How much testesterone is produced by the body??

How much testesterone is produced by the body at the fair age of 23-27 or higher? is it more or less than the amount of let's say a weekly or every 7-10 day shot of test enanthate? .......

Alright, that's it for the ranges. Hopefully this will answer a number of peoples questions about what is considered "normal" for a male.

thanks for the reply, i wish i could understand most of it, i know some, but some translation would help a bit to know if the regular shot of test enanthate or any other test taken at let's say 100-200mg/week, is that a higher/lower level compared to what ones body now produces at a older age 23-27 or even older....thanks

Here is a chart showing blood levels for an admistration of one 140 mg shot of test cyp or test enth.

thanks sundevil, so the base indicates the days and the levels they gradually decrease, is this correct? my other question which has not been answer is what the are the level of test produced in male body at around middle age 23-30, is it gonna be higher/lower than shot of injectable test every 7-10 days? i hope am making sense here... thanks bros

Hi Modizzle,

the Y axis shows multiples of Base testosterone level and the X axis show the number of days elapsed since the shot.

Chris

thanks sundevil, i understand the graph part of the inject... but my question still remains at....what the are the level of natural test produced in male body at around middle age 23-30, is it gonna be higher/lower than that of an injectable test ...i hope am making sense here... all i need to know is the comparison of natural body test production to that of an injectable..... thanks bros

I'll post what results I found here, but first, have a look at this funny article:

Here is some info from a site called get-back-on-track.com

Testosterone Production

Testosterone is the most important male sex hormone (androgen). In men more than ninety percent of testosterone production takes place in the testes. A considerably smaller amount is produced in the outer layer (cortex) of the adrenal glands.

An adult male produces about 6 - 7 mg testosterone per day. The normal blood level of testosterone fluctuates between 12 and 35 nmol/l. The amount of testosterone produced varies in the course of the day and blood levels can be up to 30 % higher in the early morning. This is the explanation for morning erections. Testosterone levels are usually at their lowest between 6 and 10 pm.

Testosterone production declines in the course of a man's life. On average, testosterone levels begin to decrease gradually after the age of about 35 to 40.

Testosterone has different functions in different phases of life.

In the unborn child it causes male sexual differentiation while during puberty it is responsible for virilization (masculinization).

In the adult male testosterone controls all sexual functions (libido, potency, fertility). In addition, it preserves the typical male build and appearance. It is important for physical health and performance and also has a decisive influence on mood and sensation of wellbeing.

You can see that an injection of testosterone is a lot more than what the average male produces--thus the shutdown of the testes.

Now, the important thing here is that this is all talking about the normal functioning male. If you refer back to the blood levels in mitch428cj's reply (260 - 1000 ng/dL -- I've also heard 300 - 1200 ng/dL), the average male falls in the middle of that--around 630 I believe. I tested low at 310 the first time and 194 the second time. A shot of 300 mg of test cyp brings my levels to around 1300 which then tapers off as in the graph sundevil posted (due to the half-life of test cyp). You can see that any injection is going to be way more than what your body would naturally produce whether you have a low hormone level or not.

thanks a bunch tonyKemp!!! that answers my question completely...The reason behind my questioning is that, if my body produces like let's say an avereage 6-7mg a day juust like tonyKemp explained above, is need for normal function, well am thinking if i just inject the moderate dose of 100-200mg/week that is higher than the normal body production, well if that is the case then it means that i can still gain a good amount of mass not as much as someone who is taking more than 200-1000mg/weekly. So higher level above normal body production would mean increase in mass... So comparison of a weekly body production lays in about or an estimate of 49mg/weekly @ 7mg a day, Compared to 100mg/weekly of injectable test would be doubling the normal body production right?.....

i wonder what it is for women then? lol

like 11mg a day is what im was told...hmmm

well that was an interesting read bro thanks, and thanks for the question.

I think that 49mg per week is very decieving. I've tried using low test doses and I felt good for a very short time and then felt like doo,doo. The only thing that I can contribute this too is that I felt good until my natural test shut down.

When I say low dose per week, I'm talking about 350mg per week. I cannot run an extended period on less than 500mg per week and expect to feel at least as good as normal. Maybe someone else can explain this scientifically.

your body operates on set levels of detection for amounts of chemicals in the blood stream, these levels are know as detection thresholds....Next the body has another set of measures in place to monitor any increase in levels...this measure is know as the JND or just noticable difference. The JND is the minimum amount needed for your body to notice a change in it's natural levels. So it is true that an individual may see decent gains off of a minimal cycle but when natural test production shuts down the levels of test in the body will automaitcally drop down to what ever is being put into the body....thus, you only have an inceased amount of est in your system for the over4lapping period of time which is generally durring the fsecond and third weeks. I have always combatted this by increasing my doses one the third week in order to make up forn the natural desrease in test levels that takes place. Even when running a minimum dose of 250mg per week your test levels are higher at the onset but when natural test production ceases you will eventually have gone from elevated to a lowered elevated state by increasing doses on the third week you are once again bringing levels back up to a superelevated level. EM this can explain why you feel good for the first few weeks and then not as good afterwords...hope i was a little helpfull

Very good explanation, thank you for that! This is also a good post for those getting blood work done to compare to the top of the thread.

In one of my bookes i read 7mg a day. But I Don't now at wat ages that is.

good info to know...really informative

so basically, (bare with me), taking a test injection which is less than what you produce naturally per week is only going to benefit you untill around week 3 I hope I am understanding correctly? so you won't have elevated test levels once your testes begin to shut down? does this mean that it is pointless to shoot 250 mg of test for any long period of time? sounds like you are prob hurting your gains in the long run unless you add another compound or up the dose

i guess i wrongly assumed that any extra amount of test was going to benefit you but it seems that this is the case for only a short time.

i believe as you age you produce less test...but shooting 250mg weekly will still have good levels in the blood till you shoot again after 7-10 days...Am on test e 200mg/weekly and i have gained so far 14pounds in 4 weeks...and i know most of it is water,...but 250mg every 3 weeks will mostly like shut you down depending on what test your are using....Long acting or fast acting...

well fill us in after pct and let us know how much you keep. I am intrested to know...

Oh i will,,, if you want to follow on my progress so far...just use the following link...
