How do the popular weight loss pills measure up to each other? If you were to compare Adipex to Didrex to Ionamin to Bontril to Tenuate, which would be at the bottom of the list? Would you prefer to give a little risk to lose a lot more? Read on.

First let's take Tenuate. When compared to it's Phentermine peers, it is the milder weight loss pill without the risk. Although Tenuate is not as stimulating as Adipex, it helps fight food cravings. In terms of effectiveness and stimulative properties, the next step up from Tenuate are the Phentermines.

The Phentermines come in two flavors. There's Phentermine hydrochloride. And there is Phentermine the resin. Phentermine hydrochloride goes by the brand names: Adipex, Fastin or Phentermine. In fact, Adipex is considered at the top of the brand list.

Ionamine, on the other hand, is a resin. Even though Ionamin has the stamina to keep working well beyond 12 hours, it's not as powerful as Adipex. Although Adipex only puts in 10-12 hours, it works effectively because it's strength is maximized.

For the weight sensitive yet budget conscious consumer, Adipex gives Ionamin a run for the money. Primarily, Adipex is less expensive and has a better track record for combating fat. While, Ionamine is usually more expensive and less powerful, Adipex and Phentermine are highly effective because the dieter will achieve fat loss if they follow the program.

In contrast, Bontril-SR, the brand name for Phendimetrazine tartrate, is allegedly stronger than Adipex. However, patients and users of both prescriptions cannot differentiate between the two in terms of affects and effectiveness. Surveys show that, most people choose one or the other based on price, availability and favorite color. And unlike other different weight loss pills where the patients lack cross-tolerance, there is a high level between Adipex users and Bontril users. The difference here: dieters cannot step up from Adipex to Bontril when Phentermine loses its effectiveness.It's about 50/50 when you compare the pros and cons of Adipex versus Didrex, the brand name for Benzphetamine. Because it is the closest of all the diet drugs currently available in an amphetamine, it explains why it has a greater reputation for abuse than Adipex. The best benefit of Didrex is that it allows the dedicated dieter to take their weight loss program further than Adipex. And that's if you're not looking for a job because Didrex can falsely alter the results in drug testing to positive.

When you tally all the pros and cons, Tenuate is at the bottom of the list. With Bontril and Ionamin in tow, one would think that Adipex is a mere second choice. But Adipex still out performs Didrex, when you compare the complications -- because, Adipex is the safer, less expensive and more effective weight loss prescription
