To go a little father, based on the math above and the descending order of dose used in prop blends, we can calculate the maximum dose of each of the first four ingredients (note that the maximum dose for all ingredients can not be achieved at once, as if the dose of one ingredient is increased, other(s) have to be decreased):
ALCAR: Since we have a maximum of 2384mg between the 4 ingredients, and ALCAR is first, it is the highest dosed (or equally highest dosed) ingredient. Since there seems to be 250mg Vitamin C, and three other ingredients (besides ALCAR) come before it, they should each have at least 250mg each, or at least 750mg between them. That leaves 1634mg for ALCAR at the maximum.
Taurine: Using similar logic, except assuming that you need to have an equal (or greater), dose of ALCAR as taurine, and at leas 250mg each of choline and tyrosine, you're left with 1884mg between ALCAR and taurine, of which no more than half, or 942mg, can be taurine.
Choline Bitartrate: 2384mg, minus 250mg minimum for tyrosine leaves a maximum of 2134mg for ALCAR, taurine, and choline, of which no more than 1/3, or ~711mg can be choline bitartrate.
Tyrosine: 2384mg, of which no more than 1/4, or 596mg, can be tyrosine.
I think the math is accurate, but it's late.
