Someone else will say it, but the type of GDA will vary person to person. Some people will do great with Berberine, or even just something like a Cinnamon Bark Extract with some chromium. I personally Like using GDA’s on my Higher carb days. Ill like to use some pre-made products, and some of just the single ingredients depending on the meal. My current favorite product is Matador from project A.D. But I have been curious about trying out Adapt from outbreak nutrition.
