1S-LSD – the new legal LSD-derivative

Strukturformel 1S-LSD

Last updated: 03. July 2024


After the ban of 1T-LSD on June 26th, 1-trimethylsilyl-propionyl-lysergic acid diethylamide hemi-D-tartrate, in short 1S-LSD, is the new legal LSD-derivative on the market.

In the newly revised version of the New Psychoactive Substances Act, lysergamide compounds containing carbon, hydrogen, nitrogen, oxygen, sulphur, fluorine, chlorine, bromine and iodine were banned. However, this version of the NpSG had already been in place since February 2024 and our manufacturer came up with a clever solution. In addition to a propionyl group, which gave 1P-LSD its name, 1S-LSD also contains the trimethylsilyl group, i.e. a compound consisting of carbon, hydrogen and also silicon. This means that the molecule does not fall under the NpSG and therefore remains legal.

Experiences to date

The two substances 1T-LSD and 1S-LSD are very similar in their properties, so we expect the research results to be comparable. The initial results in our team and with our customers are promising. However, as this is a completely new chemical, we always recommend starting research with a very small amount to be on the safe side.

Can I already buy 1S-LSD?

Yes, you can order the new 1S-LSD at any time at, we have enough in stock. Shipping is by DHL and the average delivery time is 2-3 working days.

How long will 1S-LSD remain legal in Germany?

We can’t say for sure, but it usually takes about a year for the German government to include a new substance in the NpSG. So we assume that 1S-LSD will be legal at least until June 2025. With any luck, even longer.
