I'm in between gate keeping this company or telling everyone. Been in this research space a while. This company is doing it right. Great customer service, coas, prices. Hope they don't fall into the same greed that all the other small companies I supported that raised their prices ounce they got popular.

* Edit: I really appreciate the reply with positive attitude from IDUN so I edited this review and gave a 5 star rating instead. A company that actually listens to customers and took actions? Amazing! IDUN continues to impress me. I feel they really do go above and beyond for their customers. I will definitely being placing more orders. Hope they'll be carrying even more peps like ghk-Cu/KPV blend. * Original review: After having a good test run experience first time around, I came back and planned to purchase other peps and I was so surprised that the prices were raised drastically across the board. It's incredibly disappointing because I actually spent time writing a glowing review before this. Prices are no longer competitive so there's no reason for me to buy from here again.
Response from IDUN PeptidesAug 18, 2026
We read this, agreed with it, and jumped into action. The Kit Up & Save Summer Sale prices that expired over the weekend are back, permanently. We're small enough that a customer can change our pricing in days instead of quarters, and honest reviews like yours are how that happens. Thanks for telling us straight.

I've emailed them a couple times with questions and their communication is over the top good. The products are great and I love that they reward you with free goodies like BAC water. It's not like I had to spend an exorbitant amount to get these goodies either. Best prices I've seen from a well-respected research peptide provider!
