I just bought this supplement from my local nutrition store called "K-Blast" made by next level nutrition. ive never heard of it before but i have a huge ripped friend who said he took something called K-2 so i asked the guy at the store about k-2. he said he thinks that K-Blast is what my friend was talking about. he told me all about it and that its Nitric Oxide with Kre-Alkaline creatine arginine caffeine and a couple other things. he said its one of the only products hes seen and used thata ctually does what it says. there was only 1 bottle left and i asked him if he had anymore. he showed me the epmty shelf it was sitting on, and the empty shelf above it and said they were both full of the K-Blast about 2 weeks ago. i bought the stuff and am gonna start tomorrow. i cant seem to find any info about it on the web, not even next level nutrition so im wondering if anyone has heard of this or used it.
