Privacy policy.

Short version: we collect very little, we do not sell anything about you, and we never see your payment details because we never process a payment.

Analytics

We use Google Analytics to understand which pages and compounds people find useful. This collects standard web analytics data — pages viewed, approximate location, device and browser, and referral source. We also record when an outbound link to ZestyRat Research is clicked, and which compound it was for, so we can tell which listings are worth maintaining.

Referral tracking

Links to ZestyRat Research carry campaign parameters identifying this site as the referrer. These identify the site, not you.

Contact form

If you send us a message, we receive the name, email and message you provide, and use them only to reply. We do not add you to a mailing list from a contact form.

What we never have

We never receive your payment details, shipping address or order contents. Those go directly to ZestyRat Research and are governed by their privacy policy.

Local storage

This site stores a small record in your own browser of which product links you have opened, so the page can show you a count. It stays on your device and is never transmitted to us.

Your choices

You can block analytics with any standard browser setting or extension; the site works fine without it. To ask what we hold about you or to have it removed, use the contact form.

How we review suppliers

Fresno Peptide Lab is an independent research library. We do not manufacture, stock, price, test or ship anything. We review suppliers on their published testing standards, reputation, fulfilment record and pricing, and the ratings we publish are our own editorial assessment.

Every compound referenced on this site is sold by its vendor strictly as a research chemical for in-vitro laboratory research only — not for human or animal consumption, and not intended to diagnose, treat, cure or prevent any disease. Nothing here is medical advice. We earn a commission on orders placed through our links, at no additional cost to you; all material connections are disclosed in line with FTC guidelines.
