teh reason it sez that is cuz the full line from AN includes other stuff ur supposed 2 use the rest of teh time
if ur not gonna use that stuff like Bud Blood and Overdrive u dont havta limit Big Bud to weeks 2 to 4
u can use it from start to flush if u want
powder or liquid dont matter iirc
been long time since i did teh math but iirc it costs the same either way when mixed up and has same concentration etc
