I am also running an UL M1T cycle. I'm about 10 days into it and so far have put on about 8 lbs. but i drink a shitload of water and can tell im holding a lot of it. As far as sides go, i had headaches at night the first 5 days or so but they are gone now. I started at 10 mg. a day but have now bumped it up to 20 mg, and like you i get crazy pumps. Im almost afraid to bend my arms because they might rip. Im starting to see the strength gains and am using 4Derm which i added 4 grams of 4-AD to, so ive got that going for me......which is nice. the bottom line is UL's M1T is some good shit.
