Okay I'm aware of all the points made here. I'm going to be careful guys don't worry about me! And I am sure that I won't have to go to a psych ward because of acid.
Now since that's out of the way can anyone answer my question? There has to be a range of dosage where researchers or users said "okay we need to stop here, this happens around this dose in most people and its bad." Or something similar. You get my point right? Even something like more muscle tension, nausea, gastrointestinal disturbances, or vasoconstriction.
Or is LSD just THAT safe?
Your asking an impossible question there is no way to say at 100mcg you will not have side effects and at 1000mcg negative side effects will develop.
Honestly I would say just google what a thumbprint is and you will see how broad this dosage can be...(I am not saying try a tp)
Just be careful and know your substance, this is why alot of people will eat 1 or 2 off a batch before going for 5-10.
I have eaten 10 strips of fluff and been just fine and had life changing breakthroughs that felt like pure magic. However a couple years back I received some tabs that where laid by a very famous group of people. I started with a half a tab to see what I was dealing with and I had very stong visuals, then a week later I dropped 2 and had an awesome experience , about a month later I dropped 3 and lost my shit completely. It was harder than any DMT breakthrough I have ever had and dont even think I could reach that point without ayahuasca now, it was one of the most frightening bad trips I ever had I took a loooong break after that, I just remember pulling rainbows out of my head, it was a very meaningful trip still no matter how bad it was I learned true respect for this substance ( thanks kesey

RIP )
Make sure to not have anything else in your system and just some benzos near by when hitting these marks try to refrain from taking them to get the full experience, I would say hide the anti psychotics from yourself they do have physical side effects like tremors that would suck if your having a bad time.
The only thing you have to ask yourself is if it is worth it, if you are doing it for the right reasons, what you want to gain and especially if you have the mental capacity to do so.
If your worried about muscle tension stretch before hand.
LSD is not too nausiating and it does tie in with the experience trip on a light stomach.
gastrointestinal disturbances __ hard to avoid with anything
Vasoconstriciton----> What are other opinions on this? I dont worry about it...
LSD is just that safe if you have real LSD-25, A sober friend, proper set and setting and you are in good health overall.
I think your focusing on the physical side effects too much, I would say worry about preparing your mind with meditation.
Its not a marathon you need to prepare for, just know your facts and settle down your mind if this is the experience you want.
I have seen people lit for 2 days off of five fluff tabs (95mcg) they look like they saw some shit! I wonder what I look like after ten lol!
