Phentermine diet pills? Is it a fast way to lose weight?

Phentermine diet pills? Is it a fast way to lose weight?

No: I would strongly avoid any and all dietary supplements as they will not provide long term weight loss and could possibly even be harmful.

Those who look to pills even to "help" with weight loss usually are not truly ready for making the changes necessary for long term weight loss success. ...Read more

How long will the over-the-counter diet pill fastin (phentermine) test positive in you urine?

How long will the over-the-counter diet pill fastin (phentermine) test positive in you urine?

Good luck!: I show the generic (phentermine) still as a prescription-only medication. So, whatever is in the over-the-counter version is not likely its true namesake, or potentially in a very reduced strength--either of these may not give you the results you are hoping for, and toxicity risk. Phentermine can show in urine drug screen for 10-14 days per internet resources. ...Read more

? Question: Your question is incomplete but I am assuming you want to know if 5HTP causes weight loss. It, s action is indirect. Your first statement is correct as people develop tolerance to phentermine over time. 5HTP is a tryptophan derivative which is converted to serotonin in the brain. Serotonin works to prevent you from getting hungry. Avoid if on certain medications and consult your doctor before use. ...Read more

Not recommended: Phentermine is an appetite suppressant that has a 99 percent failure rate---long term. Yes it works when you take it but weeks later the weight starts returning. Vicious cycle. Pcos is a pre-diabetic state so a good diabetic diet and exercise is your best choice. Metformin is a medication used for to improve Insulin receptors and can help. Talk to your doc. ...Read more
