Extremely effective but with extremely mixed results

Posted by iHerb Customer on February 19 2012 | Verified Purchase

First off, never take more than one in one go. Second, yes, it helped with my desire but not necessarily physical performance. Very importantly, it kicks in about 3 hours later and do not take it along with stimulants, eg. coffee, tyrosine, etc...because it can cause serious rapid heart beat to the point of real danger, especially if you already have hypertension. God bless.

Thanks for your feedback!

This product turned out to be of very high quality. Compared to the same substance that I've gotten in the past, this was of superior quality and it's effects were much longer lasting than I'd expected. It's stimulating properties may find you lying in bed wondering why you can't get to sleep.... use with appropriate timing.

Thanks for your feedback!

Amazing stuff, but be CAREFUL...

Began taking this for ED. I have read elsewhere that Natrol has reformulated this at some point in the last two or three years, and the reformulation made it much more powerful. I took 1 capsule and after about an hour it was very obviously working for me. In fact, it made a huge difference, if you catch my drift... However, the after-affects were significant. Very quickly I broke out into cold sweats. I was shivering and yet sweating quite a bit with a pounding irregular heartbeat. I also was not able to sleep that night at all. I am told that taken daily these side affects become less, but it's hard to imagine taking this daily. Next time I only took half a capsule. Still did the job for me, but side affects were still too severe and I was still up all night. I now divide each capsule into 5 even doses. It still works for me at that dose, although not as well, but still well enough. And the side affects are tolerated. One bottle will last me awhile. The benefit is worth the unpleasant after-affects.

Thanks for your feedback!

Natrol, Yohimbe
