Oh don't get me wrong, this isn't real clen, it's an OTC supplement with a bunch of different stims in it.
Frankly, I love it! I have taken a few 1/2 and full-doses just for energy at work, I have not used it to cut or to try to affect my weight. I can compare the stimulant effect to the original Lipo 6, that's what it reminds me of. Mainly physical energy, a little bit of jitters, and a little mental stimulation as well. Not as physically effective as Redline or Lipo 6 Black, and not as mentally effective as XForce or LG Speed.
At the moment I am taking a break from stims, perhaps I will play with the dosages a little once I get back to using stims, and see what effects I can get. I've always been a human guinea pig!
