I took the whole thing over the course of the day and it felt like acid (always a chance it could be fake, but pretty reliable source), done it a few times many years ago, but it's like it never got going. Had a big body buzz, but there was no trip and almost no psychedelic effect aside from a bit of colour appreciation. Had a positive effect on my headache, but it must be dampened by my meds. Very disappointed lol.
There's some other tabs around soon, I will try those too. Didn't do any harm, was a very nice buzz, but maybe these are weak or something.
