I'm using the product now for 6 weeks. Since it's my first BCAA powder, I was especially curious about the water solubility. This is for me, however, absolutely no problem, because I always throw everything in principle in the blender. The powder remains even after several hours well resolved (after 10 hours of work drunk), only a small fraction settles to the bottom, but can be resolved by briefly shaking.
One point I would like to highlight this product: There is no (bad) surprises. The product are added caffeine or similar additives. The BCAA ratio is 2: 1: 1 (Leucine: valine: isoleucine) and glutamine. It is briefly mentioned in the description. You could ev. Make it clearer. It is added as well as Vitamin B beta-carotene for color.
Sweeteners: acesulfame K, sucralose
The taste I can still pull off the product something that I find it tastes good (lemon, 4 out of 5 stars) - you may just do not expect a delicious refreshing drink.
The product is used by me about 3-4 times a week, alternating with amino acids in tablet form (see my reviews). The powder is reappointed, as it serves its purpose, is favorable and no surprises regarding the ingredients offers.
For me 4.5 stars. Is rounded up.
