There is no code because there is no store. peptidesciences.com serves a voluntary-shutdown notice in place of its catalog — verified on the company's own domain. Every "Peptide Sciences code" a coupon site shows you is dead, or belongs to someone using the name.
Affiliate code — confirmed 6 September 2026; we earn a commission on orders that use it. It does not change any score on this site.
What happened
The shutdown notice states the company decided to voluntarily shut down operations and discontinue the sale of its research products, and that it retains its trademarks and will continue to enforce them. It is undated; industry reports place it in early March 2026 without a primary source, so we do not print a date. The closures hub has the full record alongside Science.bio, Paradigm, Chameleon and Chemyo, and the successor-scam pattern that follows every closure: a new domain using the old name, a "discount code", and a payment rail you cannot dispute.
Questions
No. Peptide Sciences has closed — its website serves a shutdown notice stating the company decided to voluntarily shut down operations and discontinue the sale of its research products. There is no cart for a code to apply to. Any 'Peptide Sciences code' on a coupon site is either stale or attached to a site using the name.
The notice on its own domain is undated. Several industry sites report early March 2026, but none cites a primary source, so we do not print a date. The closures hub carries what the company itself said.
Almost certainly not. The shutdown notice says the company retains its trademarks and will enforce them, which is the language a closing company uses when it expects copycats. A domain that is not peptidesciences.com using the name and a coupon is the successor-scam pattern we describe on the closures hub. Do not pay it.
