Yep, bw(bloodwork) sorry. I have seen those studies, I'm not skeptical about it, I was just wondering if anyone had gotten any done with the transdermal from mr.supps. I ordered mine and will be gettin bloodwork done after a few week of being on it. Was hoping I had someone to compare to - you can read studies/profiles of drugs, but (to me atleast) I like it when I get info from real time bodybuilders. Seems to just be more downtoearth and relative to our goals.
