J's getting a bit of Ketamine soon for next weekend and hes tryin to get the powder form. J's about 155 Ib's, 5'8. J's heard that people sometimes take "small doses" thats called "bumps" that is just a quick, subtle, mellow trip. This is what J's lookin for just for a first time, so whats the proper dose J should take in a bump? PS. i heard that 25 mg would be a decent small dose for a bump.....is this true?
