Phentermine Types

Phentermine is not a trademark name like Adipex. It is simply the chemical name for the medicine in the pill. This makes all types of Phentermine generic drugs. Because Phentermine is a generic drug, there are numerous manufacturers of Phentermine.

Which brand is best?

There is no answer to this question because all Phentermine sold in the USA is required by the FDA to be manufactured within a tight tolerance. This helps control the quality of the product.

How Do I Know I’m Getting FDA-Approved Phentermine?

First off, it’s essential that you avoid online pharmacies that primarily sell generic drugs. You should also avoid sites that sell order counts higher than 90ct. If a company sells 180ct of Phentermine, I usually hear customers who say their order arrived in an envelope with a baggie in it; with handwritten shipping info and an address from India.

Difference between blue and yellow phentermine ?

Here is the laymans answer as we understand it. For a more technical explanation, please contact the manufacturers Eon Labs and Purepac.

The yellow phentermine 30mg capsules and the blue Phentermine 30 mg capsules act the same. Blue Phentermine and Yellow Phentermine both have the same active ingredient (i.e. Phentermine Hydrochloride). There is no generic equivalent for Ionamin, which is the timed release resin form of Phentermine.

Both of these capsules are manufactured by Eon Labs. The blue/white version is a generic for Fastin and the yellow is just a generic phentermine. The ingredients are the same. The only real difference is the price per pill.

As for the 15 mg capsules, they are simply a lower dosage form of Phentermine that is manufactured by Eon Labs.
The 37.5 mg Phentermine is a generic for Adipex-P that is manufactured by Purepac. The only difference between the brand name (Adipex-P, manufactured by Gate Pharm) and the generic is price.
