Testosterone therapy and men's health for Cypress. Six miles down Valley View — the full panel, read and tracked.
Castellano Health Institute serves Cypress men a six-mile drive down Valley View — same doctor every visit, a full hormone and metabolic workup instead of a single number, and the trend tracked at every follow-up.
Garden Grove · Mon–Fri 9 AM – 5 PM
The Cypress patient Dr. Castellano sees most.
He works in something measured — engineering, aerospace, a hospital, an analyst’s desk — forty-five to sixty, the kind of man who trusts a number he can see moving over time more than a verdict handed down in a fifteen-minute slot. His annual physical says “normal,” but normal is a single dot on a wide chart, and he knows the difference between one reading and a trend.
What he wants isn’t a bigger promise; it’s a better dataset. Where does his testosterone actually sit against his own baseline — not the population range? Is his free fraction low even though the total looks fine? Is a quiet thyroid shift or a fasting insulin that’s been climbing the thing actually driving the fatigue? Those are questions a full panel answers and a screening tube doesn’t.
One reading is a data point. A trend is the picture.
The weakness of the once-a-year lab isn’t only that it’s narrow — it’s that it’s a snapshot. A single testosterone value sitting inside a reference range that spans healthy twenty-five-year-olds and struggling seventy-year-olds tells you very little on its own. The signal lives in the movement: where the number is now versus where it was, and which direction it’s heading.
That’s the case for a full panel read by the same doctor at every visit. Dr. Castellano runs testosterone with its related markers alongside thyroid, cortisol, and fasting insulin, then reads each follow-up against your own prior set — so a dose adjustment at eight weeks is a response to evidence, not an educated guess. Thirty years of reading these panels is what turns a column of numbers into a direction.
Same doctor, every visit. From Cypress to your follow-up.
The drive from Cypressbuys continuity: one doctor — Dr. Castellano, board-certified in Family Medicine, three decades in — who reads the wider panel himself and tracks it every visit. And when the hormone numbers read borderline while the symptoms don’t, hormone support runs the deeper workup that often surfaces the thyroid or cortisol pattern underneath.
Coming soon.
Dr. Castellano sees Cypress men every week. Their before-and-after stories will land here as patients give consent to share. In the meantime, ask about results in person — bring your most recent labs and we’ll show you how the trend lines look in practice.
The questions Cypress patients ask most before the first visit.
- How far is the clinic from Cypress?
- About six miles — down Valley View or a short run on the 22 to S Euclid. Most Cypress patients are in and out inside 90 minutes, lab draw included. Free on-site parking at the suite.
- What does a full panel actually measure?
- Total and free testosterone with SHBG, a full thyroid, morning cortisol, and fasting insulin with a HOMA-IR — not just a single total-T checked against a wide population range. Dr. Castellano reads those numbers against your symptoms and your own prior baseline, which is where an "in-range" result can still be low for you.
- Do you track results over time or just at the start?
- Every visit. One reading is a data point; a trend is the actual picture. Because you see the same doctor each time, the eight-week and follow-up labs get read against your last set — so a dose gets adjusted on evidence, not a guess.
Six miles down Valley View to S Euclid. Free parking on-site.
Cypress patients start with the same core program every man here does: testosterone replacement therapy with Dr. Castellano — $250 a month, labs and monthly follow-ups included. (The initial consultation and bloodwork before starting are a separate service and cost.)
One conversation tells you whether this is the right fit.
Call the office to set up a 1-hour consult with Dr. Castellano. Bring whatever bloodwork you have on file — or fresh labs get ordered up front. Either way, you’ll leave with a real read on what’s going on.
Calling after hours? Leave a message — we’ll get back to you the next business day.
