How we keep our health guides honest and up to date
Every guide in Aayu Well's Learn section is reviewed by a physician before it is published and on a fixed schedule after that. Each guide lists its sources, grades the evidence for any treatment it discusses, and shows the date it was last reviewed. We correct errors as soon as we confirm them and note the change on the page.

Written for you, checked by a physician
Every guide is reviewed by Darshan Patel, MD, an obesity medicine physician. The reviewer checks each medical statement against its sources and checks that the page does not promise results. The reviewer's name and the review date appear at the top of every guide.
How we grade evidence
When a guide discusses a treatment, it gives the evidence a grade for the use people are asking about:
- A. Several large randomized trials in people agree.
- B. At least one well-run randomized trial in people, or several smaller ones that agree.
- C. Human evidence is limited to small, short or uncontrolled studies.
- D. Mostly animal or lab studies; human studies are absent or come from a single research group.
Guides that explain rules or processes, rather than a treatment, are marked "not applicable."
The sources we use
In order of preference: FDA labels and federal agency documents; peer-reviewed studies in people, with randomized trials ahead of observational studies; and guidelines from medical societies and the US Preventive Services Task Force. We cite animal and lab studies only to explain why something is being studied, and we label them as such. We link to the original source whenever we can.
What you won't find here
- Doses, or instructions for preparing or mixing a drug.
- Promises of results, before-and-after claims, or practice results we can't document.
- Prices on education pages.
- Any suggestion that a compounded drug is approved, generic or the same as a brand-name medicine.
How often we update
- Peptide pages and our legal status page: at least monthly, and as soon as we can after a rule changes.
- Other guides: at least every six months.
- Every guide shows when it was last reviewed and when the next review is due.
