Product and Research Disclaimers

Not medical advice

Information provided by McCain Longevity is educational. It is not medical advice, diagnosis or treatment, and it does not create a clinician–patient relationship. Consult a qualified healthcare professional before beginning, changing or stopping any protocol, supplement or medication.

No automated medical guidance

This site does not generate individualised medical recommendations. Nothing here should be interpreted as an instruction to take, adjust or discontinue any substance.

Regulatory status of products

Statements about products offered through this site have not been evaluated by the Food and Drug Administration. Products offered are not intended to diagnose, treat, cure or prevent any disease.

Research-use products

Where a product is designated research-use-only, it is not intended for human consumption and is not sold for that purpose. Products carrying this designation display it on the product page, and acknowledgment may be required before purchase.

Individual results

Responses to any protocol vary. No outcome is promised or implied by the presence of a product, protocol or article on this site.

The McCain Standard

What a product must meet before it enters our catalog, and what we owe you once it does, is set out in The McCain Standard. That document governs what we sell and what we say about it. It does not limit or replace anything on this page: the disclaimers here apply in full.

Third-party dispensaries

Supplements and laboratory testing are fulfilled by third parties, including Fullscript. Those services are governed by their own terms and privacy policies. McCain Longevity does not control their pricing, fulfillment or handling of your information.
