I took weight gainer for a while, it worked but thats all you do really. Gain weight. I had very little tone and basically just got bigger; especially around the mid section
But I did gain some weight, about 40 lbs or so.
But recently I decided to cut that out and go with a clean protein. I'd rather be leaner w/ a little bit of fat than fat with almost no tone.
You could take gainer, but maybe cut down the servings to half the size or something, however if you do that, you're also cutting down your protein intake.
Thats the problem with gainer. If you want the maximum protein, you're also taking in huge amounts of calories which is probably mostly sugar.
Like someone said earlier, if you take gainer, you'll probably be broke, and its true. The GOOD gainers with less sugar cost ALOT of money.
