Protein and creatine. The two most research-backed supplements for building lean muscle — now bundled together and save $10 vs. buying separately.

The Lean Mass Stack pairs PEScience’s flagship protein with Creapure®-certified creatine monohydrate, giving you everything you need to fuel muscle growth, support recovery, and hit your goals without overcomplicating your stack.

What’s included:

  • Select Protein or Select Vegan Protein (27 servings) — premium whey + casein blend (or pea + brown rice for vegan), milk protein isolate as the #1 ingredient, low carb, gluten free, third-party tested. Available in 10+ flavors.
  • TruCreatine+ Powder or TruCreatine Capsules (30 servings) — Creapure® micronized creatine monohydrate, the most trusted creatine source in the world. Your choice of powder or capsules.

Mix and match to build the stack that fits your routine — dairy or vegan protein, powder or capsule creatine. Either way, you’re getting two of the most effective supplements on the market, from the brand that’s been doing this right since day one.

Simple. Proven. Effective.
