Any chance you've found the more recent Ganeshas to be a bit less potent than before Matt? Had some in July that blew my head off in comparison to the ones i had last week, less vivid visuals etc although still a great trip! Im guessing its down to how they've been stored...
I thought i'd give a bit of info too for this: When I first took a ganesha I had one tab, I was told these were potent and some people had a good strong trip on them, really nice visuals accompanied it also. But when I got to try them myself I believe I expected too much and as a result had a pretty mild trip, very minor visuals, minor headfuck and my pupils didn't even dilate.
The next week I took one and a half and had a much better trip, had nice enough visuals and really enjoyable music appreciation and even some empathy. Both these trips where in a different setting, I personally feel that tripping outdoors decreases my visuals unless at extremely high doses or with strong psychedelics. Acid affects you differently everytime, it has the same effects but your experience is always different. Try them a few more times if you can and see how that goes, you might've just had an off experience like I did with them.
I personally really enjoy visuals as part of my trip with LSD, I also consider it a good indicator on dosage as I can see how intense they are. I've also taken other psychedelics due to them being described as having 'very potent visuals'. I think everyone is entitled to their own reason to take acid, whether people agree or disagree. I know people who take acid to get fucked up (and that's what they do) and I know people who take acid as an experience in one, both groups sell the same blotter, for the same price and give the same opinions on the blotter, people just have different perspectives. I personally am in the middle, I enjoy acid as it is an amazing experience, you can learn a lot from it and it can really change your perspectives and outputs (although on any psychedelic I've never had any sort of spiritual experience, etc) , but I also enjoy because it's a drug and it gives you some pretty funny giggles and amazing, amazing visuals at times and it gets you pretty messy for 8 hours. - That's what makes it such an amazing substance in my opinion.
Regarding availability I actually haven't really heard much LSD mentioned in a month or so, I am aware that the next batch of Ganeshas where in and is available in sheets. But personally I haven't been looking any myself as I wanted to wait a while before my next trip, also the prices are ridiculously high.
