Get the MDPV mug.
A variant of mdpv created by John Mcafee the creator of mcafee antivirus.

Tan, also known as "super perv powder" makes you extremely horny and paranoid. It was created around 2012 after mcafee moved to Belize to presumably escape legal troubles and to develop a drug with 31 year old ethnobotanist Allison Addonizio called quorumex. He posted about his findings on a popular drug forum called under the username Stuffmonger.

Examples of Tan mdpv being talked about in a sentence by John Mcaffee are as follows:

"Measure your dose, apply a small amount of saliva to just the tip of your middle finger, press it against the dose, insert. You will be well rewarded."

"I will not, anymore, let anyone on Tan be alone with my dogs for example. (I have 14 dogs). Twice in the past year Tan users (one man, one woman - both after major massive doses, to be fair), attempted to have sex with one of my dogs."
