Question on Insulin Secretagogues / GDAs

I've been doing a lot of reading on insulin and it's effects for bodybuilding, and thinking about trying a secratagogue / GDA the next time I bulk. No way I'd do injections so I'm not too worried about hypoglycemia or some of the other negative side effects. Just wondering if anyone on the board has any experience with them, if they work, or if I'd be just as well off eating the right things at the right times, controlling insulin release naturally.

I'm specifically looking at Insuligen from masupps ( LINK). 777, I know you recommend Mike's mk-677 supp, I've actually used a couple bottles and have had great results, wondering if you know anything about his insulin supp. I know his secratagogue has some extra stuff in it to provide benefits like preventing fat gain that is typically associated with insulin increases, wondering how legit those claims are. It also claims to keep blood glucose at natural levels on the low end (because it's glucose dependent), so you don't have to worry about hypoglycemia.

Thanks in advance.
