Intervention model description: This study will include separate single- and multiple-dose parts.

Single-dose part:

A double-blind, placebo-controlled, randomized, sequential-group design with 5-MeO-DMT administered by intramuscular injection in 6 cohorts of 6 subjects (randomized as 5 active and 1 placebo subject(s) per group).

Multiple-dose part:

A double-blind, placebo-controlled, randomized, sequential-group design with 5-MeO-DMT administered by intramuscular injection in up to two doses within a single day (3-hour interval) with two different dose levels (6 subjects per group).
Primary purpose: OTHER

Brief summary: The primary objective of the study is to assess the pharmacokinetics, safety, and tolerability of a single-dose and multiple-doses of 5-MeO-DMT administered by intramuscular (IM) injections in healthy subjects.

Detailed description: This study is a phase 1, first-in-human, double-blind, placebo-controlled, randomized, single-dose and multiple-ascending-dose study of 5-MeO-DMT administered by intramuscular injection in 54 healthy subjects (adult male and/or females, 18-65 years of age). Subjects will be randomized 6:1 to receive 5-MeO-DMT or placebo.

Eligibility criteria: Inclusion Criteria:

* Healthy adult male or female.
* Aged at least 18 years but not older than 65 years, inclusive.
* Body mass index (BMI) within 18.0 kg/m2 to 32.0 kg/m2, inclusive.

Exclusion Criteria:

* History of significant hypersensitivity to the IP or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs.
* Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, or endocrine disorders, as determined by the investigator (or designee).
* Participants who, in the opinion of the investigator (or designee), should not participate in this study.
* Participant is participating in another study with a medical device or IP within the last 30 days prior to first study drug administration.
