Recieved my order from Southern Aminos last week. It was fast shipping. The price was great being able to use 2 codes. It came in a USPS plastic bag. I was concerned at first cause I could feel the vials thru the bag, but when I opened it each vial was in its own little hard plastic container & everything was perfect. Reconstituted yesterday & all is very good. I will order from them again. Thankyou.
