I didn't say its lost its effectiveness after a "couple" of times. I've been "on" for over 1 yr now...creatine mono, V12 turbo, creatine mono, satur8, creatine mono, Fizogen Blitz cycle, creatine mono. Thats how its been this past yr and it just seemed this last time around I wasn't seeing quite the results as i was before but maybe its cuz i went from blitz cycle back to plain ole mono....i dunno?? Maybe i'm just getting used to it and have forgotten what its like 2 be w/o it?? I do know though, i'm not as good a responder to it as lots of people r. Just thought i'd ask your guys opinions. Thanks
