A-PHP or alpha-Pyrrolidinohexiophenone (also known as PV-7, alpha-PHP, A-PHP, and α-PHP) is a lesser-known novel substance from the cathinone class. It is structurally related to compounds such as MDPV and is one of the successors to the designer drug cathinone analog A-PVP.
A-PHP is very new, and will come in the form of either a fine powder or crystal, which when tested, produce powerful but short-lived euphoric effects which are similar to methamphetamine when inhaled by the test subject.
Vaporizing A-PHP is a common method of researching. Vaporizing A-PHP gives more control over temperature because the flame or heat source does not come into direct contact with the substance.
