slang for the hallucinogenic drug AMT or Alpha Methyl Tryptamine, now scheduled in the US since 2004 but long prior available over the internet thru various suppliers.

AMT is unique in that in addition to its hallucinogenic properties it is also known to be a MAOI or Mono Amine Oxidase Inhibitor.

dosage is usually 25-75mg. Anything more than that is foolish. it is commonly compared to LSD but actually is closer chemically to psilocibin or DMT.

the length of the experience is a whopping 18 hours, and even then one may notice residual effects such as visual distortions and other perceptual alterations of the drug.

The MAOI effects mean that, in addition to the dubious "benefit" of potentizing other psychedelics, it may also potentize speed and other compounds to the degree necessary to cause fatal overdose symptoms from an otherwise normal amount.

In addition, MAOIs carry with them a severe dietary restriction against eating foods rich in the amino acid Tyrosine.

One might induce a nasty headache or worse from drinking or eating any of the foods those taking MAOIs are generally restricted from.

Eating of these foods while on medically prescribed prescription strength MAOI's can cause death.

The leader, or dominant individual, or pair, in a pack or group of people. The alpha may be male or female, or both as a pair. This distinction comes from studies of African wild dogs and their behavior. In many cases, the female is more dominant than the male and keeps her alpha position for the remainder of her life, whereas the alpha male's position changes often. Beta males tend to compete for the alpha position, especially among large dog packs.
Women want men to be alpha when they date to ensure that a man is capable of leading a relationship. We can learn a lot for wild dogs in our dating relationships. Be an Alphadog.
