Premium 1FE-LSD – Lab-tested quality & transparency
Discover our carefully curated selection of 1FE-LSD (1-Fluoroethyl-Lysergic Acid Diethylamide) – a lysergamide derivative that meets the highest purity standards for research purposes. Each product is tested by independent laboratories and comes with full Certificates of Analysis (COA).
What is 1FE-LSD?
1FE-LSD is a structural analogue of LSD and belongs to the lysergamide class. The substance is characterized by its chemical stability and defined molecular structure. As a prodrug, 1FE-LSD is metabolized to LSD in the body, making it particularly interesting for scientific research applications.

Frequently asked questions about 1FE-LSD
How is 1FE-LSD delivered?
All products are shipped in light-protected, airtight packaging to ensure maximum stability. Delivery is discreet and secure in neutral packaging.
What is the purity level of 1FE-LSD?
Our products have a purity of at least 98%, confirmed by independent laboratory analyses. A Certificate of Authenticity (COA) is available upon request or directly with the product.
How should 1FE-LSD be stored?
Store the product in a cool, dry place, protected from light, at temperatures below 20°C. Ideally, store it in an airtight container in the refrigerator. To maintain stability, avoid direct sunlight, moisture, and heat.
What is the difference between 1FE-LSD and other LSD derivatives?
1FE-LSD differs from 1P-LSD by the presence of a fluoroethyl group at position 1. This structural modification makes it a prodrug that is metabolized to LSD in the body. Compared to 1P-LSD or 1cP-LSD, 1FE-LSD offers similar properties with slightly different pharmacokinetics.
Is 1FE-LSD legal?
The legal situation varies by country and region. In many countries, 1FE-LSD is not subject to the same regulations as LSD itself. Please inform yourself about the applicable regulations in your country before ordering. We only ship to countries where possession is legal.
What is the dosage for 1FE-LSD?
Our 1FE-LSD blotters are precisely dosed and come with exact instructions. The dosage is comparable to LSD, but the body's conversion process must be taken into account.
