What Are "Normal" Testosterone Ranges for a 28-Year Old?


If the doctor failed to specify male “E2 sensitive” testing the lab will automatically revert to the female E2 test. Your T levels are supposed to drop throughout the day, how fast thing happens is unique to the individual.

TT, FT, E2 and SHBG are pretty standard for a 4-6 week follow up labs after initiating TRT and at the 3 and 6 month follow up labs. These tests will tell you how you’re responding to treatment and unless you’re having problems (adrenal fatigue = low cortisol, thyroid issues) more test could be needed.

We see a lot of guys who begin TRT and experience underwhelming results, this is likely do to a weak lagging thyroid that can’t keep up with the metabolic rates that good T levels attempt to restore, the patient can feel even worse than before TRT.

Being in the normal ranges doesn’t mean you’re alright, if your body performs optimally in the 900 TT range and you’re at 400 range, that isn’t alright. This is what most doctors fail to understand, inexperienced doctors who are lazy non critical thinkers will fixate on lab numbers so they can get off easy and on to the next patient.


I really appreciate all of this information.
I’m gonna look to work with a Doc and address this.

Should E2 be addressed separately or would TRT bring up that E2 sufficiently?



We get our E2 from FT, is one is low the other is also low. Increasing your TT will increase FT therefore increasing E2. A few weeks ago I had high E2 symptoms, one could also say that my FT was high enough that it produced too much E2. Most would simply increase their AI dosage, only I’m not on an AI so decreasing my T dosage solved my problem.

I can be in the 700 ranges with no AI no problems, it’s only once I get into the 800’s is where I start to convert too much FT–>E2.


That makes perfect sense.

I really appreciate this deeper understanding. Looking in the wrong areas you can get the idea to get on T and use an AI to drop E2…turn out E2 needs to be in balance.

Again, really appreciate it…what am I looking for as a marker for ineffective thyroid, if I get on TRT and still feel like the same? THS bumping up above 2?


To get a complete picture of your thyroid you need every test possible, if you miss say rT3 which can block fT3 you’re not alright. Most doctors can’t run all these tests, not with insurance companies breathing down their neck to reduce costs and this is why Discount Labs exists.

Now you can walk into the doctor’s office and say hay doc look we have got a problem that would otherwise have been brushed under the rug by a doctor who just doesn’t care because he’s not the one suffering. I myself just can’t reach 98.6 degrees and have purchased Thyroid Support, most are iodine deficient.

Low E2 is dangerous to your brain, bone and joint health! Lots of bad thing can happen to you.


Brother I got my levels checked at 1 pm my level was 410ng/DL if I get it checked at 8 am will it be 550?


You not supposed to test past 10am, reason is your levels peak early in the morning and drop throughout the day, so testing later in the day is like counting your net paycheck after you have spent most of it.

Levels aren’t static, increase/decrease based on quality of sleep, diet, and exercise.


why would you ask this question? Can’t you just get tested and find out? why even play the guessing game when you have the ability to find out for certain?


So that means if one day I have 410 then it’s possible next day it’s around 700 ? Does it keeps changing ???


Brother it’s just that I don’t have much money to keep checking my levels on regular basis . I already have a level of 410 which I got at 1 pm so I just wanna if my level is already around 800 in the morning .


Your not going to get TRT with those numbers, you want higher numbers go to the gym and work out, eat healthy and get plenty of undisturbed sleep.

Your level can change based on lifestyle choices. You’re not too far down the rabbit hole just yet, you can turn it around. Ignore testing done after 10 am.


let me ask you this… if even your afternoon levels are not low enough to receive TRT, then what do you plan to actually DO with the information? Like, if you found out you were 450 or lower in the morning, would you proceed differently than if you found out they were 800? Seems like a non-issue, unless you plan to buy testosterone illegally depending on what number comes up for you.


Thanks for clearing my doubt mate . I am relieved :innocent:


Brother I want to ask about morning wood . I sleep around 2 am and wake around 10 am but when I get up early around 6 or 7 only then I notice morning wood and never around 10 am

@systemlord sir I don’t have sensitive e2 test in my country . I have male boobs . Sir how can I get my estrogen levels checked ?


You said right brother I am getting morning wood from 3 days continuously . I just added zinc and ashwagandha one tablet of both at bed time . And this is amazing :sunglasses:



This isn’t a normal ref range. I can show studies showing the mean test level for a 19-25 year old is 650-750, this range makes out the supposed mean level is supraphysiologic. Medical literature states a diagnosis of hypogonadism can be made off a TT level of 330 or below with symptoms of androgen deficiency, and these are relatively outdated guidelines. Your ref range is stating 190 is normal, most of these ranges are not based on any sort of clinical significance. I believe (although I’m probably wrong)) some labs legitimately use stars from previous people coming in for tests, in which case of course the results would be a low ref range as the majority of people getting their androgen status checked probably suspect low T

My ref range is like 200-750, I think of normal (for a healthy, lean young man not on a ton of meds with a healthy diet) to generally be like 400-1300


Yeaa but my body is perfectly working fine . I don’t goo to gym nor I eat testosterone boosting foods . Still I’m doing fine . 504 Ng/dl getting morning wood now . I’m out of this trt thoughts now. It’s my body natural level not taking steroids ever to go to 1000 level lol
