I have been on 50mg of Natrol brand DHEA since 38, I am now 56 (so guess I AM that long term test guinna pig they seem to be looking for) I have NO health problems at ALL at this age, and can still outrun my 20 year old son, no blood pressure or colesterol problems, and am 5’10” at 145 (still wear the same pant size I did in high school. Personally, I swear by this stuff, and can definately TELL when i miss a few days (i have tested this theory my self many times through the years just to be sure it wasn’t the plecebo affect.. trust me, it isn’t. I still have a full head of hair (NO loss), can still keep up with 4-5 times a night in bed with NO assit, and am constantly told i look 10 to 15 years younger than i am……….and still FEEL 30 ! It someone is looking for a test subject, i’m your man ! 🙂 I’ll never stop taking it, i don’t care WHAT the research says are side affects..
Some studies do not report back significant improvements in insulin sensitivity have used 50mg daily for 3 months in otherwise healthy overweight aged men with low (less than 1500ng/mL) DHEA; DHEA did not even trend towards significance, and appeared to have no directional effect.  This lack of efficacy resulting in no trend towards significance has been noted elsewhere with doses that should normally work.   In post-menopausal women where DHEA would not show efficacy, the combination of DHEA and mixed exercises did not create efficacy of DHEA. 
You were 100% correct. DHEA is amazing. I have been on it for only 9 days and I feel wonderful. I purchased Finest brand and I am starting off at 25 mg. The only side effect that I have felt,is that I am a little over emotional during the middle of my cycle. But honestly, I don’t care I have felt so wonderful for the past 8 days that it is worth a little crying during a Hallmark commercial.
And as far as my sex drive, WOW off the charts, that is why I had to drop it down to 25mg, because at 50gm I couldn’t leave the house or the bedroom for that matter …
I did find that it works best 1st thing in the morning before my workout,(empty stomach) because I had too much energy when i was taking it before bed. Does this sound correct?
My muscles feel tight and strong and the energy level is fantastic……
Keep up the great work.
