I don't remember, my newbie gains were so long ago. Probably between 1 and 3 months is when I saw my first ~1 inch or so of bone-pressed erect length gains. More recently I gained ~0.75'' or so in bpfsl between feb 2011 and april 2011 (I think that was roughly the time frame, I remember trying to pack on some quick gains before I went to California for a week with my now-ex-girlfriend and her family).
