Inspired Nutraceuticals FSU Serum is a high-yield, stimulant-free liquid pump elixir designed to force extreme hyperhydration, skin-stretching vascularity, and volumetric muscle fullness. Created for dedicated lifters, athletes, and evening gym-goers across Australia chasing that deep, unyielding pump, this ultra-concentrated liquid bypasses the clumping and chalkiness of traditional powdered pump supplements to saturate muscle tissue with a massive 20 grammes of active glycerol.

Key Benefits & Features

• Massive 20g Active Liquid Glycerol: Delivers a full clinical dose of liquid glycerol per maximum serving to pull fluids directly into skeletal muscle tissue.

• Eliminates Chalky Silica Fillers: Pure liquid format avoids the unabsorbable anti-caking agents found in powdered glycerol, ensuring rapid digestion with zero gastrointestinal distress.

• Intense Intracellular Hyperhydration: Floods muscle cells with water and critical nutrients to increase cellular volume and delay exercise-induced fatigue.

• 100% Stimulant & Caffeine-Free: Perfect for late-night training sessions where you want sleeve-splitting pumps without keeping you awake.

• Versatile Liquid Delivery: Take it straight off the spoon as a potent shot or mix it seamlessly into your favourite intra-workout or pre-workout beverage.

How It Works

Traditional pump powders heavily rely on powdered glycerol monostearate or bonded glycerol, which often consist of up to 35% silica or stearates just to stop the powder from solidifying into a rock. As a result, standard powders rarely deliver an effective clinical dose and frequently cause clumping in your shaker and bloating in your stomach.

FSU Serum bypasses this limitation by delivering 20 grammes of pure, fully dissolved liquid glycerol. Once ingested, glycerol functions as a powerful biological osmolyte, pulling fluid out of the bloodstream and surrounding tissues and forcing it straight into working muscle cells. This process—known as intracellular hyperhydration—vastly expands muscle cell volume, prolongs cellular hydration during intense exertion, and produces a dense, full, and long-lasting muscular pump from the first set to the last.

Recommended Use

Shake the bottle vigorously before every serving. Consume 1 serving (1 tablespoon / 15ml) for moderate pump support, or 2 servings (2 tablespoons / 30ml / approximately 1 cap) for maximum hyperhydration, taken 20 to 30 minutes prior to training. FSU Serum can be consumed directly as a liquid shot or mixed into 300–600ml of cold water, juice, or your preferred pre-workout. Drink plenty of water alongside each serving to maximise muscle cell volumisation. Do not exceed 2 tablespoons in a 24-hour period.
