1P LSD
1P-LSD, also known as 1-Propionyl-D-lysergic acid diethylamide, is a research chemical closely related to LSD (lysergic acid diethylamide). It has become popular among psychedelic users as an alternative to LSD because of its similar effects and, in some regions, its legal status.
As a prodrug, 1P-LSD is inactive until it is metabolized by the body, where it converts into LSD and produces the classic psychedelic effects.
If you are looking to buy 1P LSD blotter, buy 1P LSD, or find 1P LSD for sale, it is often sought after by enthusiasts for research and personal exploration.
In this article, we cover everything you need to know about 1P-LSD, including its chemical structure, effects, safety, and legal considerations.
Is 1P-LSD Legal?
- United States: Currently, 1P-LSD is not explicitly scheduled at the federal level. However, it may be treated as an analog of LSD under the Federal Analogue Act, which could make it illegal.
-
European Union: In countries such as the UK, Germany, and France, 1P-LSD is regulated under analog laws. This makes its sale, purchase, and possession illegal.Other countries, like Switzerland and the Netherlands, have more relaxed rules, often allowing research or limited personal use.
- Canada: 1P-LSD is not specifically listed under the Controlled Drugs and Substances Act. However, analog provisions could classify it as illegal.
-
Asia and Other Regions: Countries like Japan and Singapore have strict drug laws that may classify 1P-LSD as illegal.In some regions, no specific laws exist regarding 1P-LSD, creating a legal gray area.

Effects and Experiences: What to Expect
- Visual distortions – Colors may appear more vivid, with users reporting intricate patterns, fractals, or closed-eye imagery.
- Auditory changes – Sounds can feel amplified, while music often reveals new layers of depth and complexity.
- Cognitive and emotional shifts – Users frequently note increased creativity, feelings of euphoria, and powerful self-reflection. Some also describe moments of spiritual awareness or emotional release.
- Time perception – Time may feel stretched or compressed, creating an altered experience of its passage.
The effects usually last anywhere from 8 to 12 hours, with the peak experience taking place about 2 to 3 hours after ingestion. While many people find the effects enjoyable, higher doses can sometimes bring feelings of anxiety, confusion, or even being overwhelmed. For those exploring natural options like reishi mushroom tea or reishi mushrooms tea, it’s important to be mindful of dosage and personal tolerance.
The Safety Profile of 1P-LSD
When used responsibly, 1P-LSD is often regarded as relatively safe. However, like other psychedelics, it carries potential risks. Since there are no long-term clinical studies, its complete safety profile remains uncertain. Still, it is chemically similar to LSD, which has been researched in detail.
Possible side effects include:
- Nausea: Common during the early stages but usually fades within the first hour.
- Anxiety or paranoia: Higher doses or an unsettled mindset can sometimes lead to panic or distress.
- Elevated heart rate and blood pressure: The cardiovascular system may be stimulated, which can be risky for those with existing heart conditions.
Using 1P-LSD carefully is essential, especially in new environments or without supportive company. Mindset, dosage, and surroundings all play a major role in creating a safer experience.
Because the substance is typically unregulated, its purity and strength can vary. This makes it important to obtain it from reliable sources.

1P-LSD vs. LSD: Key Differences
- Potency: 1P-LSD is usually slightly less potent, so a higher dose may be required to reach effects similar to LSD.
- Duration: The experience often lasts longer, with reports of up to 12 hours, compared to LSD’s typical 8–10 hours.
- Onset: Some users notice a slower onset with 1P-LSD, likely due to the time needed for the body to process it into active form.
How is 1P-LSD Used?
- Dosage: A normal range is 50 to 150 micrograms. New users should begin with smaller amounts, while more experienced users sometimes take higher doses.
- Onset: The first effects typically appear within 30 to 60 minutes. The peak usually happens about 2 to 3 hours after taking it.
- Safety Tips: For safer use, choose a familiar, comfortable setting and have a trusted friend present. Drink water, avoid alcohol or drug mixing, and rest if the effects feel overwhelming.
Start with a low dose and ensure a safe, supportive setting. Understanding both physical and psychological risks will help make the experience safer and more meaningful.
