No, but it did build fat easier for me. One should monitor intake a bit closer IMO. I wasn't so impressed at gains as I was at the astounding strength increases. The plan was to alternate my strength with HST for gains. (MORE gains)
Then work happened and everything went to crap. Can't lift when doing 60-72 hrs a week, physical. I still think it's the best plan, and BTW, I had to close down caloric intake in the 5's with HST too.
