Vyvanse's slow-release mechanism, dependent on red blood cells cleaving lysine, leads to smoother, more evenly distributed entry into the body.

“the one I like the most or for a long acting amphetamine product is viance and viance was designed as a slow release product it was designed specifically to be unattractive to drug abusers so viance chemically links a dexamine molecule to line one of the amino acids it's a basic component of proteins and 20 essential amino acids and if you snort it or inject it you have an inactive prod drug you have the listex amphetamine your red blood cells actually need have an enzyme that Cleaves cine and leaves you with free active dexamphetamine and that's the slow release mechanism is how quickly your red blood cells can do it and they have limited capacity to do that”

“and also towards the end of the day one of the the best in terms of not falling off abruptly um the potential downside is again that the capacity of the red blood cells is limited so at some point for most people because that's a rate limiting step when you're adding more and more you're actually extending the duration of time more than you're getting a bigger Peak because your your red blood cells just aren't cleaving it fast enough to make more Dexter amphetamine available”
