If you get real tribulus it manipulates the mind to creat mor SH hormone which then helps your boys work harder.
ZMA major atribut that causes elevated test is the theory that the average man with workouts and average diet takes in a insufficent Magnesium total for the day. Do by increasing magnesium intake it helps the body produce more hormones. Just like if you eat like **** and take a multivitamin. No doubt it will help
Now we all know that you grow when you sleep so going into a deeper REM state while sleeping will increas all sorts of hormones including GH. ZMA does this by adding Meletonin. A 6 HOUR SLEEP period will seem like 8, at least for me.
