acid is generally fairly weak these days – go with Daft’s suggestion and do half…you should feel something although potentially not much, unless you’re lucky and get a decent batch. Just take it in stages…there’s no rush. Leave plenty of time between trips too to allow your tolerance to reduce.
If it’s genuine acid it won’t do you any physical harm whatsoever. Psychological harm is possible but very rare. The chances are next to zero if you follow some basic rules – do some reading about set & setting. Some people are predisposed to psychological illness and acid can act as a catalyst but this is also very rare…and I guess is the risk we take!
