Well, for one thing, they're really popular on other boards. Many people like different things, but I keep seeing Vanadyl Sulfate and Chromium Polynicotinate pop up. I read alittle bit more into it and these are the two ingredients in Slin-Trol which happens to be a popular item to those that like GDA's. 120caps for $11. Definitly affordable.
Everyone seems to have their own dosing protocol and own tolarances but basically its taken with large carb meals. People report enhanced glycogen storage, so better uptake of glucose into the muscles. This leads to more intense training, more intense pumps in the gym and overall slightly less fat gain. Typically, I hear them mentioned for meals pre and post workout or during re-feeds (which is what im doing) while dieting.
Then you have the peeps that are actually so into this stuff, they go out and buy glucose meters. Taking blood samples before, during and after meals to see how their blood sugar changes with GDA's and without. I've seen lots of accounts from lots of people where their blood sugar either barely went up or came back down to normal VERY quickly (compared to their normal spikes and dips w.o GDA help). They also claim to get great pumps from this and frequently overcompensate their glycogen stores.
So, naturally, I'm very curious about all this and wanted to hear some insight from people around here because they don't seem all that popular in these parts (maybe for good reason).
