Periactin?

Hey all.

I've read Periactin (the anti-histamine) is a great appetite stimulant. However, in the US it requires a prescription. In Canada it's over-the-counter (have also had this verified just recently on another board). I've tried to find it to purchase without a prescription via Online Canadian Pharmacies but to no avail.

Does anybody know a way I can get Periactin without a prescription?

Thanks!
