Yeah, I always take Metformin in the morning, along with the resveratrol, because for a number of reasons, but mainly because my body responds better and I've been measuring my body for 12, 13 years. But here's the thing, if I'm going to exercise that day, I will skip the Metformin. And a lot of people who do pay attention to this kind of thing, think that they should stop taking Metformin 'cause they're never going to get muscle, or it's going to affect their ability to build up muscle. But that's not true, what Metformin does to you, it actually just reduces your ability to have stamina because it's inhibiting your body's ability to make energy. And so what happens is when you're on Metformin, you do fewer reps.
