Review on Introducing Ultra Clean Stim Free Pump Pre Workout + Nitric Oxide Booster (Fruit Punch) - Harness the Power of Beetroot, 7G Arginine Citrulline Malate, Betaine, Beta A, ACV+ - Experience a Sugar/Caffeine Free Natural Non Stim Preworkout for Both Men and Women by James Thelin

I have now purchased this supplement and have recently (2 weeks) had severe chest pain. I didn't think it was because of this supplement but it is high quality. I did a little research and found a scary article about ARGININE, even though it was used at a 9 gram dose, all 6 patients died during this 6 month study. Each scoop contains 2 grams. For someone like me, this could be the cause of my severe chest pain for two weeks within three months of use. Usually, aspirin or cayenne pepper in water (vaso dialotor) helps chest pain, but nothing helps. I have discontinued this product and hope this helps. I think making changes to the product just by reducing the amount of arginine would be safer. I've been scared for the last two weeks and this morning I went to the hospital. I know every product works differently but please be careful with the amount of arginine and chest pain you may experience. Kind regards!
