We are back up and running! Not all products are in stock, but we have limited availability at this time. Don't miss out on the savings! trizepitide at unbeatable prices!
Due to the high volumes of our orders, we are closing down until the beginning of May to restock. We should have all products in back and be ready to go ! These are not the updates I prefer to share, but I want to ensure the family is taken care of and we never hit a place where we oversell on something that we are unable to fulfill on.
That said, we will run a %5 discount when we open back up! Already low prices lower. Who can beat it!? I hope during this time you give it through regarding being on the fence to join our family. We will always provide low cost kits at affordable rates because an $80-90 vial might look good, but experiments in this area require more than one vial, and tend to go on for some time to see the effects take place in the lab setting. The core of why we off Kits! So you can start - extend if needed - experiments. Please feel free to reach out at any time to our email: DomesticPeptideKits@protonmail.com
