So I was just wondering, every time I see pictures of blotters they are square and probably a little smaller than a pinkie fingernail.

But every time I've had tabs they were like a quarter of the ones seen in pictures, same length but rectangular like they took one tab and cut it four ways.
What is the size of a standard tab?

I would say they were just trying to make money and cut one up but I've eaten two and seen it rain in my apartment, so they aren't weak by any means.
Also I hear "real" LSD is hard to come by, but these small potent strips are all I've ever had so it can't be that rare.

Most blotter hits are 1/4 inch by 1/4 inch squares.. A sheet (100 hits) is 2.5 inches by 2.5 inches.

Most blotters are around 7x7mm or something like that.

Does it taste of something? How long does it take to come up? How long does it last? Can you describe the trip?

You can get Ehrlich reagent for reasonably cheap and test to see if its LSD

Here's some info on colorimetric and other tests. There are links there where to buy the colorimetric reagents.

one has to know his source correctly

a good test is to get drops and test one out on the skin , just rub it on your hand , if you trip its lsd , to test drops is resonably much easier

Back in the day when I enjoyed LSD the average size of the blotter tabs was about 6mm x 6mm.The largest (and by far the strongest) tab I ever took was 11mm x 11mm.When we stop to think about this a little this makes the surface area of this monster 121mm squared; comparing this to an average sized blotter ie 36mm squared, it means a increase in surface area by a factor of 3.36 ie almost 3.5 times the size, and assuming the same amount of active ingredient per sheet this means the strength is increased to a similar degree.

Without doing the maths, I wouldnt have credited the difference to be so large when simply 'eyeballing' the blotter size.

I wouldn't suggest rubbing a drop of LSD in your hand to see if it works. I have literally put my hands in solvent containing over a gram of LSD while laying tenpacks (ten sheets per tenpack. 100 hits per sheet), and after the whole gram was laid it felt like maybe I ate a tenstrip (ten hits) or so. It will absorb in your skin, but very poorly (especially if you don't have the softest skin) and if there is only 1-200 mcg per drop, you probably aren't gonna feel it absorb in your hand/skin. You can drop it on your hand if you want, but lick it, or else you'll waste it.

I'm almost positive its LSD, It tasted maybe very slightly bitter; very slightly.

Takes 30-45 minutes to come up and lasts about 8-9 hours from first effects to the last lingering feelings.

It feels like waves of complete understanding of the universe, and telepathy with friends, like I'm swimming in...the knowledge. Deep thoughts.
Visual effects are mild, trails, fractal patterning, breathing walls, oily rainbows soaking out from lights. I can manipulate the visuals easily.
Body load is low, feels like static in the head sometimes.

Comedown is lame, like I still have the waves of knowledge but can't communicate properly without forgetting what I was going to say. Racing thoughts upon trying to sleep.

The source was never a close friend but seemingly trustworthy people lol.
Don't get me wrong I've had bad acid that didn't do much of anything after 7 tabs.

The best ones were blue greatful dead bears, although I never could tell the pictures because they are so small. I'd get maybe like a part of a leg or something.

although all my testing procedures have been followed by another hit from the same batches , i can surely say good lsd can enter your skin easily and make you trip , once i had about a few drops fall on my hand and i did trip although another hit was taken after 3 hours , the effects take place slowly and might be a little less if consumed this way but one can be sure of the fact he is getting pure lsd and not some research chem

a little of it might be wasted if consumed this way but one does trip if it is lsd , just to check the integrity of the product , back in the day i mean my days of madness swim was dropping lsd in eyes , and what not he could think of, it was crazy , swim was crazy

im getting 1cm * 1cm blotters. no image printed, just white blotter. but im sure is not LSD, as it BURNS real bad when taken sublingually ( and even burn the tonge if you rather put it there). trip is almost like LSD but hits faster ( 30 min) and last good 10 hours. psychedelic images are of a very clear images of people and cities and jungle and very wide visions of things happening unlike lsd IME that just gives psychedelic visions of lights and lines and that kind of stuff.

Get Ehrlich reagent

LSD is still very common, but I've only had blotter twice in my life, and one time it was DOB for sure. It isn't too hard to tell psychedelics apart once you get past threshold doses, some people prefer DOB to LSD, I like them both, but they are both completely different IME. I only work with liquid though. What you describe sounds like LSD, but only you can be sure, I'm not in your head

Whatever it was I love it!
