Privacy
What we collect, and what we don’t.
Cornerstone Peptide Co. is a B2B supplier. The only personal information we hold is what you choose to send us when you request a quote or subscribe — nothing is gathered in the background.

Who we are
This site is operated by Cornerstone Peptide Co., Wilmington, Delaware. We are the U.S. commercial supply partner for an FDA-inspected peptide manufacturing facility; we are not the manufacturer of record. For any privacy question, write to hello@cornerstonepeptide.com.
What we collect
We collect personal information only when you submit it to us directly. There are two ways that happens:
- Quote and briefing requests. When you ask for pricing or documentation we collect your buyer category, name, company or institution, email, an optional phone number, your state or country, the molecules and volumes you are interested in, and any message you add.
- Newsletter. If you opt in, we keep the email address you give us until you unsubscribe.
We do not run analytics, advertising, or tracking cookies, and we do not follow you across other sites. The site sets only the cookies a page needs to function.
How we use it
We use what you send us to respond to your request, prepare pricing and documentation, qualify buyers during procurement, and — only if you opted in — send the newsletter. We do not use it for automated decision-making or profiling.
Who processes it
We rely on a small number of service providers to run the site and reach you: Vercel hosts the site, and Resend delivers our email. These processors handle your information only to provide their service to us. We do not sell, rent, or trade personal information. During buyer qualification we disclose only what a transaction requires, under mutual confidentiality.
Retention and your choices
We keep quote and qualification records for as long as needed to serve the buyer relationship and meet our legal and recordkeeping obligations, then delete them. You can unsubscribe from the newsletter at any time using the link in any issue, and you can ask us to access, correct, or delete the information we hold about you by emailing hello@cornerstonepeptide.com.
Security and changes
We take reasonable measures to protect the information you send us, though no transmission over the internet is ever perfectly secure. If we change this policy we will update the date above; material changes will be noted on this page.
