3rd
1193-2386
4th
2386, which is a HELL of a lot.
But I seriously don't agree with these guys who say just dive in near third, especially when we're talking about such high doses. This is not about how tough you are, and we're not talking about alcohol here. You have to take the whole dose at once to get the proper effect, so there's no testing the waters and having a little more later, and there's no stopping when you go to far. You just have to ride it out. So be careful. This can get BAD when you do to much. Start off with like 100 mg, to test that your not enzyme deficient (you shouldn't feel anything, but it's an important test). Then wait a day or two and go for a 354 mg bottle, maybe less. If that's OK, Then add some next time. But never more than double it. It might take you a while to get up there, but the lower plateaus are fun in and of themselves, and it's much better to play it safe.
