Snortin' Andro

There’s a company making a nasally inhaled 4-diol product I was curious about. This is how the east germans originally used andro during the olympics. My question is would it be more usefull to an athlete to use this an hour before his event, or to use androsol twice-a-day. Also, as strictly performance enhancement, would you need to use androsol for a couple of days before the event for maximal effect, or is one day ahead good enough. Thanx, Lain.
