I have been on REM, cycled of course, since the beta version...it is the TRUTH!!! :thumbsup: You definitely cannot go wrong with it. It starts working from the first dose...honest. The sleep is phenominal even if it is only like 4 hours; it enhances recovery and aids in lean mass retention during my cuts. For the sake of sounding like an infomercial I will stop but it really does kick a$$!!!
As far as Lean Dreams is concerned during some down time on the REM, I used some samples of this. It also provided some d*%n good sleep but I only used it for almost a week so my experience is limited. However, its effects were good during my short trial.
I would venture to say that you cannot go wrong with either product but because I am a USP whore and I have been on REM 4eva, I definitely recommend it without hesitation.
