I am told that GNC products are better quality then other supplements that I can find online (specifically, C4, whey protein, whey protein isolate and weight gainer). Is this true or am I just wasting my money?
You should never shop at a GNC store. They sell junk supplements you don't need. 90% of their products are scams. Over $20 billion of worthless supplements are sold in the US every year. Don't be one of the suckers.
