Hormone therapy FAQ.
Is TRT safe?
When prescribed by a board-certified physician and monitored with regular labs, TRT has a well-established safety profile. KAYU monitors hematocrit, PSA, estradiol, and liver function at every lab draw to ensure you stay in the safe range.
What about bioidentical vs synthetic hormones?
KAYU exclusively uses bioidentical hormones — molecularly identical to what your body produces. Synthetic analogs have different side-effect profiles. Bioidentical hormones are compounded to your exact dose by FDA-regulated 503A pharmacies.
Will I need to be on hormones forever?
It depends on your biology and goals. Some patients use hormone optimization for a defined period (perimenopause transition, post-surgical recovery). Others maintain long-term protocols. Your physician builds the plan around YOUR timeline, not a one-size template.
Do you treat thyroid?
Yes. We run a full thyroid panel (TSH, free T3, free T4, reverse T3, TPO antibodies) — not just TSH. Many patients with 'normal' TSH have suboptimal T3 conversion. We catch what your primary care missed.
