they took a while to kick in with me felt effects after an hour but didnt see shit till about 3 hours later. And i didnt have baby wood i had morning glory and took 150 of them...so i cant really tell you the dose....My advise would be take 4 wait an hour see how its goin then take more ezactly like you said...but dont blame me if you dont trip for ages then take all of them........ then get naked
