I'll go ahead and chime in with my M1T experience.
I ran a 4 week cycle back in late 2004. It was basic - 20mg/day for 4 weeks, followed by nolva for 4 weeks of PCT. Within 2 days, my nuts were the size of small marbles. By the end of the first week, I was feeling incredibly lethargic all the time, and my appetite had dropped to 0, which is not a good thing when you are trying to bulk. I still managed to force my food down, but it almost came back up on a number of occasions.
I gained about 15 lbs. of water weight. Most of my major lifts saw at least a 20 lb. increase.
As soon as I quit taking the M1T and began PCT, my weight started dropping immediately, and so did the strength. I caught a terrible cold shortly after beginning PCT, although I'm not sure if the M1T had anything to do with that. I rarely get sick though, so take that for what it's worth.
When all was said and done, i.e., several weeks after PCT, I was perhaps 3-4 lbs. heavier. I was able to keep maybe 1/3 of the strength I had gained on cycle. Considering much of the strength was due to the increased water retention, it wasn't a huge surprise to me that I lost a lot of the strength.
I'm not even sure how much of the weight I ended up keeping was actually muscle.
I have about 1.5 bottles of the stuff left from Omega Sports, although I don't know if I'll ever use them.
