DPT HCl. (Dipropyltryptamine) Powder

---

N,N-Dipropyltryptamine (also known as Dipropyltryptamine, DPT, and "The Light") is a lesser-known psychedelic substance belonging to the tryptamine class. It shares a close relationship with DMT and is noted for its unique hallucinogenic intensity, which is accompanied by a moderately longer duration and greater unpredictability compared to DMT and other psychedelic tryptamines.

History and Human Use

DPT was first synthesized in 1950. The first reported human use occurred in 1973, where it was studied in low doses as an adjunct to therapy for alcoholism. Additionally, high doses of DPT have been researched to induce peak experiences in terminal cancer patients. The substance has gained notoriety for its role as the primary sacrament for the "Temple of the True Inner Light," a Christian offshoot in the United States that advocates for the ritual use of psychedelics, referring to them as "the true flesh of God."

Methods of Consumption

DPT is typically consumed through insufflation or orally. Users often report that insufflation can be congestive and painful, with the rapid onset leaving little time to adjust to its powerful effects. Other methods of administration include intramuscular injection or vaporization after converting it to its freebase form. Smoking the freebase is a preferred method among members of the "Temple of True Inner Light," while more experienced users may opt for DPT tea.

Chemical Structure

DPT, or N,N-dipropyltryptamine, is a synthetic indole molecule within the tryptamine class. Tryptamines are characterized by a core structure that consists of a bicyclic indole heterocycle, which is attached at R3 to an amino group via an ethyl side chain. DPT features two propyl group carbon chains linked to the terminal amine RN of its tryptamine backbone.

Substituted Analogs

DPT has several substituted analogs, including 4-HO-DPT and 4-AcO-DPT.

Mechanism of Action

Research conducted on rodents indicates that the effectiveness of a selective 5-HT2A receptor antagonist in blocking the behavioral actions of DPT suggests that the 5-HT2A receptor plays a significant role in its effects. Additionally, the modulatory actions of a 5-HT1A receptor antagonist imply that there is also a 5-HT1A-mediated component to DPT's actions. The precise nature of these interactions and their contribution to the psychedelic experience continue to be the focus of ongoing scientific research.

Comparative Effects

In comparison to other psychedelic tryptamines like DMT, DPT is often reported to have a similar hallucinogenic intensity but with a longer duration. Users frequently describe DPT as being more sensual and physical than DMT and other psychedelics, which can lead to a corresponding increase in adverse physical effects.
