Peptide Sciences shut down: what happened and where to buy instead

peptidesciences.com · Updated 20 October 2026

Peptide Sciences sold research peptides online, from BPC-157 and TB-500 to peptide capsules and blends. By 8 March 2026 its homepage had been replaced by a short notice saying it had decided to voluntarily shut down operations and stop selling its research products.

The notice gave no reason. By September 2026 it also said that any site claiming to be a successor, or claiming to sell its products, is not authorised by the company.

Other sites have offered reasons for the closure; the company has not confirmed any of them.

Timeline

    An archived copy shows the store selling. Its homepage banner names Melanotan II, CJC-1295, GHRP-2, Hexarelin, IGF-1, Sermorelin and TB-500.[1]

  2. 8 March 2026

    An archived copy shows the notice in place of the store: a voluntary shutdown, no reason given, no successor named.[2]

  3. 8 September 2026

    An archived copy shows a longer notice. The company keeps the rights to its name and trademarks, and says any site claiming to be a successor or to sell its products is unauthorised.[3]

What this means for buyers

  • According to the company's own notice, any site that says it is the new Peptide Sciences, or that sells its products, is not authorised. Check the web address before you pay.
  • The company gave no reason for closing. Treat any explanation you read elsewhere as unconfirmed.
  • The prices below come from stores in our index. A price listing is not a test of the product.
