Description
FSU: Nitrum is the next evolution in non-stim pre-workout liquids, engineered by Inspired Nutraceuticals and V1 Nutra to flood your muscles with peak hydration, relentless endurance, and skin-splitting pumpsall without caffeine. When it comes to pumps, size matters: a massive 20,000mg dose of GlycoClear Glycerol supercharges muscle hydration for fuller, harder pumps and endless endurance, while 3,000mg of Citrulline Nitrate (as NO3-T) unlocks nitric oxide production for insane vascularity and circulation. Rounding out the formula, 1,000mg of NitroCarn (Glycine Propionyl-L-Carnitine) fuels muscle function, recovery, oxygen utilization, and even greater nitric oxide production. 100% stimulant-freeno jitters, no crashpure pump liquid that stacks with anything. Crush every set, dominate every rep, and feel the power in every flex. Take 1 full serving 15-30 minutes before your workout with a full glass of water. Available in Passion Play, Kiwiberry Haze, Gummy Glacier, and ‘Nana RaspbARES.

20g GlycoClear GlycerolSolving the “Sand” Problem
Most glycerol powders on the market are standardized to only around 65% actual glycerola fact the brand has publicly criticized, noting that consuming a leading glycerol powder means consuming close to the same amount of inert filler alongside it, since that concentration is only truly stable as a powder at that dilution. FSU: Nitrum sidesteps this entirely by delivering glycerol in true liquid form via GlycoCleara full 20,000mg (20g) dose, among the highest glycerol doses available in the category. Glycerol is a potent osmolyte that draws water into and around muscle cells, producing cellular hyperhydrationincreased muscle volume, fuller pumps, and delayed dehydration during training, distinct from the vascular pump that nitric oxide-driving ingredients produce.
3g Citrulline Nitrate (NO3-T)Two Pathways to Nitric Oxide in One Compound
Citrulline Nitrate combines Citrulline’s arginine-conversion pathway with a nitrate ion bonded directly to the moleculemeaning this single ingredient feeds nitric oxide production through two distinct routes simultaneously. Citrulline converts to Arginine in the kidney, feeding the eNOS (endothelial nitric oxide synthase) pathway; the bonded nitrate additionally converts to nitric oxide through a separate, non-enzymatic nitrate-nitrite-NO pathway. This dual-pathway compound is the update from FSU: Nitrum’s predecessor, FSU Serum, which used Arginine Nitrate insteadInspired and V1 Nutra specifically upgraded to Citrulline Nitrate at 50% more total NO3-T nitrate content for a more potent vascularity and circulation effect.
NitroCarn (GPLC)1gThe Third Mechanism
NitroCarn is Glycine Propionyl-L-Carnitine, a specialized carnitine ester distinct from standard L-Carnitine or Acetyl-L-Carnitine. GPLC has documented research on enhancing nitric oxide production independently of the arginine/citrulline pathway, while also supporting mitochondrial fatty acid transport and oxygen utilization during exercise. Including NitroCarn alongside Citrulline Nitrate gives FSU: Nitrum a third distinct nitric oxide-supporting mechanism, on top of its established recovery and muscle function benefits from the carnitine backbone itself.
FSU: Nitrum vs. FSU SerumThe Upgrade
FSU: Nitrum is the more potent evolution of Inspired’s original stimulant-free bulk liquid pre-workout, FSU Serum. The brands carried over the signature 20g dose of GlycoClear glycerol unchanged, but upgraded the nitrate componentswapping Arginine Nitrate for Citrulline Nitrate at 50% more NO3-T nitrate contentand added NitroCarn as an entirely new third ingredient not present in the original Serum formula. If you’re a fan of FSU Serum and have had great results, FSU: Nitrum takes that same experience up a notch.
Frequently Asked Questions
-
Does FSU: Nitrum contain caffeine or stimulants?Nothis formula is 100% stimulant-free. Its effects come entirely from GlycoClear Glycerol, Citrulline Nitrate, and NitroCarn rather than caffeine, yohimbine, or any other CNS stimulant.
-
Can FSU: Nitrum be stacked with a stimulant pre-workout?Yesthis is one of its primary intended use cases. Since it’s completely stimulant-free, it stacks with any caffeinated pre-workout or standalone stimulant product without adding to total caffeine intake, layering additional pump and hydration support on top.
-
How is FSU: Nitrum different from FSU Serum?Both share the same 20g GlycoClear Glycerol dose. Nitrum upgrades the nitrate component from Arginine Nitrate to Citrulline Nitrate (50% more total NO3-T nitrate) and adds NitroCarn (GPLC) as a new third active ingredient not present in Serum.
-
Is FSU: Nitrum appropriate for tested athletes?Based on the disclosed formulaGlycoClear Glycerol, Citrulline Nitrate, and NitroCarn (GPLC)FSU: Nitrum does not appear to contain compounds prohibited by WADA or NCAA. Tested athletes should review the complete label and verify with their governing body as standard practice.
How to Take FSU: Nitrum
Take 1 full serving (2 tablespoons) 15-30 minutes before your workout with a full glass of water. Half-servings can be used for a lighter pump effect. Not intended for use by persons under 18.
