The only acid I've done is Markovich's 160ug tabs, which I've done 3 times. I now have some of Gamma's 100ug tabs and i was wondering how they compare. The reason why is because tests show markovich's tabs to be underdosed, why'll Gamma's tabs are known to be spot on and claimed to be the cleanest acid. I'm going to a concert in a couple days, and i'm thinking of taking two tabs. I was always completely fine on Markovich's tabs, nice visuals, good headspace, altogether a very nice and mellow trip.
Two from GG's is the sweet spot, had some from a pack i got last week. Get comfortable after you drop though, it'll be an awesome ride lmao!
