What Katalys does
Hormone optimization, held to a clinical standard
Guideline-anchored
Every recommendation is tied to Endocrine Society and major-society guidance — the standards an endocrinologist actually follows.
Reads your panel in context
Interprets testosterone, SHBG, estradiol and thyroid against your symptoms and goals — not a single value in isolation.
Honest about thresholds
Tells you when a repeat draw, LH or prolactin is needed before any intervention — with the evidence grade attached.
A graded answer
It knows when to slow down
Katalys flags what needs confirming before treatment and explains the guideline behind every step — so optimization stays evidence-based, not aggressive.

Katalys Graded answer
A free testosterone of 6.1 ng/dL is below the male reference range of 9–30 ng/dL. Per Endocrine Society guidance, confirm with a repeat morning draw including LH and prolactin before considering any intervention. Verified — High
Elevated SHBG is lowering your free fraction despite near-normal total T Verified — Moderate
TRT is not first-line until secondary causes are ruled out Verified — High
