ritalin IR extraction method agreement

[Lehendakari]

Ritalin is loved by many and hated by others. SWIM is a lover and loves to snort it but he realizes the amount of shit he takes throught his nostrils. You have to size the size ofthe pills and the amount of the active component.

There isn't much information about extraction methods, I UTMSE and got some users using alcohol and others doing a symply water-cotton filtered extraction.

SWIM wants to know which of these methods is the best and the answer could be the fillers in ritalin pills. Anyone know them?

Methylphenidate HCL is soluble in water and alcohol so doing double extraction method should not result in methylphenidate loss right??
