L-Arginine 300 g – Nitric Oxide & Pump Support for Serious Training
K2 Protein L-Arginine 300 g is a high-purity amino acid supplement designed to naturally increase nitric oxide (NO)levels — improving blood flow, muscle pump, nutrient delivery, and endurance.
Each serving provides 3000 mg of L-Arginine, a proven precursor for NO production that helps athletes train longer, lift harder, and recover more efficiently.
L-Arginine is one of the most essential pre-workout amino acids for pump, strength and vascularity — and this formula is 100 % pure, vegan, unflavoured and filler-free.
