What is L-Arginine HCL?
This amino acid produces nitric oxide and can help promote the “pump” you feel when lifting weights.
L-Arginine HCL vs L-Arginine vs AAKG (Arginine alpha-ketoglutarate)
The HCL, or salt, form of L-arginine is arguably better than L-arginine as this format enhances absorption.
The claims behind AAKG is that it is better absorbed than other forms of arginine, but this has yet to be confirmed in studies.
Take 1500mg to 3000mg of L-Arginine HCL once daily before workouts.
