In all honesty, if you're not extremely experienced with Penis Enlargement'ing you don't really need to worry yourself with finding your lot number. As long as you're still gaining from your routine there's no reason to switch things up, right?
I never was concerned with my LOT number, and ignored all hype about it.
End of the day, if you PULL ole tobbie he will grow, no matter what ya LOT is.
The penis HAS TO grow from this, it may take time for some .. but itll come.
Ignore the LOT and carry on with a clear head.
