Sirtris is working on a formula and drug using Resveratrol and what it has provided in research. They are actually in testing using a resveratrol formulation of 2500mg and 5000mg on human subjects.

You can see this on their IPO screenshots here

Sirtris doesn't sell any solution at this time, they really are looking for a drug that can be patented instead of a natural source of resveratrol.

RevGenetics is a company that sells 500mg Resveratrol capsules that comes from natural sources.

I hope Sitris comes out with something by 2009, but for now we have some natural sources.
