What is 1S-LSD?

1S-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 not listed as illegal in the Netherlands and several other EU countries, which allows it to be sold for research purposes.

What makes 1S-LSD Blotters special?

These blotters are made in a professional lab and carefully dosed. This means you know what to expect every time.

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

Perfect for

  • Research into LSD-like effects
  • Full macrodose experiences
  • Creative thinking and reflection
  • People who want consistent results

Legal Status in Many EU Countries

1S-LSD is a so-called pro-drug — a compound that converts into LSD in the body. While it produces similar effects, it is not LSD itself. Because of its slightly different chemical structure, 1S-LSD is not explicitly listed on the controlled substances schedules of many EU countries. As a result, it can be legally sold and possessed for research purposes in jurisdictions where it has not been banned.

That said, laws can change quickly. Always check your local legislation before ordering or using research chemicals.

Why EU Free Trade Law Does Not Apply

Unlike officially approved food products (such as psilocybin truffles), 1S-LSD is not regulated or reviewed by national food or safety authorities. It is not classified as a consumer good. Because of this, the Mutual Recognition of Goods Act — which allows free trade of legal products between EU countries — does not apply. Even if 1S-LSD is legal in the Netherlands, customs in other EU countries may still seize shipments.

Please do your own research before ordering. We ship discreetly, but international delivery is always at your own risk.

Dosage & Effects

Dosage Microgram (µg) Typical Effects
Threshold 10–20 µg Slight mood lift, enhanced sensory perception, good for sensitivity testing
Light 25–50 µg Subtle visual patterns, introspective mindset, increased creativity — suitable for first-time research
Moderate 75–100 µg Strong visuals, time dilation, introspection; ego boundaries may begin to dissolve
Strong 125–150 µg Deep immersion, intense sensory shifts, likely ego dissolution — research support or sitter advised
Heroic 175 µg and above Potential full ego death, loss of self, powerful non-dual or mystical states — not recommended without extensive experience and a safe, controlled setting

✔️ Reflect after the experience to integrate any insights or emotions.

    At first I was skeptical about the effectiveness of this product, but I had to change my mind. It’s a true psychonaut trip. Colors, shapes, hallucinations, meditations. My only regret: taking two at once; the effects were borderline manageable, but it was still nice. I’d take one or one and a half.

    Very nice effects and feelings – I find you get more of an effect when taken on an empty stomach. I love them on a good couch rotting day.

    Took two for a good journey. Nice n manageable. The customer service team in my opinion are the best people I have ever had to deal with when it comes to a reply. Primal Focus customer support really do help you sincerely and professionally. I have shop around a lot and believe me some companies are so rude. Primal Focus help us all, because they are the ones with the tools. Without them what would we do? Buying truffles, grow kits, mescaline and more from other companies, all we are is a number, and when something goes wrong I have been fobbed off with many excuses, and I do know what I’m doing and what I’m buying. Primal Focus help you, and they want to help you. That’s the difference with these guys. Thank you for helping me 10/10 on all your products.
