Fantastic ! You have to take 8 caps a day but ... the effect on sexuality is here after just one week. Be patient anyway because each reaction is individual. The mix of ingredients is unique. The price is good for such a quality product. Thanks iherb. Love.

Gets every spot as a male it really gives my testicles a well earned boost.

good product and worthy and I'm happy with it

this is avery cheap and very good product , everybody must use it

. this is the only supplement I could find that has the propionyl form of carnitine; it comes with alpha lipoic acid, and I add a little co-q10.

Life Enhancement, I have long admired them for the quality, useful products.

Delivered on time. Can’t wait to try it.

I tried this product (also called Magnum Force on some sites) & saw no results the 1st month. But after calling Life Enhancement, I was told effects won't begin until 3 months. Well, I'm half-way through my 3rd bottle & WOW, I get an erection every morning like I was in high school. (And I'm someone who would get about 1-2 of those a YEAR before). So, while it is a very expensive item yo use for 2-3 months with 0 effect, it was worth the wait.

I've been using Propel for about 6 months and it's the only thing that has helped my problem with frequent urination. I haven't found any affect on erections but that's a lesser consideration for me.

My wife purchased this because she heard it might help with Parkinson's Disease. At first she wasn't sure there was a difference, but over time she noticed a major change for the better in the shaking. She now takes it regularly.
