I've been a lurker on bluelight.ru for a long time, after reading this thread I do however feel the need to interject my own view
I see a lot discussion of purity in this thread and talk about analogues. Personally I don't believe in the whole purity effect, I think most of it can be ascribed to set and setting and expectations. Compounds such as iso-LSD and lumi-LSD have been shown to be not psychoactive at low dosages. The chances of other adulterants being present and being active at such low ranges just don't seem plausible too me especially if you read some of the LSD analysis articles on Erowid. One of the articles reported based on large sample testing in earlier years that for the most part there are no adulterants present. There have however ever been a few exceptions but these are rare occurrences and contained another substance all together. It's also less likely for an adulterant to be present on a blotter as opposed to a microdot for example.
The whole body load difference is another aspect that I read a lot about. One of the things that comes to mind is expectations and set and setting. Also a lot of people report body load based on a selective or single experience. In order for something like this to be attributed to a batch of blotters multiple people would have to be affected with similar body loads and it has to be consistent across multiple sessions of dosing. If you experience a bad body load once or twice using a certain blotter batch I would hardly think this is a basis for attributing it to the LSD, I would be more inclined to look at other factors as the cause. In statistics they have a nice quote that seems to fit this in my opinion "
Correlation does not imply causation". Human nature seems to prefer that correlation does imply causation for the most part hehe
From personal experience I've had aches and pains on occasion using certain blotters, however when dosing a few weeks later using the same batch of blotters I experience a perfectly "clean" trip without this body load. This is in part for me the basis on which I believe that body load is affected by factors other than the LSD.
In regards to the analogues discussion, on another forum I'm on a person contacted the Dutch drug testing service and was provided with results for 2011. Of the 37 samples they received all where tested positive as LSD with the dosage being between 10 and 150 ug on average. They also reported the current LSD market in the Netherlands as being rather stable. In regards to the testing produces the following was reported on Erowid: "The Dutch lab reports that they use HPLC for their quantification and occasionally use GC/MS to verify results." On average it takes between 2-4 weeks for them to process a single blotter and report the microgram dosage.
In summary my believes are LSD = LSD no matter the difference in purity. This statement seems to be in part corroborated by the
lucky few who had the chance to try some original Sandoz LSD that had been stored for years on Hoffman's 100th birthday celebration. I understand that many people don't share my view and that this might be something that'll be discussed for ages too come. It's a shame that proper scientific studies of LSD is almost out of the question in current day and age.
Based on another thread on the forum where people posted print + reported test results I can tell you these 2011 results include the Ganesha/Alex Grey print which was reportedly tested at 50ug (description even matched in regards to taste), some other users reported Avatar prints (only yellow border at the bottom, female) which had been tested at 150ug. In regards to blotters this does not take into account different batches. Unfortunately these are the only two blotters I can report with almost 100% certainty.
The Shiva/Buddha/Buddha Palm blotter exhibits the same taste as the Ganesha/Alex Grey print. This makes me believe they are from the same producer. I've had both prints and the batches I've had of Ganesha and Shiva/Buddha makes me suspect they're 50ug as well even though they're advertised at two different strengths. This is speculation on my part though and based on my subjective experience with multiple trips on both since to my knowledge nobody has posted the test results for the Shiva/Buddha print yet.
