I seein several new preworkout formulas. Does this have any value, or is it was worthless as regular argninie? I have a bunch of samples, but I might just dole them off onto a friend if they have negative properties like arginine.
There are no negative properties, but there's nothing positive either, really.

The above is my own opinion and does not reflect the opinion of PES
I see, maybe I'll dig into those pwo samples then. My SP max is almost out...Originally Posted by mr.cooper69
