I have source or two on Ebay I give you , if you PM me . I also have a source a found on Ebay but they have their own website that sells research chemicals, and sells 60 ml liquids of DMZ 15mg per ml and M-Sten 15mg per ml . I 'll have an update in a few days to a week AFTER I receive my first shipment from them and try them both out . If it's legit , you can't go wrong for the potency and price . I LOVE M-Sten myself . Have you noticed it has some unique taste to it ? I can't really describe it , but now that I've had M-Sten from two different sources , I know the taste of it .
