GAT Sport Nitraflex Glycerol, 473g (32 Serves)

GAT Sport Nitraflex Glycerol, 473g (32 Serves) is a stimulant-free pre-workout support powder built for lifters who already have their stimulant dialed in and want more out of their pump and hydration. As a stand-alone product in the Pre-Workout category from GAT Sport, it delivers 20 g of glycerol per serve alongside beta-alanine and betaine, mixed as 2 tablespoons (30 mL) into water. With 32 servings in the tub, it suits anyone chasing fuller muscle bellies and steadier output through a session, not a caffeine kick.

How GAT Sport Pre-Workout works

Glycerol is an osmotically active compound. Once absorbed, it draws extra water into cells and the spaces around them, a process often called hyperhydration. That expanded fluid volume is what lifters feel as fuller, tighter muscles mid-session, and it can also support how your body manages temperature under load. GAT Sport Nitraflex Glycerol supplies 20 g of glycerol per serving to trigger that effect.

Beta-alanine works differently. It is a precursor to carnosine, a compound stored in muscle that helps buffer the hydrogen ions produced during high-rep, high-intensity sets, so more carnosine on board can mean tolerating fatigue a little longer. Betaine acts as an osmolyte inside cells, helping them hold water under metabolic stress. GAT Sport Nitraflex Glycerol combines both at 2 g of beta-alanine and 2.5 g of betaine per serve.

Why choose GAT Sport Nitraflex Glycerol, 473g (32 Serves)

At $58.95 for 32 servings, this tub works out to a modest per-serve cost for a stimulant-free pump and hydration product, so timing it around training stays flexible. Each serving contributes 90 calories and 20 g of total carbohydrate, worth factoring in if you track macros. Ninety milligrams of vitamin C and 50 mg of sodium per serve round out the hydration profile alongside the glycerol and betaine.

• Mixes as 2 tablespoons (30 mL) into water for an easy shaker addition
• 90 calories and 20 g of carbohydrate per serve, worth noting if you count daily totals
• Built on purified water, citric acid, cultured dextrose and pink Himalayan salt, with no stimulant listed

Getting the most from it

Most people mix GAT Sport Nitraflex Glycerol before training, sipping it as they warm up so the glycerol has time to shift fluid toward working muscle. With no stimulant on board, it layers cleanly under your usual pre-workout without adding caffeine, and some lifters use it alone on rest days for the hydration support.

If you already run a creatine routine or reach for electrolytes around long sessions, glycerol slots in as another piece of the same fluid picture rather than competing with either. Keep water intake generous, since glycerol needs the extra fluid to work, and treat the 32 servings as roughly a month of consistent use.
