Should you buy the Dymatize ISO100 Hydrolyzed 100% Whey Protein Isolate (Gourmet Chocolate, 5 lb)?
Dymatize ISO100 Hydrolyzed Whey Protein Isolate is the 100% whey protein isolate (no concentrate) for lactose-sensitive lifters and cutting phases at $89 per 5lb tub. The 25g protein per scoop is pure hydrolyzed whey isolate, the pre-digested hydrolyzed form absorbs faster than standard isolate or concentrate, the 5.5g BCAAs and 2.7g leucine per serving cover muscle protein synthesis thresholds, the under-1g lactose per serving makes it tolerable for most lactose-sensitive users, the 1g sugar and 110 calories fit cutting macros, and the Informed-Choice certification protects against banned substances. The trade is real money over standard whey blends and a thinner, less-dessert-like mouthfeel some users prefer.
