How quickly is phentermine effective? Does taking phentermine for small periods of time (1 wk) show reults?

Answer 1

If you have a lot of weight to lose it would give you results in a week.
You can feel it working the first day. I lost 18 lbs my first month on it.
But it's meant to be taken for 6-12 weeks at a stretch.

Answer 2

I've been taking it for 6 days and have already lost 10 pounds! I assume it's all water weight but I don't care - I'm excited can't you tell?!
