Dexedrine vs. Vyvanse dosage

[mtu mwendawazimu]

Would I need to take 7 10mg Dexedrine to mimic the effect of 1 70mg Vyvanse, or is Dexedrine a more pure substance?

Dexedrine is stronger. Not sure of the exact conversion, but I think a 70mg Vyvanse is roughly equivalent to 30mg adderall or 20mg dexedrine.

Great - exactly the answer I'm looking for. Thank you!

Any more dosage comparison guesstimations would be greatly appreciated!
