natural test levels

Although tis Q has probably been answered before, I couldn't find the answer through searching...

What is the normal range of Test in the male body? I know it is higher around puberty, and lowers as you get older. But what does a "normal" range look like? :unsure: I'm 25, if that helps.

On a related not, how many MG of test do you produce a day? :scratch:

I'm trying to figure out the avg break even point for taking test.

Example: If people naturally produce around 40mg/day, then injecting 250mg/week would be counterproductive because of natural test supression.

Thanks Bros,

Bioavailable- 19 years and older: 130.5-681.7 ng/dL


Free Test-• 19 years and older: 47.0-244.0 pg/mL


T. Test-20-39 yrs: 400-1080 ng/dL

Link to some info

thanks for the quick response!

im 21 and have 250 ng/dL bio avialable....thats pretty bad eeing i should be at 400?

i also drank the night before the test, i wonder if it affected bioavial :unsure:

I don't really get what ng/dL means. It's like comparing apples to oranges. How do I translate Pheedno's # into plain MGs?

ng/dl is nanograms per decilter
nanogram is 1-billionth of a gram
decilter is 1-tenth of a liter

I hear its 70mg/wk for the average young male..but Pheedno you got me confuckled on that um..measurement chart maybe :unsure:

Ok, let's see if I can decypher it

if 1 nanogram = 1/1,000,000,000 g => then

1 mg = 1,000,000 ng


Then, if 1 deciliter = 1/10 liter => then

1 dl = 100 ml

Does that seem right?

I'll go take a shower and shoot 250,000,000 ng of test E and 200,000,000 ng of deca in my ass. Maybe that would clean up my brain.

I'll try to convert it under one common denominator when I get back - so, we can compare apples and apples. ===== BTW - Good read, Pheedno - I was looking for this kinda info.

dl conversion is correct.


ng looks right

First off, Pheedno, what are those numbers referring to. Is that the total amount present in the bloodstream at any one time or the amount produced in one week?

If I do this conversion correctly..this is what I got for the Bioavailable testosterone, if the subject has 500 ng/dl..then he has .005 mg/liter of blood at any one time. Since, there are 5.6 liters of blood in the average human, that would mean that there would be .028 mg of bioavailable testosterone at one time. Jay, is that what you got?

For Pheedno's range of the total testosterone, I got a range of .0224mg-.06048mg.

Again, I wish I knew whether he meant the total testosterone at one time or the amount produced in a week. I think he means the amount at any one time, because if it were the latter, the amount of testosterone that the average bodybuilder injects would be astronomical in comparison.

It's at the given time. And ever varying as well so I don't think a accurate definitive number could be derived unless frequent testing was done.

Ok guys, I'm going to do some research on this and I'm going to see if I can figure out what the amount of testosterone produced per week would be.

Thanks Pheedno for answering my question.

I'll get back to you.

I just read the links in that study - this is what they are saying -----
those numbers are the concentration of Free test in the system at any given point of time.

" The concentration of Free Testosterone is derived from a mathematical expression based on constants for the binding of Testosterone to Sex Hormone Binding Globulin."

They way I see it - you can't derive the amount of Test produced from this info without knowing the constants, the duration and reproduction data.


I had a natural test production table bookmarked - but, I can't find it. (actually, it was a link from one of the threads here)

lol..Im going to stick with my 70mg/wk...atleast thats what was said a long time ago before i came back on here so much

70mg/wk - is within the range......

I'll post the link as soon as I find it - I'm still looking for it.....


PS Keep in mind ---- 250mg /week injected does not equal having 250mg/ week test throughout a cycle - it would take many weeks of 250mg injections to saturate to 250mg/week level (by the time it gets to 250 level - your cycle is over)

Interesting..but I have friends who have done just 250 a week and made good gains, how could this be so?

Because it's still a substantial increase from natural production

Thanks, kinda what i was thinking...an increase but not actually a full increase

well, 250 mg is a 350% increase from 70 mg. That's a pretty big bump in your hormone levels!

That's the problem --- you can't look at it this way.

The oversimplified way to look at it:

week 1 -- inject 250 test e (half life week 3 = 125) absorbed from 30 to 60 (let's say approx 60 = 125 / 2)
Week 1 -- natural test = 70 (minus what's shut if enough test added)
Total week 1 = 70 - what's shut down + what ever absorbed (about 60mg) approx 100 or less (just a guess)

Week 2 -- inject 250 test (half life week 4 = 125) absorbed 60
natural test let's say 20
60 from week 1 (second half = 125/2)
Total week 2 = 20 (natural) + 60 (week 1) + 60 absorbed from week 2 injection. = 140

week 3 --- inject 250 - absorbed 60
Natural 0
from week 1 = 15
from week 2 = 60
Total for week 3 = 15 + 60 + 60 = 135

week 4
natural 0
injected 250 absorbed 60
from week 1 = 8
from week 2 = 15
from week 3 = 60
total for week 4 = 143

Week 5
injected 250 absorbed 60
From week 1 = 4
From week 2 = 8
from week 3 = 15
from week 4 = 60
Week 5 total = 147

week 6
injected / absorbed 60
from week 1 = 2
from week 2 = 4
from week 3 = 8
from week 4 = 15
from week 5 = 60
Total week 6 = 149

Total week 7 = 151

tatl week 8 = 153 etc.


Tese numbers are WAY off the accuracy - but it illustrates the amount injected vs. amount you have

So, 250 mg is a 40% to over 100% increase (a few weeks into the cycle) from 70 mg -- wich is still a tremendous bump -- enough for a lot of people to grow extra.

I agree with your reasoning Jay, except for the fact that you are assuming that the average testosterone produced per week is 70 mg...which, as of right now, you do not know as a fact.

But nice post though. :)

absolutely - 70 is used for illustration only

Good point.

I'm still looking for the bookmark or the post where the natural test levels ranges are listed.

bump, and good explanations and discussion by all. Sometimes I rush to read the lastest posts and it doesn't sink in until after I have posted my reply. Oops! As of right now, I'm still sticking with the first test cycle of 250mg/week... unless RJs resources state natural test production is much higher than 70mg/week. I made small gains off of 25mg winny/day, so I'm thinking 250mg test/week should give me 10+ keepable lbs.

I'm a dumbass --- This morning I edited my calculations in the previous post a bit - I realized I used the wrong #'s for the week preceeding the injection (I used 1/2/2 instead of just 1/2) - it changed the #'s a little bit, but the principle is the same.

That's more of a calculation error - didn't change the outcome that much. - now corrected.

BUMP. Jay, did you figure out a range (in MG) of natural test production per week?
