Questions and answers

Which is better for post-workout?
ISO100. It is hydrolyzed, so it digests and absorbs faster, and it delivers 5.5g of BCAAs per serving. Transparent Labs is a solid isolate but not pre-digested.
Which has more protein per scoop?
Transparent Labs, at 28g versus 25g for ISO100. The gap is small but real over several shakes a day.
Which is cleaner on ingredients?
Transparent Labs. It uses no artificial sweeteners, dyes or fillers and sources grass-fed whey. ISO100 uses artificial sweeteners in most flavors.
Which tastes better?
ISO100 has the stronger reputation for flavor, especially Gourmet Vanilla, backed by thousands of ratings. Transparent Labs flavors are liked but polarizing.
Is it worth stepping up to ISO100?
Yes if fast absorption and flavor matter most to you. No if you want the higher protein dose and a clean label, where Transparent Labs wins.
Which is easier on the stomach?
ISO100, because hydrolysis removes more lactose and breaks the protein down further. People sensitive to regular whey often tolerate it better.
