does acid ever go bad?

I am going to buy some acid and i need to know how long it lasts because i want to save it fro a friend and me

put it in the freezer. in 2 weeks acid loses half its potency if not put into storage!

ah cool, thanks man, should be alright if i put in the freezer for a few weeks? cuz my friend is coming day after xmas, i dont plan on buying it til about dec 5th or so cuz im going on vacation

yeah

i had a trip off a girl who comes into my shop. she had been promising me it for months and she said it had been in her flat for 2 years, just lying around.

well i took it one night, well i took half. so 1 and a half hours later im thinking, i feel something but i'm not trippin, so i took the other half.............half an hour later i was absoluteley bolloxed off my head trippin, dancin round the livin room, laughing my head off, so trips last a long time............. but ideally id keep em in the fridge...... that trip i took was a FAT FREDDY
