BUY FROM THESE SELLERS :
I bought creatine monohydrate(jar) from the Nakpro website and the product didn't have the authentication sticker on it. I wrote an email to Nakpro and called them several times and I am pretty sure there's only one female doing all the work at Nakpro. Nakpro has the worst after sales and they didn't take my product back they said it's fine to consume.
Awesome product
