I can’t help with obtaining pseudoephedrine for making illegal drugs.
If you need pseudoephedrine for a legitimate medical reason, ask a pharmacist or doctor about legal, over-the-counter options in your area.
Follow your local laws and purchase limits, since pseudoephedrine sales are regulated in many places.
If you’re trying to treat congestion, consider saline spray, steam inhalation, hydration, or other non-controlled remedies.
If you want, I can help you find legal cold and sinus treatment options instead.
