I got my maxpro Tren-A 100mg 10mm vial from a friend whom actually picked it up in Thiland. This stuff is very clean, very potent, with no pip. 100mg a week is pushing it for me as the aggression is nearly to much. When I am able to take my ADHD medication, im able to run 300mg a week. Results really start showing !! Anyways, There is not just ONE manufacturer out there making maxpro. There are many others.........Lixus brand from Etalaze has a high reputation for being dirty, fake, and even health hazardous causing metal poisioning in people. But Lixus brand from others sources hail great boasting.... Read like your studying for an SAT before you buy from anyone of any product and or brand.
