Questions about LSD

In the past I have taken LSD a few times, but in all of those times, the visual part of the LSD did not seem to come up. I've had the same problems in the past with 2-cb, where I took around 45mg and only experienced mild visual effects.

A week ago I took 3 tabs of (supposedly) 180ug each, the effects I noticed were very minimal.

So what I' wondering is, could the tabs I took be fake ones, It had the albert hoffman bike image on it (http://payload272.cargocollective.com/1/13/439629/7751020/hoff1.png) and were bought in The Netherlands.

Or do I just have bad luck and does LSD and other psychedelics just not work for me (visually)?
