Got my HGH results. What does these numbers mean?
Just got my results from my hgh test.
Less than 0.5 mu/l.
I've done some research and cannot establish if this is low or not. I have yet to see the doc, I got the results over the phone.
Any help greatly appreciated.

What is your age? Have you been running HGH, or was this just a test of your natural levels? Also, have you been running IGF-1?
Need this info before I can comment.

I still cannot make sense of the way the test results are expressed,
but a normal result of a test for an adult male is less than 3ng/ml (nanograms
(10-9 grams)per milliliter). If your test results are 0.5ng/ml, then those levels are normal, not low. Let me know if there is anything more that you need.

I just found an important study that expresses GH concentrations in u/L.
The normal range for men is 500-1500U/L in healthy men ages 20-40 years
old. The results in the question were 0.5mU/L, which translates into
500U/L. In the normal range.
If you are freaked out about that being low, you should know that it is difficult
to measure GH. It is a pulsatile hormone, which means it is released
in a rhythmically, not constantly. It is also released during the early
stages of sleep. As you probably know, a test for plasma IGF-1 levels
is a good way to determine GH levels, because GH stimulates the production
of IGF-1. IGF-1 levels levels change slowly, which is why it is a
good test in addition to a GH levels test.
Since normal levels of GH can vary widely, other tests may be done to
confirm the results of a GH test. Additional tests can determine whether
low levels of GH (which can be normal) mean the pituitary gland is not
* Insulin -like growth factor 1 (IGF-1) blood levels are commonly
evaluated along with GH levels. A high level of IGF-1 along with a high
level of GH is almost always diagnostic of acromegaly. In this case,
magnetic resonance imaging (MRI) studies should be done to evaluate the
pituitary gland. For more information, see the medical test Magnetic
Resonance Imaging (MRI) of the Head.
* The growth hormone suppression test (also called the glucose loading
test) measures the level of GH in the blood before and after a person
drinks liquid containing a large amount of sugar (glucose). Normally,
the amount of GH drops to less than 1 ng/mL after drinking the glucose.
Levels of GH that remain high may indicate acromegaly.
* The growth hormone stimulation test (also called the insulin tolerance
test) measures the level of GH in the blood before and after insulin
is given through a vein (intravenously). Normally, the amount of GH increases
after the insulin is given (in children the level should be more than
10 ng/mL; in adults it should be more than 7 ng/mL). A GH level that
does not increase may indicate a GH deficiency. Growth hormone levels
of 0 ng/mL can be found in people with GH deficiency as well as in people
with normal pituitary function. For this reason, a growth hormone stimulation
test can help diagnose GH deficiency.

0.5 mU/L is very low for you.
