If you are trying to get a refund from Peptide Sciences, here is the honest answer up front. The company shut down permanently in March 2026 and did not announce any refund process. There is no checkout, no support line, and no official way to request your money back. That is hard to hear if you have an order or store credit stuck in limbo, so here is what you can actually do about it.
Why there is no official refund
Peptide Sciences closed for good. When it shut down, it did not set up a process to return money on open orders or unused credit, and the parts of the business that would handle a refund, the support team and the checkout, went away with it. So waiting for the company to make it right is not realistic. The company is gone.
What you can actually try
You are not necessarily out of options, depending on how you paid.
- If you paid by credit or debit card recently, contact your card issuer and ask about a dispute or chargeback. Card networks have time limits, so the sooner you ask, the better. This is not guaranteed, but it is the most common way people recover money from a vendor that disappeared.
- Gather your records first. Order confirmation, payment receipt, the date, and any screenshots showing the store is closed. A dispute goes more smoothly with documentation.
- If you paid by a method with no buyer protection, such as crypto or a bank transfer, recovery is much less likely. That is worth knowing honestly rather than chasing a dead end.
None of this is legal or financial advice. It is the practical path most people take, and your bank is the right place to start.
How to avoid being here again
The reason this hurt so many researchers is the prepay model. You send money to a website and trust it will still be there to deliver. When it is not, there is nothing to walk into and no one to call.
The way to remove that risk is to buy from a vendor you can pay in person. Peptide Hackers carries the same compounds Peptide Sciences was known for, with a per batch Certificate of Analysis on every order, and runs two physical storefronts in Los Angeles and Newport Beach. You can pick up the same day in person, see the product, and pay at the counter, so there is no prepaying into a void.
