1D-LSD
Dosage & Duration
Dosage
Doses are population estimates that vary widely between individuals.
1D-LSD functions as a prodrug that is converted to LSD in the body, so dosing guidelines are derived from this metabolic relationship.
Duration
Subjective Effects
Legacy content. A statistically backed ontology from Mindstate Design Labs is coming soon.
Effects vary widely by individual, dose, and context.
Physical
Cognitive
In comparison to other psychedelics such as Psilocin, LSA and Ayahuasca, 1D-LSD is significantly more stimulating and fast paced in terms of the specific style of thought stream which it produces and contains a large number of potential effects.
Visual
Geometry
The visual geometry of 1D-LSD can be described as more similar in appearance to that of 2C-B and the 2C-x family than psilocin, LSA, or DMT. They can be comprehensively described as unstructured in organization, algorithmic and digital in geometric style, intricate in complexity, large in size, fast and smooth in motion, multicoloured in scheme, bright and flat in colour, and sharp in their edges with extremely angular corners. At higher dosages they consistently result in states of Level 7A visual geometry.
Hallucinatory States
1D-LSD is capable of producing a full range of low and high level hallucinatory states in a fashion that is significantly less consistent and reproducible than that of many other commonly used psychedelics.

Pharmacology
Dangerous
Highest riskThese combinations are considered extremely harmful and should always be avoided. Reactions to these drugs taken in combination are highly unpredictable and have a potential to cause death.
Unsafe
AvoidThere is considerable risk of physical harm when taking these combinations, they should be avoided where possible.
Caution
Use cautionThese combinations are not usually physically harmful, but may produce undesirable effects, such as physical discomfort or overstimulation. Extreme use may cause physical health issues. Synergistic effects may be unpredictable. Care should be taken when choosing to use this combination.
