works great

Posted by Reviewer2374757 on Nov 09, 2008

Taking for multiple reasons including Lyme Disease, ED, memory problems and depression. Does definitely bring blood to extremitys. Not sure of the root of my circulation problems but this is working. ED is fading after about 2 weeks of 3 pills per day. If my fingers and feet can stay warm this winter I would be amazed and memory is improving but I am taking Vinpcetine and Huperzine A so not sure who gets the credit.

Lets just say that with this product, natural circulation will be restored and you won't need male enhancement chemical prescriptions! My husband had a problem, now he doesn't.

i started out taking two of these a day along with my acetyl L carnitine when i noticed raised bumps on my forehead. i reduced the dosage to 1 pill a day and everything is back to normal. one thing i was not expecting was the increased libido.
