Norephedrine : Also known as Phenylpropanolamine (PPA) - is a drug ingredient of the phenethylamine family used as a decongestant in prescription and nonprescription (over the counter) cough and cold, and sinus remedies, and some combination allergy medices.



L-Norephedrine HCl is an alkaloid stimulant next to pure amphetamine in potency yet unlike normal ephedrine it tends not to elevate the heart rate or blood pressure to the same degree. This product has a much longer half life, which means that it stays in the system for longer, and can have a much higher appetite suppressing effect than ephedrine. L-norephedrine has also been shown to some extent to elevate mood and positive feelings of well being making this a further bonus to the harsh dieting often experienced in many athletic sports, especially body building.

Norephedrine has been around for a while but as a mixture of two isomers - the same atoms in two slightly different arrangements. The mixture is called phenylpropanolamine (PPA) and is also found in appetite suppressants such as Dexatrim. In particular it is the 1R, 2S isomer which is of particular effectiveness.


An effective dose generally being 25mg 2 - 3 times per day. Of course this substance should be used for periods of dieting or weight loss and it's use should be cycled of used infrequently.
