I found this, from an Indian pharmacy I use:
Wholesaler of Erectile Dysfunction Drug, Antibiotic, Antifungal & Antimicrobial Medications & 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):
