Anyone Had Garnell Nitric...

…power storm and had an allergic reaction to it?
I purchased this product a couple of weeks back, after trying it for the first time my ears went dark red along with my nose, arms and knees!
Has anybody tried this product and seen great results on it?

I find it gives me a ‘pump’ but am dubious about using it. I’ve never seen any results on creatine but believe this works.
Any thoughts?
