So of course am going to make sure my boys have baselines.
He just turned 16. According to Dr he is in tanner stage 4. His t number just seem low esp if in tanner stage 5.
I know as you growing Numbers may not be stable. I do have 2 16 year olds interesting what his will be. I’ll post soon.
Thoughts?
Good albumin was actually 5.1 in a test he did a month ago. I’ll recheck calculator
Testosterone levels peak around 20.
So you think his levels are fine and should be on the way up?
Correct.
I will update this thread hopefully in 1 year and post 17 year old labs. I expect they would double. We always say we want the levels of a 18 year old so we will see a real case.
Btw boys are fit and athletic.
I will also post his twin Shortly
This is something I plan to do with my son as well. I feel like I was low well before I ever checked, and I know my dad has been low t for a while and never done anything about it. So, might as well be proactive.
On the right track. I plan on testing my child in his teens, just to have proper baselines. He shouldnt have to walk this earth with no clue of his health. Good work
This is great. Wish I could go back and get labs at 16-22. Good also to see, like you said, what a healthy 18 year old level actually is now
I see what you did there 
Agreed. I’ve seen youtubers in great shape post labwork with TT in the low 400-600ng range, and some in the 900-1000ng range. All look fit, like bodybuilders. The TT is only one factor.
I saw one guy, your nemesis, let’s say, post a video with his 17 year old son where he postulated that because he was fit and athletic, his TT must be high, and if his TT was high then his e2 was certainly high, so the video premise was “my 17 year old son feels great with high estrogen!” Total nonsense, and he didn’t get any lab work to back it up. My comments on that video got me banned from their group lol
So here is his twin brother.
Total t 409
Direct free t 15.3
Shbg- 14.3
Lh 4.4
FSH 2.3
Albumin 5.1
Other son posted higher in thread:
Total t 346
Direct free t 14.9
Shbg- 15.6
Lh 4.2
FSH 2.1
Albumin 5.1
My son is bragging already that he has more than his brother
Do you have a NINE inch erect penis?
WHAT!
Relatively speaking, how developed are they for their age?
Late bloomer, normal, above the norm?
These levels aren’t bad for 16, very wide discrepancy regarding “normal” at that age. If they’re 17+ and you’re looking at say… Sub 320ng/dl you MIGHT have a problem if they’re clinically Symptomatic
And another wonderful lesson: “gotta pay to play!”
The reality is that he will probably raise those levels until he´s 21. He´s still growing ! I mean, both of the kids 
But, the question comes : what if that is not the case and their best testosterone levels won´t be that much better than 400 or 500 ? What if that was our case when we were younger ?
By all means, I want to believe I had better testosterone when I was 19 than now at 40. Chances are this is 200% correct. But how much better were they ? And for how long did those levels last?
This also makes me think that not all of us may have had good T levels in the past. Did we ? Perhaps some of us did, but probably not all of us. While on TRT, maybe it won´t be that “mandatory” to reach the maximum of the normal T range to make it work? Since most of us don´t have baseline levels to compare, I can be wrong, but there´s a change that too many have higher levels on TRT than they had in their late teen days !! I wish I knew what were my references, because they worked for me in my late teen days and that was the best i´ve ever felt.
I´m not on TRT, but I wish i had T level references from those days…
Very interesting topic to follow !
Their SHBG was low, both kids had FT near 15ng, which is pretty decent. At least, I felt good at 15ng FT, but shoot for 25-30ng just for performance. I imagine as they get older that SHBG will go up
Totally agree
Not really, T levels usually peak during late teens, say 17-19.
People drastically overtime these kind of events (when do kids stop growing, when does pubertal induction occur/when does puberty finish). Aside from brain development, physically speaking most 18y/Olds are “adults”
Now that we are adults in our 40s or 50s without baselines to compare, the only thing we´re left with is good judgement and the minimum effective dosage for symptom resolution should we ever come to suffer from any associated low T symptoms. At least, if I ever start TRT that will be my motto.
If we have references, IMO we shouldn´t exceed them and try to work around them first. that´s what I´d do if I found out I had 400ng/dl back then. That´s what they are : references.
But we don´t have such references, so…again, good judgement is key. And also good eating habits, sleeping properly, exercising (mainly with health in mind, not performance), etc, will surely help with the whole process to makes us feel good on a daily basis.
Changes happen to our body and condition as we age and other life and aging factors play their role on the equation, specially in our mind.
That graph you posted is very interesting. I can be wrong, but while converting nmol to ng we can see that 500-600 is a good reference for a normal male individual. I wished the participants in the 15-21 was bigger ! But the main picture is there. Perhaps useful as a reference even though we´re all individuals.
