Research Chemical most like Dextro-amphetamine (Dexedrine/ Vyvanse)

I know this is an old topic, but I don't want to waste server space by starting a nearly identical topic. My question remains the same:

What RC is most like Dextroamphetamine AND can be insufflated without making you want to kill yourself from the pain?

As I mentioned, I tried 4-FA and it certainly had mild stimulant effects like D-Amph, but it also was a tad too serotonin-oriented for my liking AND I couldn't insufflate it because it hurt too much.

Since I take Vyvanse, which can't be insufflated since it is a prodrug to D-Amph which must be converted in the stomach, I often desire to have a quick snort and get a short rush from it like I used to do when I took Adderall (mixed amphetamine salts) and Ritalin. I really like how Vyvanse helps my mental illness symptoms, but sometimes I still just want to have a rush of stimulant pleasure.

So is there any experiences out there with a RC that is more dopamine-centric than 4-FA that also is not too painful to snort. I can actually snort some pretty painful things (for example, I have insufflated 12mg of 2C-I before), but 4-FA is just too much!

Thanks for your valued input.

 

4-FA was a bit underwhelming for me.. i took about 300mg too :/

has a mild "mdma like" sparkle.
