I'm not really sure about taking them together. I'm reading MT2 is better for the tanning effect and PT 141 is better for libido (with slight tanning sides), but I believe they have a very similar mechanism of action so I'd assume you'd be one super tan libido to the extreme dude for a bit lol. I heard the nausea can be somewhat of an issue with the PT 141 as well, so I'm going to be cautious of that if/when I give it a try.
