L-Arginine is one of the most popular bodybuilding amino acids for good reason. Copious amounts of research have shown that it has a potent vasodilation effect, which brings more nutrients to muscle tissue. It’s also been linked to enhanced muscle synthesis, proper immune system function and potential cardiovascular support. Although L-arginine is available in many food sources, its many benefits add to its important use in supplement form. Trust ProSource for the highest quality aminos on the market.
Use as directed with a sensible nutrition and exercise program. Read and follow all product label instructions and warnings thoroughly before use.

It's fantastic and amazing product. Pumped muscles and vascularity. I tried to buy this product to see if they really work! Now I am sure they work. I stick on them and I still use every single day.

Fantastic product. I normally buy the Prosource elite diet support stack. This diet stack is fantastic and these products do not contain caffeine like a lot of diet proucts do and you don't get the shake,s etc. Drink plenty of water each day and there are no cramps with this diet stack that I have experienced with other diet produts I have used over the years. I like to use this with the Extreme Test Stack II Plus. It really works well.
