Narcotica Nitro Glycerine is a stimulant-free pre-workout pump booster built for maximum blood-flow support and an intense muscle feel—without caffeine. Each serving combines a high-dose pump matrix of 6,000 mg L-citrulline malate, 4,000 mg L-arginine HCl, and 3,000 mg glycerol, rounded off with a “metabolism boost” blend featuring bilberry extract, inulin, and Bifidobacterium bifidum. Simply mix 15 g (3 scoops) in about 500 ml water and drink it 30 minutes before training for a refreshing, easy-to-use pump drink that fits perfectly into hard training phases—especially when you want performance support without stimulants.
