Currently you can get the lowest price at Walgreens with a coupon from Goodrx. Cost: $44.38 for a 10mL vial, 200mg/mL. You can either go to GoodRx and print the coupon out - or get an App for your phone and show the coupon on your phone right to the pharmacist!
DO NOT go through your insurance. Pay cash or credit card, or whatever for it.
By the way, if you do SQ, the lowest prices for 29 gauge, 1/2 syringes are Easy Touch at OTCwholesale.
