hypogonadism, male
"I'm only 26 but was at the low normal range and exhibiting every symptom of low testosterone. It runs in my family on my father's side unfortunately. 

Within a week of taking it all of my mood returned to normal,  I'm no longer sleeping more than 7 hours and feeling well rested. I have a ton more self control and can easily diet and exercise. It gave me my life back basically.

Only side effect I have is raging a lot but it's manageable, especially since I have a punching bag here."
