I like this compound a lot. It's not very visual, but the body high is great and the headspace is easygoing, yet still psychedelic. This compound is somewhat similar to psilocybin mushrooms, but its signature is very unique -- it's the most atypical of the commonly available 4-sub tryptamines. It's quite possible that you'll become extremely horny while under its influence, so make sure that you have a sex partner and/or time alone. Orgasms on this one are even better than on most other psychedelics. On the downside, some tremors and shakiness, particularly on the legs, might become annoying (I actually enjoy that aspect, though) -- this is energetic material. The comeup will almost certainly be quite fast -- fifteen to thirty minutes (at most) -- so keep that in mind. The duration of the experience should be four to five hours (with possibly another hour or two of residual stimulation). (4-HO-DiPT provides a somewhat shorter experience. It's also a little more "aggressive".)
You should do a 1mg allergy test -- put that horrible tasting thing in your mouth and wait for an hour or two. If everything is fine, then take 15mg orally (at once, rather 5mg + 10mg). You should cap it or parachute it... Otherwise, you will hate me forever -- it tastes *that* bad.
For the record, my doses have always been between 15mg and 30mg, with the upper range being my sweet spot.
