The Peak for Testosterone Enanthate is about 24-48 hours after the injection.
The Trough (lowest level) for Testosterone Enanthate is just before the next injection.

Obtaining both levels will give the range of testosterone one's body is exposed to.
This is helpful to see if a person is within a good therapeutic range.

The shorter the intervals between injections, the flatter the range will be.

Large variations between the peak and trough can be a problem because there can be large changes in DHT and Estradiol levels - contributing to problems such as weight gain, acne, hair loss, and hot flashes. Hot flashes occur when estradiol levels drop quickly - they are withdrawal from estrogen.

Large peaks of testosterone may also result in large amounts of DHT and Estradiol being made. When Estradiol is made from testosterone, its peak levels last much longer than testosterone itself - resulting in a larger exposure to estradiol even as the levels of testosterone drop.

Testosterone Enanthate usually has a half-life of about 7-9 days. This results in a good total testosterone level (e.g. 700-900) at a dose of 100 mg a week. The half-life varies though depending on the person's ability to metabolize testosterone enanthate and testosterone.

In some men, the half-life of Testosterone Enanthate is much shorter. For example, in some men, the half-life is around 4 days. To achieve a total testosterone of around 800, such a person would need about 200 mg a week.

Given a Testosterone Enanthate dose of 200 mg every 2 weeks for an average hypogonadal male, the total testosterone curve shows a peak of around 1250 ng/dl approximately 24-48 hours after the injection, 1000 ng/dl around 4 days after the injection, 800 ng/dl 7 days after the injection, 600 ng/dl 10 days after the injection, and baseline about 14 days after the injection.

A way to tell what the half-life would be is to give the person a 200 mg dose then measure the total testosterone approximately 4 days or 7 days later. If the level is significantly lower than the average male dose curve, then the half-life is going to be shorter.

For example, I have a patient with a level of about 600 ng/dl 4 days after the 200 mg injection. This is about 40% less than the expected 1000 ng/dl seen in an average person. He has a very short half-life for testosterone enanthate. One could argue that his half-life is about 3 days (since 600 ng/dl is about half of the peak of 1250 ng/dl 24 hours after the injection). His body quickly destroys testosterone. He needed a 200 mg a week dose to achieve a trough blood level of about 800 ng/dl. It was best to dose this 100 mg twice a week to maintain an even blood level, avoiding a roller coaster effect, given the very short half-life of testosterone and testosterone enanthate in his body.
NOW thats the kind of reply i am taking about!!!!!!
THANK YOU so much !!!

Firstly I am not judging you.
I was questioning the amount of testosterone you were taking, as for many this will cause supraphysiological levels of T and eventually cause undesirable side effects, unless you are one who uses the exogenous testosterone as described by Marianco above.

I was also pointing out that many guys hop on to HRT therapy before really finding out what the problem is and thus being on testosterone for the wrong reasons.
It can be a diffcult path, and if natural function can be restored this can be by far the best way to go, ie a restart protocol can work for some guys.
If your condition is such that you have no choice but to take testosterone, then of course this is what you must do.

No problem.
Well, if you have tried the hCG and Clomid tests, perhaps yes, you will need HRT.
Marianco's excellent post should be of some help.

Sounds like you might be in Australia. If you need any further help and you have msn, my messenger contact is [email protected]. I have had a few years experience with dealing with this HRT stuff!

Cheers mate.

For the 22 yrs. that I have been on TRT I had to do a lot of T to get my levels up and my body used it up fast dam fast. At one time I was on 10 grams of Testim and doing 200mgs shots every other week to keep my levels up.

I think today I now know why this was being that I am not primary and now told I am Hypopituitary all of the things that I was low noraml on we are now treating DHEA, Cortisol and so on. Now my Total and Free levels are up so high we have had to cut my dose way back. So treating the other problems my body is not using the T meds up so fast. I could remember getting sick with a bladder infection and my T levels would drop, when my dad passed away I crashed my Dr. was giving me 200mg shots every week to keep my levels up. I feel if other things are off or wrong your body eats up T meds very fast just like Dr. marianco said.

As you are just 28, has the reason for your low testosterone been determined?

The doctors are not altogether wrong... stress and a diet low in fats and too much training can lower your testosterone levels significantly.
Hormone replacement is a big decision especially at your age, It should be an absolute last resort as it is full of difficulties and is never as good as your own natural function.
I am 24 years old with T levels prior TRT in the low normal range due to low caloric-fat nutrition and stress, psycologic or physiologic.I changed my diet eating even 200 grs day fat but testo didn't go above 400,so i went on TRT.Or the tetsts seemsto respond like HCG stimulation test and stimulation with synthetic LHRH(relefact),finding that the problem is hypothalamic(gnrh) cause all of my hormones are low like thyroid,IGF-1,DHEA,leptin(extremely low),but not cortisol.
What i supposed to do if i cannot get my levels to 800 and cause i am 24 coming to 25 i must not leave my life and wait until get old.I think when you are young ,in age,you are supposed to live as young.

Testosterone levels are highest early in the morning and lowest late at night.
