There's plenty of supply in India and you can get a tablet for around C$0.25-C$0.90(2.5mg-10mg), depending on what strength you need. I may just bring in like a year of supply when I'm there next or just try shipping it here.
A year of supply would cost me around 95 C$ vs C$ 720+tax from compounding pharmacy here. I don't know why nobody else is trying to sell minoxidil here to meet demand. Patents? Regulations? There are many generic brands selling in India, bringing prices down.
