Beware is all I can say.
It is IMPOSSIBLE to tell if you're being sent MT1, MT2, HCG, HGH, or any other similar white wafer in a tiny vial.
My personal experience: I purchased MT2 (or was called MT2) from SL about >6 months ago. Great price..they're a decent sized research company and swear they know their shit. Well, I know mine and what I got caused a disgusting discoloration I have NEVER experienced with real MT2 over years of use. It took me another 6 months for the dark spots around my mouth to fade. It was really embarassing for a while. But even though I stopped taking it as soon as I noticed darkening, it was too late and the symptoms apparently had to run their course. Also, libido improvements? nada. So my impression was I got a junk version of one of the MT options and it certainly wasn't what I wanted.
IF you get the right thing, it will give you an amazing tan and improve libido drastically....but with the lack of quality control and sneaky importation required for the research companies to get their supplies, I doubt anyone really knows or cares what they're sending out. Nobody still in business tests their supplies, and the only company I knew of that did such a practice got shut down years ago. Beware with your purchases~
