Methodology and no-sponsor policy

How grades are assigned. Each compound is graded A to E against a fixed scale described in Chapter 4, based on the quality of published evidence in people. A grade describes the evidence, not whether a compound is safe, legal or right for you.

How regulatory statements are sourced. Every statement about FDA is dated and cites its source, FDA’s own pages wherever possible.

What we don’t take. EvidenceLine Research accepts no payment, free product, affiliate commission or sponsorship from any company that makes, compounds or sells peptides. We don’t name, link to or rank sellers in the book.

What we do earn. Income comes from sales of the book and the Live Edition. Some educators who recommend the book earn a commission on Live Edition sales, and they are required to disclose it.

Corrections. If you find an error, email peptidecompanion01@gmail.com. Confirmed corrections are listed in the public Update Log with the date.
