I found that a line of mephedrone and bit mixed in water kept me going from about 10 pm until about 3 am without wanting a top-up. I didn’t know the quantites involved though as it came in 5g bag. I think my latest delivery contains individually sealed 1g bags so experiments will be easier to gauge 🙂
I’m pretty sodding impressed by methedrone to be honest. The 20th high had the same impact as the first one whereas my first mdma high was amazing and the rest were just great.
