I found this, from an Indian pharmacy I use:
DM Pharma Bridge Export, Nagpur - Trader - Wholesaler / Distributor of Steroids Tablets And Injections
Trader - Wholesaler / Distributor of Steroids Tablets And Injections, Erectile Dysfunction Medicines - 2 & Anti Depression, Anti Anxiety And Other CNS Meds offered by DM Pharma Bridge Export from Nagpur, Maharashtra, India
www.dmonlinemeds.com
They have both ampules and vials of iron. (Personally, I prefer vials for my subq injections, but I have never used iron.)
This vial is for infusion too, but vials are more expensive ($45 in this case):
This ampule for IV infusion is much cheaper ($4):
