IDUN recently had a BOGO deal at which I picked up six 30mg GLP-2 vials. I didn't need a whole kit, just enough to tide me over until I could place a larger internationally-sourced order. My shipment came quickly by 2-day air, the contents were packaged securely, and the vials all had labeling showing product details and batch info. IDUN also enclosed a printout sheet, from Freedom Diagnostics, with the coa and testing report for that batch. I got email updates about order status, shipping status, delivery status, etc. and the vials went out lightening-fast, even though I ordered during a holiday weekend. I'm two bottles in, and all my research results suggest that the product is exactly as advertised, so if you are looking for a quick, domestic and trustworthy vendor, with good sale pricing, IDUN definitely delivers!
