I agree LSA-containing seeds/extract are more challenging body-wise, or can be.
But . . .
If you have fresh seeds (hand pick Morning Glory, if you can’t get fresh hbwr), the experience can be as “clean” feeling as LSD.
I have tripped on lsa and lsd well into the hundreds of times, and do value both.
As said already, there are some differences, albeit subtle to me.
I tend to get more natural themes like plants and vines mixed into a fractal overlay.
LSD gives me a more hyper-real HD technological vibe.
But most of that is largely due to my own experiences, background and suggestion.
To say the compound(s) should be avoided has merit; many find the bodyload huge and uncomfortable.
But . . .
I get huge body loads from eth-lad or 1p-lsd or lsd sometimes, too.
And sometimes from seeds.
I would suggest you find a fresh bunch of seeds and give it a try, starting small of course.
Crushing and soaking in distilled water works well. Look up various teks and try one.
Much better than just mow’ing down on handfulls of husky seeds!
Lastly, and this was touched upon above, there may be internally within you (certainly within me) that natural sources, taken in nature have something special in the peace of knowing this is just as it evolved - no synth, no purification, just grew. And our metabolism breaks down/converts/distributes the stuff we seek for us, no tek required.
And like Peyote, I read (can’t source at the moment) that these seeds contain other compounds, not just lysergic acid amides, which may contribute to the effects.
I still like it, and just last fall did a few MG trips. The year before that a couple HBWR trips. Throughout, I have enjoyed, and had challenges with various RC lysergamides.
So, if you like acid already, try it and you’ll know.
But don’t judge until you’ve tried some fresh seeds, still kinda soft. They get less visual and more crampy as they age (theory).
Good luck!
