If you are talking blotter thyen my guess would be that 500-600ugs may be the limit, possibly up to a milligram. If you are talking about microdots or some other pill form, the sky's the limit. But you are most likely not going to find any doses that strong, most range in the 50-150ugs average, though this summer has seen some batches that are probably 200-250ugs range.
I actually just read something this morning that said you can put a max of 5mg on an 8mmx8mm blotter. Thats 5000 ug, right? Sounds like a lot. It was on another forum discussing rcs on blotter.
i believe an amazing amount can be laid down on blotter if done carefully (like a milligram = 1000 mcgs) or more. But, it's these new cardstock doses (very thick paper) that could probably hold multiple milligrams. Theory & reality don't intercept here. i haven't seen 1000 mcg paper doses since 1988, i kid you not. i've taken huge doses since then, but it involved eating a lot of paper. The truth is, we cannot tell the amount of the doses we take. Also, the truth is, most of us can get off meaningfully if not profoundly on many, many fewer micrograms than we think. We're so used to hearing the standard "100 mikes" response, we tend not to think. Here's the facts: Take you body weight in kilograms (if you know pounds, divide that number by 2.2). My body weight at around 115 pounds is approx. 52 kilograms. 52 micrograms will make me trip face. Apply this equation to your own body mass to find your number. This is real. In my limited experience, it is the truly rare (psychologically stable) person who is either unusually sensitive or insensitive to the LSD molecule, so i believe this applies for most of us. Why this rant? To help you estimate your dosages after the fact if you want. How hard did you trip? Did it "feel" like 300 mikes? Well, honestly, if that were me, it would probably have only been around 150 mikes. Based on deduction backwards from this premise, i estimate that most of the paper doses this year are in the 25-40 mcg range. i feel something with one and trip lightly/nicely with two and can take it up to a 10-strip or beyond if i'm willing to become catatonically launched/nailed to the ground for about 2-3 hours.

Eons ago there was a company called PharmChem that would do anonymous analysis of street drugs. The first real acid trip I had was on 3 purple microdot that we had tested. Out of three samples submitted the average dose was 170ugs. We also had liquid tested, two strengths, to confirm the dealers claims. One was 100ugs/drop, the other was 150ugs/drop, confirming our sources claims. This was in the mid-late '70's and sadly PharmChem stopped testing street samples around '77-'78, in large part due to DEA pressure. Being lucky enough to have had confirmed doses, I always use it as a guesstimation guide for approximating strength. The Shiva doses that were around shortly at the beginning of summer I would bio-assay at easily 200ugs or a little more. Not an exact science for sure, but gives me some idea of potency. Spicey Cat I'm glad I'm not the only one here to say that most tabs are greatly exaggerated as to strength. I have said it so many times in these forums I sound like a broken record. I think a lot of people assume 250ugs to be a standard dose because that is what Albert did to confirm the effects of LSD. He got his socks knocked off on that dose. Sandoz distributed LSD in 25ug and 100ug doses for clinical use and recommended starting at 25ugs and working up from there. The potency of LSD is very underestimated.
