The Intra-Workout That Builds Muscle While You Train

Most supplements work before or after your workout. SizeOn works during it. Gaspari Nutrition's SizeOn Maximum Performance is the world's most advanced intra-workout formula - engineered to initiate and sustain muscle volumisation, accelerate protein synthesis, replenish energy, and battle fatigue in real time, while you're still training. The result? You finish your session bigger, fuller, and more recovered than when you started.

The SizeOn Advanced Formula - 4 Precision Matrices:

💪 Protein Synthesis Acceleration Matrix

• Whey Protein Hydrolysate (50%+ Di & Tripeptides) - The fastest-absorbing form of whey protein available. Di and tripeptides are absorbed directly through the intestinal wall without further digestion, delivering amino acids to muscles faster than any other protein source
• 5g L-Leucine - A clinical, research-backed dose of the most anabolic amino acid. Leucine directly activates the mTOR pathway to trigger muscle protein synthesis - even mid-workout
• L-Isoleucine & L-Valine - Complete BCAA profile for muscle protection and endurance during training

⚡ Phosphodrive Endurance & Creatine Complex - Triple Creatine Matrix

• Creapure® (Creatine Monohydrate) - The gold standard of creatine. Creapure® is the purest, most tested creatine monohydrate available, manufactured in Germany to pharmaceutical standards
• Creatine MagnaPower® (Magnesium Creatine Chelate) - A patented form of creatine bonded to magnesium for enhanced absorption and superior ATP regeneration
• Disodium Creatine Phosphate - Directly replenishes creatine phosphate stores in muscle for immediate energy availability during high-intensity exercise

🍊 Carbohydrate Energy Matrix

• Cyclic Dextrin - A premium, high-molecular-weight carbohydrate that empties from the stomach rapidly for fast energy delivery without bloating or discomfort
• Trehalose & Dextrose - Fast-acting carbohydrates to replenish glycogen stores and sustain energy throughout your session
• Pterostilbene - A natural insulin secretagogue that works in concert with the carbohydrate matrix to drive nutrients into muscle cells more efficiently, enhancing muscle volumisation and anabolism

💧 Osmodrive Advanced Hydration Complex

• Sustamine® (L-Alanyl-L-Glutamine) - A patented, dipeptide form of glutamine that is absorbed significantly faster than standard glutamine. Supports hydration, endurance, and recovery during prolonged training
• Sodium, Calcium, Potassium & Magnesium Glycerophosphates - A complete electrolyte matrix to replace minerals lost through sweat and maintain optimal muscle function
• L-Taurine - Supports cellular hydration, reduces cramping, and enhances endurance performance
• LOLA (L-Ornithine L-Aspartate) - An ammonia-scavenging amino acid salt that combats training-induced fatigue by clearing toxic ammonia build-up in muscles

What You'll Experience During Your Session:

✓ Immediate Muscle Fullness - Feel your muscles volumise and fill with nutrients from the first sip
✓ Sustained Energy - Cyclic Dextrin + Trehalose keeps energy levels stable throughout your entire workout
✓ Greater Strength & Power - Triple creatine matrix including Creapure® boosts ATP for more weight and more reps
✓ Accelerated Muscle Protein Synthesis - 5g Leucine + Whey Hydrolysate triggers muscle building mid-workout
✓ Reduced Fatigue - LOLA scavenges ammonia while Sustamine® and electrolytes keep you performing at your peak
✓ Superior Hydration - Complete electrolyte matrix replaces what you lose through sweat

Why Intra-Workout Nutrition Matters:

During intense training, your body is simultaneously breaking down muscle tissue and depleting energy stores. Without intra-workout nutrition, this catabolic process goes unchecked for the entire session. SizeOn intervenes in real time:

• Whey Hydrolysate delivers amino acids to muscles within minutes of consumption
• 5g Leucine triggers muscle protein synthesis while you're still training
• Creatine replenishes ATP between sets for sustained power output
• Carbohydrates maintain glycogen levels so you don't hit the wall mid-session
• Electrolytes and Sustamine® prevent dehydration-related performance drops

The result: you finish your workout in a more anabolic state than if you trained without it.

Why Creapure® is the Gold Standard:

Not all creatine is equal. Creapure® is manufactured in Germany to pharmaceutical-grade standards and is the most tested, most trusted form of creatine monohydrate in the world. It's the creatine of choice for elite athletes and is independently verified for purity and potency. SizeOn uses Creapure® as its primary creatine source - alongside two additional creatine forms for a complete triple-action creatine matrix.

Perfect For:

✓ Serious athletes wanting to maximise every training session
✓ Those doing long, intense training sessions (60+ minutes) who need sustained energy
✓ Hard gainers wanting to build muscle size and fullness faster
✓ Anyone wanting to combine protein, creatine, carbs, and electrolytes in one intra-workout drink
✓ Those who want to feel the difference during their workout, not just after
