"This supplement has helped me so much, I was on glp1's to lose some weight and manage blood sugar/cholesterol. However, I felt like I was losing all my muscle, I started taking this product and I have maintained my weight, my blood sugars have gone up a little but I think this can be improved with more exercise. So happy with this!"
