1. Structure: LSD with a fluorine atom added to the 1-position nitrogen.

2. Effect: Believed to metabolize into LSD in the body, so effects are reported as nearly identical to LSD-25. Typical dose range users report is ∼100-150mcg, similar to LSD.

3. Onset/Duration: ∼30-90 min onset, 8-12 hours total, like classic LSD. 1fe lsd

1. Research chemical: No human safety studies, no quality control. What’s sold as “1F-LSD” isn’t verified unless lab tested.

2. Set & setting: Same risks as LSD – can trigger anxiety, panic, or lasting psychological effects, especially with personal/family history of psychosis.

3. Interactions: Dangerous with lithium, SSRIs, tramadol, stimulants.

4. Not medical advice: If you’re considering using any psychoactive, talk to a medical professional about risks with your health history.

What is 1Fe-LSD?

1Fe-LSD is a research chemical that can turn into LSD in the body. The effects are similar to classic LSD, such as stronger perception, visuals and deeper thoughts.

It is slightly less strong per microgram than 1S-LSD. That is why these blotters contain 200µg. This gives a similar overall experience to a 150µg 1S-LSD blotter.

What makes these blotters stand out?

Each blotter is made in a professional lab and carefully dosed. This means you know what to expect every time.

The experience is often described as clear, smooth and long-lasting. Compared to products like magic truffles or shroom drops, blotters usually last longer and feel more stable.

If you are looking for a lower, more controlled experience, you can choose 1Fe-LSD micro pellets instead.
