Dual nitric oxide pathway: Delivers both L-arginine and dietary nitrate for enhanced vasodilation and sustained pump
Pure L-citrulline 6,000–6,500 mg: Increases arginine availability for improved muscle hydration and pump
Arginine nitrate (NO3-T) 2,000–2,500 mg: Activates two independent nitric oxide pathways for maximum performance
Hydromax glycerol 65%: Provides intramuscular hyperhydration for fuller, harder pumps
Amentomax plant-based extract: Supports blood flow and thermogenic support for endurance

tastes great.

A bit gritty but good flavours
I got these on sale since they were the final batch of both flavours, so I wasn’t expecting them to be perfect. They don’t fully dissolve the way the newer ones do, but flavours are still good and the price was great.
