I haven't looked into it much but isn't it quite costly? I only caught a few mentions and the price came up each time. Or does that change once it moves past the early stage like the others did?
I'm about six months in and expect another three to five months to hit my target based on body-fat numbers. After that the idea is to drop to a steady holding level. If sides stay low I don't see much reason to switch things up. Having a couple of backup choices ready is fine, but chasing the newest option doesn't matter once the goal is just staying where you are.
