Helladrol kicked in pretty nicely on the third week for me. I went from feeling a little hotter each day to just wanting to pound everything in the gym on the 3rd week. Saw about 3-5 lbs gain on 3rd week, by the time I was done with 5 week cycle and PCT, I had about 7lb lean mass gain. I recommended it to all my friends who were all super skinny Asian guys and they all had about 10 lb mass gain.
2nd and 3rd cycle of Helladrol did nothing for me though.
