Medical disclaimer

Everything on this site is general information for education. It is not medical advice, a diagnosis, or a treatment recommendation, and it cannot take your health, history, or medicines into account. Reading this site or writing to us does not create a clinician–patient relationship, and we do not answer personal medical questions.

We do not give doses, schedules, cycles, protocols, or instructions for preparing or administering any peptide, drug, or research material. When a finished cosmetic or supplement states an amount on its label, we may report what the label says. That describes the label; it is not a recommendation.

Materials sold for research use are not intended for people to take, and nothing on this site suggests otherwise. A product listing, a certificate of analysis, or a research-use label does not establish that a product is suitable for personal use. Findings from cell or animal studies do not show that something works, or is safe, in people.

Our guides about prescription and compounded treatments explain terms, evidence, and regulatory status as of the date shown on the page. They do not replace a product’s official labeling or a conversation with the clinician who prescribes it. Regulatory status can change, so check the date and the source. See Approved, Compounded, and Unapproved: Understanding the Terms.

An evidence rating describes how much research supports one claim, for one product form. It is not a safety rating, and it is not a recommendation to use anything. Our methodology explains the scale.

Before you start, stop, or change any treatment or supplement — or if you have questions about a product you already use — talk to a licensed clinician or pharmacist who knows your health history. Do not delay seeking care, or disregard professional advice, because of something you read here.
