GREAT flavor, MACROS, and mixes smoothly. Nothing bad to say about this product AT ALL. HIGHLY RECOMMEND THIS!!!

Verified Buyer

My favorite flavor protein. Not to sweet, but just right taste IMO. For comparison not as sweet as Controlled Labs Orange Kream. Would recommend

  • 9 Fudge Brownie
  • 10 Rocky Road - Exclusive!

One of my favorites on the market (if not my favorite). Mixes great, no clumps, tastes amazing. I've had two flavors of Dymatize ISO 100. Both flavors were great but Rocky Road is one of my all-time favorites. Plus it mixes really well with just water and tastes good with it. I usually took it once after my workout 4 times a week and then before bed everynight. I put on 4 lbs in 4 weeks and I'd say a good chunk of that was due to eating healthy and this protein. Big fan.

Have to always give props when they are due and Dymatize never dissapoints, this is one of the purest proteins on the market and well worth the money. Every flavor I have tried has been top notch, easily mixes with water or milk and tastes great every time. If you want a great tasting, super pure protein Dymatize is the best!

  • 10 Birthday Cake

One of the best tasting whey isolates I have ever used. Mixes instantly in my shaker cup and doesn't leave me feeling bloated or gassy at all. Great isolate all around.
