Ok so you can judge a product by its ingredients and looking at the ingredients, it seems this is not a supplement anyone should take as the ingredients are worthless at best and potentially dangerous. Here is what I found for Duzoxin:
Guarana Extract,Garcinia Cambogia, White Willow Bark, Propietary Blend, L-Tyrosine, Citrus Aurantulum,Ginger Root, Pantothenic Acid, L-Carnitine, Magnesium Phosphate Other Ingredients Magnesium Stearate, Calcium Phosphate, Gelatin
Guarana - A stimulant with more caffeine than coffee. From this page:
http://altmedicine.about.com/od/comp.../a/guarana.htm
An animal study examined the effect of 14 days of guarana supplementation on fat metabolism in sedentary and trained rats and found that the guarana's fat-burning effect is due to the caffeine content. Decaffeinated guarana extracts had no effect on lipid metabolism.
Garcinia Cambogia (Aka HCA) - This one is potentially dangerous and has shown no effect on weight loss. 3FC did a little writeup on it here:

There is no evidence to show that HCA is beneficial for weight loss, and it can be harmful in some cases. Recent studies have also linked it to liver damage. It is better to wait and see what future research shows before taking it.
White Willow Bark - This one is a pain reliever, similar to aspirin, very similar to aspirin. No weight loss benefits can be attributed to it. Those that have issues that would prevent them from taking aspirin should avoid any products containing White Willow Bark. More information can be found here:

L-tyrosine - This is actually a non-essential amino acid that you get through the foods you eat. There are some people with medical conditions that need to supplement with it but most should not. More information can be found here:
http://www.evitamins.com/healthnotes...tentID=2919008 Here is an excerpt on what they say regarding it:
Most people should not supplement with L-tyrosine. Some human research with people suffering from a variety of conditions used 100 mg per 2.2 pounds of body weight, equivalent to about 7 grams per day for an average-sized person. The appropriate amount to use in people with PKU is not known, therefore, the monitoring of blood levels by a physician is recommended.
Bitter Orange (Aka Citrus Aurantium) - Bitter orange is one of the supplements that Consumer Reports listed as their "Dirty Dozen". Anyone who takes medications that say "avoid grapefruit juice" should avoid bitter orange/citrus aurantium as well. That includes a huge variety from anti-depressants to birth control pills. Here is an article about Consumer reports findings:
http://www.3fatchicks.com/bitter-ora...supplement%20/ here is an excerpt:
Bitter orange might be just as dangerous as ephedra and can cause serious side effects such as high blood pressure, increased risk of heart arrythmias, heart attack, seizures, or even stroke.
