A dessert-like protein for people who want a shake that tastes like a treat at any time of day. The mixed protein blend is slower and richer than a pure whey, which is not for everyone after training.

Overview
A pantry shelf or the gym bag is home for this BSN tub, a vanilla ice cream protein powder meant for any time of day. Its blend mixes whey concentrate and isolate with casein, milk protein isolate and egg albumin.
Taste is the headline, and the multi-source blend makes it work as a snack or between-meal shake as well as after a workout. Casein and the richer profile mean it is less lean than an isolate-only powder.
Who it's for
Suited to those who struggle to drink plain-tasting protein and want something closer to a milkshake. Lifters chasing the leanest possible macros should choose an isolate.
Pros and cons
- Dessert-like vanilla flavor
- Blend of fast and slow proteins
- Large tub with many servings
- Works at any time of day
- Contains milk, soy and egg
- Not a pure isolate
- Large tub needs storage space
Performance notes
Mixing fast whey with slow casein and egg protein spreads amino acid release over hours, which suits snacks and gaps between meals. That slower digestion also gives the shake a thicker, more filling feel.
