Chameleon Peptides has closed. As of November 5, 2026, the shop and product pages at chameleonpeptides.com all redirect to a notice headed "Chameleon Peptides is Closed," with a sign-in box for past customers.
The domain was registered on October 8, 2025, and archived copies first show the store live in February 2026, so it traded for about a year at most. Archived product pages name the operator as Origin Sourcing Group LLC, doing business as Chameleon Peptides, in Sacramento, California.
What the notice says
The notice says the company is "now closed for new purchases" and that new account registration is closed. It carries no date and gives no reason, and it does not point to another supplier.
The last archived copy of the working store is from September 20, 2026, and the earliest archived copy of the notice is from October 15. CompoundReview, a review site that says it read the company's emails to customers, dates the announcement to September 27 and a farewell email to October 1. We have not seen those emails.
We found no FDA warning letter or Federal Register notice naming the company or its legal entity, and we are not assigning a cause.
Two practical points follow from the notice:
- Anyone with an open order or a problem with a past one is directed to the support email address printed on it.
- It says past customers can still sign in to see order history and lab reports. Nothing says how long that will last, so anyone who needs a certificate of analysis for a past purchase should save it now.
The similarly named chameleonpeptide.com is still up, as a landing page whose shop links lead to the closed store. We found no other store operating under the name as of November 5.

The store's product sitemap lists 41 compounds and blends, all of them stocked by other vendors in our index:

Copies from May 2026 show the line under earlier names: GLP-1S, GLP-1T, GLP-3 and GLP-1C. It also sold SS-31 as Peptide-31.
