What Raises or Lowers SHBG, and What Should You Do About Your Result?

A guide for natural men and men using testosterone or anabolic steroids.

Start with sections 1–4 to understand your result and decide what to check. Use the catalogue when you want the evidence for a particular drug or supplement.

Sections 6–7 answer common questions and explain follow-up. The appendices give the detailed science and further examples.

Interpret SHBG together with free testosterone, symptoms and the medicines or steroids you take. The same SHBG result can mean different things in a healthy man, a man with thyroid disease and a man taking steroids.^[1][2][3]
