Depends on who you ask. A single molecule is missing, which makes it sound like it's "real close" but as any scientist will tell you, a single molecule makes all the difference.
Even if 1 test is technically a steroid, it isn't a very effective one.
I used Pat Arnolds 1 test and thought it was utter crap. Bill Llewelyn was trying to convince me how great his formula was and wanted to send me some bottles. I told him flat out, if it worked, I'd say so, but if it didn't, I'd say so.
He never sent it.
