I have already posted this in an ADD thread, but this combination is so good (and cheap) that I feel compelled to share it in this thread too:
Mixing
Geranamine, which has primarily CNS NE releasing\reuptaking inhibiting effects with a relatively low PNS profile, with buphedrone which seems to be more of a mild DARI lacking the NE 'push', in a 3:2 ratio (30mg buphedrone : 20mg Geranamine, etc) is WONDERFUL.
It feels very similar to cocaine, but less edgy, and with much less fiending. Also, it seems to last a good deal longer (You get a nice plateau for around an hour).
Geranamine is fucking CHEAP too, I picked up 2 grams(2000mg) from a site I quickly found on google for $5 shipping included... 0_0
This is an excellent way to stretch out the buphedrone, and honestly the high from 50mg buphedrone and ~30mg geranamine is WAY better than the buzz from sniffing 100mg buphedrone by itself...you're not only stretching it out and saving money you're getting a better drug-experience.
Their durations are also both very similar. I took all of my remaining buphedrone and combined it with geranamine in a 3:2 mix, there's really no reason to do it by itself.
EDIT: All doses in this post are for insufflation. I've come to the conclusion that although buphedrone has a nice rush smoked, it's very inefficient and I feel like a good amount is probably wasted because after 10 minutes you just feel slow and stupid. Sniffing it with geranamine produces a nice euphoria with ample stimulation but very little "jitteryness". I'm on a few fat rails right now ^_^
Also, geranamine burns like HELL snorted. It only hurts for 10 seconds tops though, but it is absolutely excruciating. Still a very nice combo though!
