PEScience: Brand Review

PEScience Select Protein has a dedicated following built on a specific use case: protein powder that works as a baking ingredient. The casein component in the whey + casein blend holds moisture when heated, giving better texture in protein cookies, pancakes, and muffins than pure whey. Combined with dessert-accurate flavors (Cake Pop, Frosted Sugar Cookie, Snickerdoodle) — where the name actually matches the taste — it fills a niche few protein brands have bothered to compete in seriously.

Quick summary

Select Protein is the baking-protein benchmark — whey + casein blend, dessert-accurate flavors, low carb, gluten free, third-party tested. $49.99 for 27 servings. The flavor range is the strongest in the category.

  • Whey concentrate + milk protein concentrate (casein) blend — better baking texture than pure whey
  • 12 dessert-forward flavors including Cake Pop, Frosted Sugar Cookie, Snickerdoodle
  • Low carb, gluten free, third-party tested
  • $49.99 for 27 servings (≈$1.85/serving) from pescience.com — mid-premium price point
  • Also available: Select Vegan ($44.99), ISOLATE ($49.99), protein pancake mixes

PEScience Select Protein

24g protein, whey + casein blend, the baking-protein standard

The Data

The Pro Tip

For baking, use Select Protein to replace roughly one-third of the flour in any cookie, muffin, or pancake recipe and reduce the sugar slightly (the flavoring is already sweet). Snickerdoodle and Peanut Butter Cookie are the most versatile baking flavors because they add distinct character without overpowering other ingredients. Gourmet Vanilla is the all-purpose choice if you want flavor neutrality.

The Honest Critique

27 servings per tub is a small container. At $49.99 for 27 servings ($1.85/serving), the entry-level tub runs out fast for daily users. The 55-serving size is better value but a bigger upfront commitment before you know if you like it. By comparison, Quest Multi-Purpose Mix delivers similar baking performance at $1.08/serving (3 lb tub, from questnutrition.com May 2026) — the PEScience premium is for the superior flavor range, not meaningfully better protein performance.

PEScience Select Vegan Protein

24g plant protein, 5 flavors

The Data

The Pro Tip

The Vegan Select is PEScience’s plant-based option for buyers who want the brand’s flavor-forward approach without dairy. The price ($44.99) is competitive for a flavored, certified plant protein.

The Honest Critique

5 flavors is a narrow range. The appeal of PEScience is the dessert flavor variety — the vegan line doesn’t fully deliver that. For plant-based protein with broader credential coverage (NSF Certified for Sport, USDA Organic), Garden of Life SPORT is the stronger choice.

PEScience ISOLATE

27g whey isolate — the higher-protein, cleaner-macro option

The Data

The Pro Tip

If you want PEScience specifically for the flavors and baking use, Select Protein is the better product — the casein blend is what gives it baking performance. ISOLATE is for buyers who want the brand and need an isolate formula.

The Honest Critique

Two flavors defeats the point of choosing PEScience. The brand’s key differentiator is its flavor range. At the same price as Select Protein with dramatically fewer flavor options, ISOLATE only makes sense for buyers who specifically need the isolate macros and are already PEScience loyalists.

Buyer’s Guide: Is PEScience Right for You?

1. If you bake with protein powder, Select Protein is one of the top two options. The casein blend handles heat better than pure whey, and the flavor names match the taste — Frosted Sugar Cookie tastes like frosted sugar cookie. Quest Multi-Purpose Mix is the main competitor — similar baking performance, lower price, fewer flavor options.

2. For shake-only use, the value case weakens. At $1.85/serving, Select Protein is more expensive than Optimum Nutrition Gold Standard ($1.52/serving at sale pricing) and Myprotein Impact Whey (under $1.30 at sale). The premium is for the flavor experience — if you’re blending with milk and not particularly fussy about flavor, there are better-value options.

3. The flavor names are accurate. “Frosted Sugar Cookie” tastes like frosted sugar cookie. This is rarer than it sounds in protein powder — most brands name flavors aspirationally and deliver a generic sweet taste. PEScience’s flavor accuracy is the reason the brand has the loyal following it does.
