Basically my GH and Test levels are at the lowest ( in range ) for an active 21 years old is really worrying me.
This may not be a problem, anywhere in 'the range' is supposed to be fine. Also, this is one blood test ...
do you have any other tests from the past?
Free T is vastly more important and am assuming that 'Free Androgen Index' is just that. The SHBG reading would indicate this is so and matches what might be expected.
Estradiol is higher than I might expect for this level of SHBG (I am NOT a doctor) but in a very healthy range (CV studies indicate one should be between 20 and 30 pg/ml - you are 28.6). If future blood tests show this pattern, then you could increase T and Free T with low dose anastrozole without using AAS. But don't even think of messing with hormones until you understand what is normal for you ... and what is going on now if there is a problem
Also, T is highest when you wake up. So hormone blood draws should be drawn between 7 and 10am.
What time was your test done and how long had you been up?
Growth Hormone 0.064 mcg
GH is pulsatile with 15 min half-life. The only way to get an accurate reading is to take it every 30 minutes for a 24 hours ... a practice that is not done. It is not very useful otherwise. IGF-1 is what is useful.
i took are clenbuterol and ephedrine
These types of stimulants do have some hormonal effects.
How long had you been off these before your blood test? Clen, for example, messes with thyroid hormones. It is also has a "dopamine-releasing activity" so when you discontinue, there could be a period of lower dopamine. Low dopamine will absolutely increase prolactin, lower sexual function and mess with concentration. Whether this is your case is simply a possibility.
not a very manly chest
Do not understand this statement. This can't be a new symptom.
Do you mean pectorals seem smaller than you would like? Do you mean very little chest hair? How does it compare to your relatives? Prolactin reduces body hair growth and nail growth BTW. As for size, others on the forum would be better with advice exercise for chest growth. Have read that niacin can help here - if it is true, don't know why.
I have been suffering from decreased Libido, sex drive, ununderstandable headaches (diziness)
Is this since the stimulants or any time/event you see? Clearly these are negative changes and your age should not be a factor.
highlevel of prolactin
This is the obvious red flag and can cause some mild symptoms at that level. It is too low to indicate a tumor but low dopamine is likely if high levels persist. Prolactin lowers GnRH which will lower T. Your LH and FSH don't indicate a problem here, but they are pulsatile so its hard to know ... at least they are not tanked.
It will be important to repeat your test in a few weeks. Doctors never react to just one and neither should we. Be sure to include CBC, metabolic panel and lipids for your next one. You want to start building a record and establish your baseline as well.
