I found this pre work out supplement

[PrettyPlease?]

Wow 450 mg caffeine! I was under the impression mr hyde had the highest caffeine matrix (415 mg) on the market.

There is a preworkout from Metabolic Nutrition called E.S.P with 500mg

Yes, but that's 500 mg per 10 g of E.S.P.

Ten grams of mr hyde has 559 mg of caffeine.

Ten grams of pep test will have 563 mg of caffeine.

My apologies. Not sure I follow the logic for breaking it down that way as opposed to per serving?

Gram for gram the other two supplements contain more caffeine.

E.S.P has three different serving sizes that are based on mass (3.3 g, 6.6 g, and 10 g).

I think it's a bit silly to say one supplement has more caffeine just because the suggested serving is larger.
