You buy the cheapest creatine you can find to save money.
Love the thriftiness, but you’re actually doing a disservice to yourself. It’ll have a ton of impurities and might not even hit label claim.
As for price, check out Amazon. Even before the subscribe and save discount, Purest Creatine is $1.20 per oz. The cheapest, best seller is $1.22 per oz.
There is no reason NOT to buy Purest Creatine.
