What is Arginine?

Arginine Alpha Ketoglutarate (AAKG) is the primary ingredient in most pre-workout, cell volumising supplements. It’s an amino acid compound that’s been shown to help increase muscular ‘pump’ and vascularity as well as the delivery of blood, oxygen and nutrients to the working muscles during exercise.

What is Arginine Alpha Ketoglutarate?

Looking more specifically at the profile of Arginine Alpha-Ketoglutarate (AAKG), it is a conditionally essential amino acid that plays a number of vital roles in human biochemistry. In particular, it has an important role to play in protein synthesis, the process by which the muscles use protein to repair and regrow bigger.


What are The Benefits of Arginine?

The addition of the -Ketoglutarate compound helps improve the delivery of L Arginine in metabolic pathways. In simple terms, this helps the L Arginine to work more effectively within the body which is designed to assist you in achieving superior results.

Can Arginine Help Endurance Sports?

Although Arginine Alpha-Ketoglutarate (AAKG) has been historically used by strength athletes and bodybuilders looking to increase muscle size and nutrient uptake, it’s more recently been used by endurance athletes too. This is because AAKG is known as a vasodilator, which means it widens the blood vessels within the body, and it’s theorised by experts that this vasodilation could allow more oxygen, blood and nutrients to be delivered to the muscles, therefore improve an athlete’s aerobic fitness.

Not too sure
very happy with this product, exceeded my expectation by far, definitely improves muscular pump and vascularity. very good value for money.
Great value for money, always add this to my preworkout :)
I got unflavoured so I could mix with anything I felt like. Use for pump before/during a workout or just general vascular health. Either way, it makes my veins come out.

For free protein on your first order use the code: JB82889.
Get a great pump from this, and i feel my muscles work a lot more efficiently.

Been looking for a good pre-workout with no creatine for a while. Great pump, good mental stimulation. Muscles feel and look visibly fuller
