Drug info - What type of LSD analog is this?

[Tacitus]

Hello, SWIM have been taking LSD for some years, and lately SWIM has been taking some blotters that seemed to be a different type of LSD, the effects wear very similar, but not the same. For example no visuals were perceived at all, but the psychedelic sensation is still there. Also, it is bitter.

After doing some research SWIM found a friend who bought a group of them and sent SWIM a picture. SWIM can notice that it is not LSD-25, it seems to be an analog, some kind of isomer of LSD. 2 months ago SWIM sent a picture to Erowid but they never answered. And as SWIM has 0 knowledge about chemistry SWIM was not even able to know the proper writing of that molecule in a single line.

Does anyone recognize the molecule?

It is being sold in Buenos Aires, Argentina, and the image on the other side is the typical white guy riding the bycicle.

Any information will be very useful.

Thanks in advance.

Best regards.
