Isn't that an Australian website though? All looks a bit ropey to me.
edit: also, this copy from the website is infested with bullshit:
'Recently 20 pills were sourced from different suppliers in major cities in Australia. The pills were tested and only 5 contained any ecstasy. The other pills contained various combinations of heroin, ketamine, methamphetamine, LSD and 2-CB, as well as other unidentified substances. Apparently this is the case all over the world. That's a 75% chance of you swallowing a possibly very dangerous pill! For about the cost of one or two pills you can buy a test kit and be a lot safer!'
Could see how meth might have been present but heroin ffs?
