fitness USA says that people taking creatine at a cost of about $12($12 is in your case they quoted $120) per month is unnecessary, when they can get the same benefit by eating and exercising properly.

Fitness USA is not a credible source, especially when they say creatine costs 120 dollars. Find another source, then come back.
