I have done Phentermine and Clen.
I highly recommend not to mix the two.
Phentermine makes you lose weight but also supresses your appetite. This allows ypu not to eat and later your body goes into starvation mode and you start noticing a lose body. It dehydrates your body. However, increases sexual desire and makes you more sexual.
Clen you notice tremors. Your body SLOWLY loses fat and ypu notice your body becoming more solid. This is a slower process then Phentermine. However, with taking phentermin, you gain weight back fast. 10lbs to be exact, which I noticed to be water weight.
Clen, you slowly gain weight back and not as much.
I would NOT mix the two, sode effects were very BAD!!
Mood swing, sexually confused, depress mode and possible suicide thoughts.
If you wish to use both, please take 2 weeks clen and stop, then replace with two weeks phen.
Try this instead of mixing two powerful meds.
Good luck.
