100% Whey Protein Isolate

Why Use Yeti's Muscle Powder?

22 g of ultra-pure, cold-filtered whey isolate per scoop. Fast-absorbing, lactose-minimized, and loaded with the complete amino acid profile your muscles need — especially leucine, the master switch for muscle protein synthesis.

Trigger Muscle Protein Synthesis

Whey isolate delivers ~2.2 g of leucine per scoop — clearing the 2 g leucine threshold required to maximally stimulate muscle protein synthesis. Nothing else builds muscle without this switch flipped.

Fast-Absorbing Recovery

Isolate is processed to digest 2–3× faster than whey concentrate — amino acids hit your bloodstream within 30 minutes, accelerating post-workout repair when your muscles are most receptive.

Build Lean Muscle

Clinical doses of 22-25 g whey isolate post-training produce greater lean-mass gains than equivalent calories from carbs or slower proteins — a well-replicated finding across 20+ years of studies.

Support Satiety & Immunity

Protein has the highest thermic effect of any macro and keeps you full longer. Whey is also rich in immunoglobulins and lactoferrin, which support immune resilience during heavy training blocks.

What's Inside

Pure Protein. Nothing Else.

Cold-filtered, instantized whey protein isolate with a natural French vanilla flavor system. No artificial colors, no gums, no fillers.

Whey Protein Isolate (French Vanilla)

Whey isolate is produced by cross-flow microfiltration, which strips away nearly all lactose, fat, and cholesterol while preserving bioactive fractions like alpha-lactalbumin and immunoglobulins. It delivers a complete amino acid profile with the highest biological value (BV) of any protein source — meaning more of what you drink actually ends up rebuilding muscle.

Directions

How To Use Yeti's Muscle Powder

01

Mix One Scoop

Add 1 scoop to 8–10 oz of cold water or milk. Shake for 15 seconds in a shaker bottle or blend for a thicker smoothie. Instantized for no clumping, no grit.

02

Post-Workout Window

Best results come from drinking within 30–60 minutes after training — the period when your muscles are most primed to absorb amino acids and rebuild.

03

Anytime You Need Protein

Use as a breakfast, snack, or between-meal boost to hit your daily protein target. Stirs smoothly into oatmeal, yogurt, and pancake batter.

04

Hit Your Daily Protein

For muscle growth, target 0.7–1 g of protein per lb of bodyweight daily. Yeti's is a fast, reliable way to bridge any gap in your whole-food intake.
