Peptide Sciences Shut Down: Refunds, Store Credit, and Pending Orders

Peptide Sciences announced a voluntary shutdown on March 6, 2026, in a brief notice that gave no reason and no guidance on refunds, store credit, or pending orders. The site, which Grips Intelligence data cited by The Peptide Catalog put at approximately $7.4 million in monthly online sales at the time of closure, now serves the closure notice in place of its storefront.

What Happened to Peptide Sciences?

On March 6, 2026, Peptide Sciences announced a voluntary shutdown on its own site. The notice gave no reason and no customer guidance on refunds or pending orders. As it stands, it states the company decided to voluntarily shut down and discontinue its research products, asserts that the company retains its trademarks and intellectual property, warns that anyone claiming affiliation or successorship is unauthorized, and lists a contact email for reporting such activity.

The scale of what closed is worth stating plainly: Grips Intelligence data cited in The Peptide Catalog's roundup put the store at approximately $7.4 million in monthly online sales at the time of closure, and the roundup describes it as widely considered the largest grey-market peptide vendor in the US. One of the largest storefronts in the category exited with a brief notice.

Can I Get a Refund From Peptide Sciences?

The March 6, 2026 shutdown notice did not announce a refund process, and we located none as of August 24, 2026. Facts only, no legal advice:

• What the notice says: that the company voluntarily shut down and discontinued its research products, and that it retains and will enforce its intellectual-property rights.
• What the notice does not say: anything about refunds, outstanding store credit, or orders that were paid but not shipped.
• Contact: the notice lists a contact email, which is the only channel the page provides.
• Card disputes: standard card-network dispute processes exist independently of any vendor. Eligibility windows and timelines are set by the card issuer, not by the merchant. That is why the absence of vendor guidance does not by itself close off that route.

What About Store Credit and Pending Orders?

The notice gives no guidance on either, and we located no published fulfillment, cancellation, or credit-conversion process as of August 24, 2026. The current page does surface account log-in and account-credit controls, and lists a contact email. This page states what the public record contains and will be updated if the company publishes customer guidance.

Is the Peptide Sciences Website Still Up?

Partly. As of August 24, 2026 peptidesciences.com serves its closure notice in place of the storefront: the voluntary-shutdown statement, an intellectual-property and impersonator warning, a contact email, and residual account log-in and account-credit controls. Per the notice, the sale of its research products is discontinued.
