Pros and cons

ISO100 Hydrolyzed Whey Protein Isolate

  • 25 g of protein and about 2.7 g of leucine per 120-calorie scoop, all from whey isolate
  • Informed Choice banned-substance mark on the label
  • Only 2 g of carbohydrate and 1 g of sugar in Gourmet Chocolate
  • Dymatize publishes a full amino acid profile for the flavor
  • buyers frequently praise fast, clump-free mixing
  • About $1.55 per serving for the 5 lb tub, pricier than whey blends
  • Contains soy lecithin and is sweetened with sucralose (plus stevia in the current formula)
  • Some buyers still report bloating despite the isolate base
  • Evidence for a real-world benefit from hydrolysis is thin, so part of the premium is marketing

Whey Protein

  • Distinctive licensed flavors (Lucky Charms, Cinnabon, Cocoa Puffs and more) that creator reviewers consistently rate highly
  • 25 g of protein per scoop, with the isolate, concentrate and hydrolysate breakdown printed on the tub
  • Soy-free (sunflower lecithin) and gluten-free, with added lactase and protease enzymes
  • buyers say it mixes well and works in recipes such as protein ice cream
  • No third-party banned-substance certification found (NSF, Informed Choice)
  • About $2.12 per serving for the 2 lb tub
  • Sweetened with sucralose and uses artificial flavor
  • Texture and digestion feedback is mixed, with some buyers reporting nausea

Our verdicts

ISO100 Hydrolyzed Whey Protein Isolate

ISO100 is one of the most complete whey isolates you can buy: 25 g of protein per scoop with a published amino acid profile, minimal carbs and fat, and banned-substance certification. You pay a premium over whey blends, and the hydrolyzed angle is more marketing than proven performance edge, but for a lean, well-tested isolate that mixes easily it is a safe pick.

Whey Protein

GHOST Whey earns its popularity on flavor: few powders taste this much like the dessert or cereal on the label. The formula underneath is a solid, fully disclosed whey blend, but with no third-party certification and a price above $2 per serving, it is a treat-yourself pick rather than the best value or the safest choice for tested athletes.
