got the collagen peptides and some BPC-157 capsules from IDUN Peptides about two months ago. shipping to Ohio took four days and everything showed up sealed and labeled clear. the collagen actually dissolves in my coffee without clumping which is the main reason I would order again

So far, I had a great experience with Idun. Great competitive pricing without having to find a coupon. And I like how thorough they are and making sure they’re only signed to research purposes providing up-to-date COA

Nothing is perfect, but your service is about as close as it gets! Thank you for what you do, I will be returning!

Great product! fast shipping. Absolutely loved that the COA is provided with the product when it arrives. Definitely going through IDUN for all future research.

Prices are good! Shipping was fast. Love the extra touch with the stickers and nice box. Pep’s come with COA that was readily verified.
