Comprehensive hormone panel
Full thyroid (TSH, fT3, fT4, rT3, TPO), sex hormones, adrenal, SHBG, DHEA-S, IGF-1, and more.

03 · Men's Health

Energy, libido, strength — measured and restored.

Men don't need to accept fatigue, low libido, or slow recovery as 'normal.' KAYU runs the labs your primary care didn't, builds the protocol your med spa wouldn't, and monitors it for you.

TRT done right
Proper lab panels, optimal ranges, and aromatase management — not just testosterone replacement.
Performance + recovery
Peptide stacks layered onto hormone optimization for sleep, lean mass, and workout recovery.
Mental clarity
Your cognitive symptoms are often hormonal. Fix the biology, fix the fog.

Our care philosophy

Six promises we refuse to break.

These aren't marketing bullets. They're the operating principles every physician, protocol, and line of code at KAYU is built against.

Physician-owned

KAYU is owned and operated by practicing physicians. The protocol decisions are made by MDs, not growth teams.

Lab-driven protocols

Every protocol starts with 50+ markers. No guesswork. Your biology writes the prescription, not a template.

503A compounding

Our pharmacy partners are FDA-regulated 503A compounding facilities with rigorous quality controls.

Continuous tuning

Your protocol evolves. Quarterly labs, continuous progress tracking, and physician-adjusted dosing — not set-and-forget.

HIPAA end-to-end

Your PHI is encrypted at rest and in transit. Supabase, Daily.co, DoseSpot, Resend — every vendor carries a BAA.

24/7 messaging

Secure in-app chat with your care team. On-call escalation for urgent needs. Real humans, not chatbots.

Your care team

Meet the clinicians on your protocol.

Every KAYU patient is paired with a real clinician — not a call center. Board-certified MDs, DOs, nurse practitioners, and PAs with deep training in hormone optimization, peptides, and longevity.
