Question: what is the difference in phentermine and phendimetrazine?
Answer: Bontril PDM (phendimetrazine) can help you lose weight, but can't use for long periods of time and isn't for everyone. Adipex-P (phentermine) is effective at lowering appetite and helping with weight loss. Available in generic form, which is more affordable. You only need to take it for a short period of time.
