Ingredients Guide

The most-researched performance supplement in sports science. It helps replenish ATP — the energy your muscles use in short, hard efforts — which over time supports more quality reps and training volume. Creapure® is the German-made, 99.9%-pure reference standard. Take it daily, including rest days; loading is optional and cycling is unnecessary.

Buffers the acid build-up that makes hard sets burn, which supports work capacity in the 60–240 second range. The harmless tingling (paresthesia) some people feel is normal and temporary — not an allergic reaction.

Nitric-oxide precursors that support blood flow to working muscle — the "pump" you feel, and better nutrient delivery during the session.

The most reliably effective stimulant for training: supports alertness, perceived effort, and power output. Sensitive to it, or training at night? Choose a stim-free pre-workout instead — that's exactly why Category5 exists.

A choline source studied for focus and mind-muscle connection during training. Small dose, specific job — and we print the exact amount rather than hiding it in a blend.

Fast-digesting complete protein with all essential amino acids — the raw material for repairing and building muscle. Concentrate carries slightly more carbs, fat and lactose than isolate, and generally tastes better for it.

Filtered further than concentrate: more protein per scoop, less carbohydrate, fat and lactose. The pick when you're counting macros or lactose bothers you.

The three branched-chain amino acids, with leucine as the primary trigger for muscle protein synthesis. Most useful during long sessions or fasted training — if you already hit your daily protein target, whole protein covers these.

The most abundant amino acid in muscle tissue, studied for recovery support during periods of heavy training load.

What you lose in sweat. They support hydration, fluid balance and normal muscle contraction — which matters most in long sessions, hot climates, and two-a-days.

Protease, amylase, lipase and lactase — enzymes that help break down protein, carbs, fat and lactose. This is why our whey tends to sit easier than protein powders that skip them.

Most people get roughly half the fiber they need. Fiber supports digestive regularity, feeds beneficial gut bacteria, and helps you feel full — the unglamorous foundation of feeling good day to day.

A compound involved in transporting fatty acids into the mitochondria to be used for energy. Commonly used alongside training and a sensible diet — not a substitute for either.

A naturally occurring fatty acid found in dairy and beef, taken as a daily supplement for body-composition support. Ours is safflower-derived and vegetarian-friendly.

Hydrolyzed collagen, studied for skin elasticity and joint comfort. Worth knowing honestly: collagen is not a complete protein and won't replace your whey for muscle building.
