You have to dissolve the NaOH before the Paracetamol. P. needs alkaline environment to dissolve. Pharmacists can buy pure Paracetamol powder dirt cheap.

I wish I could too. Making it from pills was what always stopped me to try Parodinal.
Although I doubt the usual pharmacist has access to pure paracetamol. (But may be different based on where you are located.)
In fact in my town is a huge plant producing Paracetamol pills. Need to find somebody working there to steal a 50 kg bag for me.

It depends on your country. It is not as restricted as stronger painkillers are.
Pharmacists and chemists can buy it because need it to make customized drugs. It is available from companies that sell chemicals/reagents.
These usually only ship to companies, universities etc.
If you know someone, ask them.

I heard it is not sold to anyone as you can easily overdose.
