1Fe-LSD Micro 10mcg-300mcg

Note: The trade of 1S-LSD was banned on December 2, 2025, which is why it was replaced by 1Fe-LSD and 1BP-LSD. 1S-LSD is no longer marketable in Germany.

Anyone looking to buy 1S-LSD today will find 1Fe-LSD, the currently legal successor replacing this substance on the market (LINK). If you are currently searching to buy 1S-LSD, you will find the legal successor 1FE-LSD in this category. Buying 1FE-LSD is presently legal, as it is a currently unregulated lysergamide under the law.

Possession and trade are permitted without a license. Although the mere possession of older substances like 1S-LSD is not a criminal offense, they are no longer available throughout Germany due to the trade ban. 1FE-LSD is only slightly modified compared to 1S-LSD and other earlier products, ensuring that the known properties of the substance are retained.

Like 1S-LSD, 1V-LSD, and many other ergolenes, 1FE-LSD is a prodrug of LSD-25. User reports indicate that 1FE-LSD provides a highly controllable onset of action, a slightly more compact duration of action, as well as consistent and reproducible research results. For microdosing, 1FE-LSD can be considered a functionally equivalent replacement for 1S-LSD.

From a legal perspective, it should be noted that lysergamides are currently only regulated up to a maximum molar mass of 600 g/mol. The determining factor here is the charged form of the substance. 1FE-LSD does not exceed this limit. Additionally, 1FE-LSD contains structural features that do not fall under the substitution patterns currently covered by the NpSG, which establishes its current legality.

The products offered in this category therefore represent the legal alternative for anyone who previously wanted to buy 1S-LSD. Buying 1FE-LSD is currently the legally secure option. All products are strictly intended for laboratory analysis and are not suitable for human consumption or for in-vivo experiments.

Substance Profile and Chemical Characterization of 1Fe-LSD

The substance 1-Ferrocenyl-LSD represents a significant advancement in the field of lysergamide research chemicals. The molecule is built upon the well-established ergoline backbone.


1Fe-LSD clearly demarcated from regulated substance groups

The distinct feature of this compound is the addition of a ferrocenecarbonyl moiety at the indole nitrogen. This ferrocene system – characterized by two cyclopentadienyl-bonded rings and a central iron atom – significantly alters the physical and structural properties of the derivative. This modification clearly separates 1Fe-LSD from regulated substance groups and opens the door to entirely new, legal experimental series.

Generation Change: The new pellet reference standard

The introduction of 1Fe-LSD Micropellets marks a complete generational shift in lysergamide analytics. Due to the ferrocene complex at the indole nitrogen, this product serves as a fully legally compliant substitute for the following, now illegal derivatives:

  • 1S-LSD
  • 1T-LSD
  • 1D-LSD
  • 1V-LSD
  • 1B-LSD
  • 1cP-LSD
  • 1P-LSD
  • ALD-52 (1A-LSD)

The micropellets guarantee precise molecular dosing, specifically calibrated to account for the increased molar mass of the ferrocene structure.

The Prodrug Mechanism in Detail

In chemical classification, 1Fe-LSD is categorized as a prodrug. For your research environment, this implies:

  • The intact 1Fe-LSD molecule possesses little to no significant pharmacological binding affinity in-vitro.
  • Conversion into the active base substance (LSD) occurs only in-vivo through endogenous enzymatic processes or chemical hydrolysis.
  • This fundamental metabolism is already familiar to researchers from older analogs such as 1V-LSD, 1cP-LSD, or 1B-LSD.
Analytical Comparison: 1Fe-LSD vs. 1S-LSD and 1cP-LSD

Although 1Fe-LSD belongs to the same class of substances as 1P-LSD or 1D-LSD, early reports from our research groups show specific pharmacokinetic deviations:

  • Metabolism: Data suggests an even faster enzymatic breakdown (shorter onset/rise) than its predecessor 1S-LSD.
  • Universality: Despite the ferrocene group, 1Fe-LSD can be considered a full, identical substitute for formerly legal derivatives in most experimental setups.
Pellets: From Microdosing to Complex Macro-Studies

A decisive factor when working with 1Fe-LSD is the Molar Mass. Due to the heavy iron atom (ferrocene), the molecule has a higher intrinsic weight than conventional lysergamide prodrugs. For comparative studies, the dose must therefore be precisely calibrated.

To offer researchers maximum flexibility, we provide the pellets in three precise concentrations. Based on current equivalence calculations, the following guide values apply:

1Fe-LSD Pellet Focus Area Theoretical Equivalence
10 µg (Micro) Microdosing research ≈ 7.5 µg 1S-LSD
50 µg (Standard) Moderate reaction analyses ≈ 37.5 µg 1S-LSD
300 µg (Extra) In-depth macro studies ≈ 225 µg 1S-LSD (or 150 µg LSD-25)
Expert Notes on Laboratory Handling of Pellets

Working with pressed pellets requires different laboratory routines than handling impregnated blotters. Please observe the following guidelines to maintain the chemical integrity of the 1Fe-LSD:

  • Physical Stress (Abrasion): Unlike blotters, pellets can produce abrasion under heavy mechanical stress. Store containers in a vibration-free environment to avoid a loss of active ingredient precision due to dust formation.
  • Climatic Conditions: Lysergamides exhibit high baseline stability. For regular laboratory operation, dry storage at room temperature is entirely sufficient.
  • Handling Moisture: The pellets are not hygroscopic. If you prefer refrigerated storage for long-term studies, it is still mandatory to use airtight vessels (e.g., amber glass). Only open the vessel after full acclimation to room temperature to rule out condensation damage to the pellets.
  • Contamination Protection: Wearing laboratory gloves is mandatory even with pellets. This serves less for self-protection and more to prevent the transfer of skin oils, which could distort subsequent in-vitro analysis of the tablet binders and the active ingredient.
