Supplements, as iamyuanwu said, are just bits of food concentrated and processed into powder. They're not pixie-dust in a tub. 2 weeks is too short a period of time to see any visible differences. Strength wise, you might get a little gains, but they will be miniscule. A month or two is more or less bare minimum for one to see significant gains.
