Not sure how often you could do it without building tolerance, I used it maybe twice a week for several months, that definately caused tolerance. None of the 2c's I've had seemed to degrade over the year or so I had them, all were stored in original bag, room temperature. I noticed serious change only in 5meo-dmt, though other tryptamines likely do as well. From everything I've read 2c-anything should be stable almost forever. Different source, though I've heard they get it from the same supplier.
andruejaysin Reviewed by andruejaysin on . 2c-i freshness For some reason my friends and I haven't been getting as many visuals with the same dose of 2c-i that we used to take and do for like 3 nights in a row with visuals. Is there a tolerance build to 2c-i? Or has it been losing it's potency due to being around about a month? I've stored it at room temp in an air tight bag. How long does 2c-i stay fresh for at room temp? Any way to have it last a long time (how long?) without a fridge? Thanks for any help guys. :pimp: Rating: 5
