Lsd is a molecule, if you have 100ug if acid, then you have 100ug if acid.

There is occasionally a difference in the purity of the crystals that the tabs were laid with, but as long as you have lsd and no other active compounds within the crystal it will feel like lsd,

The worries are if people lie about what’s on the tab, eatther sayin that there is more than there is, or saying it’s lsd when it is actually a completely different substance, such as 25i-nbome, or 2C-B etc.

When people say the tabs are bad, it’s usually because they are weak, or not actual lsd,

Some people do believe there are good or bad tabs and that they affect the trip, but it’s usually all in their heads!
