2.5mg dut daily sources that arent too costly?

Recently bumped up from 0.5mg to 1mg dut dai and after 2 months i can already tell the positive difference. At this point determined and convinced enough to go big and crank it up to the max 2.5mg daily. Im already using multiple scripts and did find a source online. However, crunching the numbers i would spend upwards of $2300 per year to pop 5 of these pills per day, and thats not even including minoxidil and other supplements. 2.5mg daily users…where are you getting yours from??
