    I have been reading posts by a select few for over a decade and half when RGEN
    was still making drugs. I, like a couple of you, have been holding on for years. I was the proud owner of
    2000 shares purchased close to $4.00 and only when it hit $190.00 did I sell 600 shares. I , once again,
    like a couple of you, have sat thru some antagonizing drops in share price , enough for me personally to
    question my own sanity. After all these years of reading posts, I am finally letting you guys know, I've been
    their all the way.
