Well truthfully hun, you're not going to find a weight gainer with that low of sugar. Most of them have really high levels of sugar.
I would suggest picking up some whey protein and make your own weight gainer/meal replacement shake.
www.directconnection.com is the place to go.

I agree. I would just mix my own weight gainer shake with milk, whey protein, ground oats, and some healthy fats.

Serious Mass from Optimum Nutrition.
It rocks.

Where can I find it, on what website.

I would say mammoth 2500. Its rad stuff, i stacked about 20 pounds on with it. But you have to eat a lot, then have the shake. then when you feel like your going to throw up, then thats when you know you are starting to gain!
