Have you ever tested your BG Levels with that product?
I have on multiple occasions and found it do absolutely nothing for baselining my BG, but that may just be me.
Glycoshield (HPS)
Slintensity V2 (Evomuse)
Predator (Chaos & Pain)
Those are my top 3 favorite GDA’s that have actually worked well. I have found these 3 personally (for me) aid larger meals, cheat meals, and when tested on 25/50/75/100g of carbs. Everyone may respond different, but if you don’t really test a GDA with a blood glucose monitor it may be very hard to know how well one truly works.
