lol arnold jr has to be explained this
ester will be eaten off my enzyme in some time period, it will be something like 7-24 hours, it wont be a set 5 hours or something like this because there is variance, some of the molecule will have the ester stripped quickly and some will take a little longer
now ad to that the half of the actual chemical u want, lets say it's 12 hours
so now it changes to 7-36 hours
the 7 could be 0 if some of the esters are stripped right away, it varies i guess, u get the point
