So I recently had to dump 2 bottles of Masteron from a recent source that got sloppy and my shit had crap floating in it. Of course he's not here anymore so I took an L. Well, I placed an order with MP to grab an extra vial to replace one of the two I dumped because I really only needed one more. Mp caught wind of this because I was telling someone about it and damn if he didn't throw in an extra Mast for me because of what I lost! Mp is a great source with great gear who apparently knows a thing or two about customer service. Thanks Mp!!
