hey mr spliff- i'm real new to this site, from vegas and have noticed you seem to know a bit about testing clean . i'm not sure how to contact you directly through this site so i'll try this reply method. i'm logged in as alphamunky and posted a thread in the drug testing forum as well as the general forum about certo and exactly why it works and how long my window is . i have a test coming up on the 10th of june. i'd like to get a head start on this and maybe a practice run. the certo i've found comes in gelatin packets (8oz). could you help me by replying to one of those threads or tell me how to properly use this site-thanks alphamunky
