Hi-Tech Pharmaceuticals AMP3D is the brand's flagship extreme high-stimulant pre-workout — the successor to Krank3d and Jack'd Up, built around two innovations that separate it from every other pre-workout in the Hi-Tech lineup: Citrulline Silicate (Nitro-Rx®), Hi-Tech's proprietary NO compound combining citrulline with silicon for sustained arginine elevation and superior NO production, and BEC (S-(2-boronethyl)-L-cysteine HCl), a novel arginase inhibitor that prevents arginase from breaking down arginine before it can be converted to nitric oxide. The result is a formula that saturates the arginine-eNOS-NO pathway from two angles simultaneously — increasing arginine production while blocking its degradation — for maximum muscular vasodilation. On top of the pump architecture: 4,000mg L-Citrulline, Agmatine Silicate, L-Arginine HCl, Beta-Alanine, Glycerol, Taurine, and the 590mg Neurogenix Energizer Blend — Caffeine Anhydrous (~300mg), DMHA (2-Aminoisoheptane), Theobromine, Phenylethylamine HCl, and Yohimbine Extract. 25 servings per container. Start with half a scoop on an empty stomach to assess tolerance. Do not exceed 2 scoops in 24 hours. Not for tested athletes. California Prop 65 Warning applies.†
