Yuschak used the L-isomer of aspartic acid (called "L-aspartic acid" vs "D-aspartic acid"), so that's what I picked up. I believe that the D-isomer is what the bodybuilders tend to play with. I don't believe that the L-isomer is used in the synthesis of testosterone.

The L-aspartic acid I got was just the acid rather than part of any more complex blend.
