Great prices, fast shipping, and they even included a print out of the COA for the batch in the package.

Thank you, Angela. We aim to keep it affordable and hassle-free — right down to printing the batch COA so you can compare it to the vial the moment you open the box.
Karyn Allison M.
I did a lot of vetting before deciding to order from Idun and the reviews were right. I ordered Reta from them on SAT and just got my pkg on MON. Recon'd crystal clear. Packaging is flawless in my opinion. COA included; everything matches! I love the font and colors they use. They have an affiliate program you can sign up for that pays 25% commission on all orders. I will be signing up! :))

Fast and courteous service. I am pleased with my peptides also, very clear and pure. They also send a printout of COAs in every order.
