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.

Nice effects, good visuals, would recommend !

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 similar to “real” LSD just a bit milder but I liked it a lot. Recommended

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.
