For pure N.O. effects, I would agree that L-Cit is much greater than malate but I don't think anyone(well I'm sure some company probably is) is claiming that Malate standalone enhances nitric oxide more so than L-Cit.
Also, an 8g dosage of 2:1 Cit Malate(which results in 4g L-Cit) will produce the same benefit as 4g L-Cit. Malate itself is not useless, and actually has ancillary benefits.
I think you've made a fine product, but I just felt it was a tad disingenuous to make it seem like L-Cit is far superior to Cit Malate, as it depends on the ratio of the Cit Malays.
No arguments with you on why most companies use CitMal in their products and often don't disclose the ratio in their preworkouts. Some have 8g and are likely 7:1
