Hey rocco, I'm in week 4 of my test/tren/mast cycle. 100mg EOD like you. masteron is pretty mild, as far as strength and size gains go I'd say they won't be a whole lot, but I think the masteron supposedly enhances the effects of Test. Really you see the benefits of masteron at lower bf%, personally I am seeing a ton of vascularity and it's keeping the water off of me very well. It's my first time on Tren AND Mast though so I can't totally attribute which gain to which compound, but as far as I can tell, it's pretty good stuff. No MPB in the cards for me, so I haven't noticed anything in that category either.
