ALD-52 Dosage and Use

Because ALD-52 is potent even in microgram quantities, it should be approached carefully.
Typical ALD-52 dosage ranges:

Microdose: 10 to 20 µg (for focus and creativity)

Standard dose: 75 to150 µg (for full psychedelic effects)

High dose: 200+ µg (for intense, immersive experiences)

Product Characteristics

ALD-52 is a distinct chemical compound within the lysergic-acid/LSD class.

The name 1-Acetyl-LSD describes its chemical relationship to LSD. ALD-52 should not simply be treated as another name for LSD itself.

Physical appearance alone cannot establish the identity, purity, concentration, or composition of an unknown chemical sample.

Classification

Health Canada places ALD-52 within the hallucinogen — lysergic acid (LSD) class in its published new psychoactive substances information. The same source describes ALD-52 as an LSD analogue associated with psychedelic effects resembling those of LSD.

General Product Information

ALD-52 is also identified in U.S. government substance-registration records under names including:

• ALD-52
• 1-Acetyl-LSD
• 1-Acetyl lysergic acid diethylamide
• Acetyl lysergide

These names refer to the same registered substance.

Safety Note

ALD-52 belongs to the psychedelic/hallucinogen class. Health Canada describes LSD-class substances as capable of producing psychedelic effects and notes that new psychoactive substances can have limited available safety information.

The appearance or labeling of an unknown chemical should not be treated as laboratory confirmation of its identity or purity.

Regulatory Information

Regulatory treatment of ALD-52 can vary by jurisdiction and can change over time.

Health Canada’s 2022 publication listed 1-Acetyl LSD (ALD52) as “Not controlled” in its table of new psychoactive substances. That publication should not be treated as a guarantee of the current legal status of ALD-52, particularly because Canadian controlled-substance regulations have subsequently changed and continue to be updated.

For a current determination, consult the applicable Canadian legislation or Health Canada’s Office of Controlled Substances.
