loss because I gained 60 lbs in about a year and was up to 5’9 and 280. He did a blood test to check cholesterol and said he wanted to check my testosterone and see what it was and it came out at 319 at about 6 in the afternoon.

Now I dont mean to give you all my life story but I started puberty young and was stronger in 5,6,7 grade than all my friends and then in 8th grade I started to kind of lose strength and muscle size and noticed friends were getting bigger. Also 8th grade and through my 9th grade summer I got very very depressed and required hospitalizations and medication for depression.

Im stable now and Tuesday went to have my levels rechecked. They were up to 321 in the morning first thing. I was wondering if that is normal for an 18 year old male? Ive stopped playing football because im noticeably not as strong and I dont have the motivation to workout or even have sex with my girlfriend. Ive had problems keeping an erection and my libido is almost dead. Any help or suggestions would be great.

Thanks guys.

No it’s not normal. Your T is low esp for your age

Read the advice for new guys sticky.

I beleive I am going to see an endocrinologist. I have no idea what to expect. Do they give me shots or gel or pills or all of the above? Im lost.

Your moving way to fast… Breath brother.

You have alot to learn and I don’t recommend jumping on shots without finding out why your T is low.

It’s a life log commitment and not very much fun for some at all.

Please read the stickies starting with advice for new guys read them carefully an then read them again.

We see a lot of guys in your age group with these issues. Do not attempt TRT now, you need to find the cause.

There is a lot of ground to cover. Here is my canned response:


This is standard advice maintained here:

There is a huge amount of knowledge in the stickies. Please study these. Start with the advice for new guys sticky.


There is a lot to read there, so read carefully. There are suggestions for things that are root causes of low testosterone [T]. Low T is a symptom, not a root cause itself. But low T itself is a root cause of many of the symptoms one experiences. Note that other things cause the same spectrum of symptoms, so do not have T tunnel vision. Many docs are guilty of that and they only treat the symptom [low T] and do not attempt to find the real problem. If you go to a clinic that specializes in low T, you will get T tunnel vision for sure.

Post info about yourself as suggested in the above sticky. We need labs, almost all of your labs, not just hormones. We also need the lab ranges.

We see a very high number of thyroid issues in the population of guys that show up here. So there is a strong focus on that. Most people are iodine deficient to some degree. Your history of iodine intake from iodized salt and vitamins that list iodine is important. If you become iodine deficient, the RDA [recommended daily allowance] is inadequate for recovery of iodine stores. Please see the thyroid basics sticky for more information.


You do not want to suffer from subclinical hypothyroidism or get Rx thyroid meds to treat iodine deficiency.

If you are injecting T or contemplating that, read the protocol for injections sticky.

There are stickies for finding a TRT doc, estradiol [E2] and lab work.

Do not place your history or treatment details in the stickies! That belongs in your thread. Keep all of your posts in your thread so we can have a clear picture of your situation and needs.

Can you also please provide a detailed overview of all your symptoms. Clinical evaluation is just as important as lab work in identifying what the possible cause may be.

The advice for new guys sticky has a list of possible symptoms you may have. Please indicate if you have any of these symptoms, and how severe this symptoms are.

It will you help you understand whether or not it’s an adrenal problem, pituitary problem, thyroid or testicle problem. If you have adrenal or thyroid problem TRT will not solve your issues.

If you have any questions with direction here is the place to put it.
