i agree with bumpo. test usually kiks in for me on like week 4-5 therefore, runnning it for only 6 weeks is not logically FOR ME!although every1 reacts to AS differently therefore, shoot for like 10 weeks and if u notice u arent going anywhere after 8weeks then stop. i know some get most of there growth at the end of a cycle , so its trial and eror my friend let us know how u make out, Goodluck...
