Sorry, we don't allow batch and purity discussion in PD. It is impossible for us to say how many batches of LSD blotter there might be that have Rolling Stones prints, I know they have been around for years and it just depends on when people laying the LSD choose to use those blotter prints. The only thing that can say for sure if they do contain LSD and what dosage is lab analysis which is free in a few countries but costs money in most other countries.
Please refer to regional fora (EADD / NSADD) on bluelight to inquire about LSD batches, where it is apparently allowed. PM a mod if you have questions.
