This is a great product to get both types of L-carnitine recommended by Dr. Sinatra for heart health (and brain health). It’s pricy, but worth it.

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.

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.

right on time, very good.

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

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.
