The two names you mentioned in order refer to Dextroamphetamine and Amphetamine. While each side may have been using different forms of Amphetamines in their concoctions during WW2 the Germans were the ones most notorious for having actual Methamphetamine as an ingredient. And the quality/strength was likely way better than what modern Meth is today on the streets...

I've had many experiences with stimulants but thank God I was never foolish enough to do that much at once like this guy smh. That's basically what would happen though especially with one that last as long as Meth does. Longest I was ever in a state similar to the one described in this video was a couple of days from using a Cathinone in excess that lasted no where near as long as Meth thankfully...
