Surge Caffeine-Free Pre-Workout

Surge® Workout Fuel pumps critical nutrients into muscle that stimulate protein synthesis, reduce catabolism, buffer lactate, delay fatigue, and provide sustained energy for any intense or high-volume workout or competition. It’s an elite supplement made for elite athletes and anyone who trains like them. So if you’re serious about training and want to double the results of your hard work, then this formerly “secret supplement” is available to you.*


  • Stimulates advanced muscle protein synthesis*
  • Potentiates critical nutrient transport into muscle*
  • Enhances electrolytes and water balance in hard-working muscle*
  • Combats muscle oxidation from intense exercise*
  • Optimizes intramuscular pH for maximum endurance and increased performance*

For years Biotest has been producing small batches of custom formulas for world-class athletes from various sports and Hollywood actors who need to get into phenomenal shape as quickly as possible for movie roles.

These"secret" supplements are, without question, the most effective legal substances ever made. They’re shockingly potent, costly, and make all the difference in the world in achieving the most significant gains as fast as humanly possible.

Surge® Workout Fuel is one of the secret supplements we’ve made available to the public. To guarantee the most significant gains from training, fully fuel, protect, and reload muscle with Surge® Workout Fuel immediately before, during, and after training.

“This is the simplest, most-effective nutritional strategy in existence to improve body composition and athletic performance. Elite-level workout nutrition, like Surge® Workout Fuel, can double results in body composition during training. If you train intensely, then Surge® Workout Fuel is an absolute requirement. On the other hand, if you’re not into hard training, Workout Fuel is overkill for those not serious about training.”

Jeffrey Stout PhD

“Anyone can benefit – the strength, bodybuilding, or endurance athlete. This formula is designed to stimulate protein synthesis and reduce catabolism, delay fatigue, and provide sustained energy for any intense or high-volume workout or competition.”

Christian Thibaudeau

“The more volume of physical activity you do (not just weightlifting), the more you’ll benefit from Surge® Workout Fuel. The harder you train, the more you need it. If you do nothing but talk to the treadmill bunnies between non-intensive sets, then Surge® Workout Fuel isn’t for you. Save it for those who earn it!”



Beta-alanine is a natural amino acid that buffers the burning fatigue from high-intensity exercise and significantly increases the amount of work you can do. Beta-alanine also reduces mental stress.* LEARN MORE

Betaine Anhydrous

Betaine anhydrous increases muscle power, endurance, workout capacity, and muscle mass. It also increases leanness, improves overall body composition, and helps liver function and cell reproduction.* LEARN MORE

Citrulline Malate

Citrulline malate buffers lactic acid and reduces ammonia build-up, which increases athletic performance and endurance.* LEARN MORE


Electrolytes, consisting of the minerals sodium, potassium, magnesium, and calcium, accelerate rehydration, preventing muscle cramps, poor exercise performance, and premature fatigue.* LEARN MORE

Highly Branched Cyclic Dextrin

Highly branched cyclic dextrin uniquely provides high-performance energy without spiking insulin.* It increases work capacity, decreases stress hormones, increases muscle pumps, and promotes advanced active rehydration.* LEARN MORE


L-Leucine is the essential amino acid most responsible for muscle protein synthesis. Consuming ample L-leucine during workouts stimulates and fuels optimal muscle gains. It also combats muscle oxidation (burning) from intense exercise.* LEARN MORE

Malic Acid

Malic acid fuels cellular energy, increasing peak power and total work capacity. It also can boost growth hormone and improve body composition.* LEARN MORE
