Phentermine comes in either capsules or tablets in several colors with three different strengths: 15, 30 and 37.5 mg. It should be noted that Phentermine is a short term management drug that is not meant to be used for an increased period of time. It is said that after just a few weeks, the body can build a defense against the drug and cease to work properly.
The way that Phentermine functions is by using the central brain mechanism to suppress appetite. Because of the strength Phentermine is known to have, we recommend that it be the only appetite suppressant taken at the time of consumption.

Phentermine is still available by itself in most countries, including the U.S. However, because it is similar to amphetamines, it is classified as a controlled substance in many countries. Internationally, phentermine is a schedule IV drug under the Convention on Psychotropic Substances.

Generally, phentermine appears to be relatively well tolerated.[5] It can produce side effects consistent with its catecholamine-releasing properties, e.g., tachycardia (increased heart rate) and elevated blood pressure, but the incidence and magnitude of these appear to be less than with the amphetamines. Because phentermine acts through sympathomimetic pathways, the drug may increase blood pressure and heart rate.
