It's not just age. It's measurable.
Testosterone therapy in the South Bay — properly diagnosed before it is ever prescribed, and monitored by a physician for as long as you're on it. Not a number on a menu.
Most men don't come in. They just adjust.
Testosterone declines gradually from around the mid-thirties, so there is rarely a moment when something is obviously wrong. There is just a slow renegotiation of what a normal day feels like — and a decade later you don't recognize your own baseline.
Flat by two in the afternoon
Not sleepy — flat. The energy that used to carry you to evening stopped showing up.
Training stopped working
Same effort, same diet, less muscle and more around the middle than a decade of evidence says there should be.
A shorter fuse
Irritability, low motivation, or a gray flatness that doesn't rise to the level of anything you'd call depression.
Libido quietly gone
Reduced desire or performance, usually noticed long before it gets mentioned to anyone.
Sleep that doesn't restore
Waking unrefreshed, or a partner who has started mentioning the snoring.
Losing the thread
Words that don't arrive, focus that fragments, the sense of operating a step behind.
Strength slipping
Grip, lifts, and stamina trending the wrong way faster than the calendar explains.
"Everything looks normal"
A physical, a basic panel, and a shrug — without testosterone ever being drawn properly.
None of this is a diagnosis. Sleep apnea, thyroid disease, iron overload, depression, alcohol, and several common prescriptions — statins, opioids, steroids — all produce a version of this list, and some of them are the actual cause of a low testosterone reading. Sorting out which is which is the work.
Everything worth watching shows up in a blood panel first.
Testosterone therapy spent a decade under a cloud that the evidence has since lifted. What remains is not a list of dangers — it is a short list of numbers that move predictably, show themselves on a routine panel months before they would ever be felt, and each have a straightforward answer. That is the entire case for having a physician rather than a subscription.
What the evidence now shows
- The TRAVERSE trial found no increase in major cardiac events — in men who already had cardiovascular risk
- On the strength of it, the FDA removed the cardiovascular language from the boxed warning in early 2025
- In properly diagnosed men it reliably improves energy, mood, sexual function, lean mass and bone density
- Delivery has improved considerably — steadier levels, fewer peaks and troughs, better tolerability
What we track, and what we do about it
- Red cell mass. Rises in some men. We trend hematocrit every panel and treat it with therapeutic phlebotomy here in the clinic, long before it matters
- Blood pressure. Measured at every visit and managed early, alongside the lipids and metabolic markers that actually drive cardiac risk
- Estradiol. Kept in range by adjusting dose and route rather than reflexively blocking it — over-suppression causes more problems than it solves
- Prostate. PSA tracked on schedule, with velocity watched rather than a single number
This is the difference between therapy that works for a decade and therapy that gets abandoned in month four. None of it is exotic. All of it requires somebody to be looking.
Two mornings, and a lot more than testosterone.
A single afternoon testosterone level is the most common way this gets done badly. It is also the cheapest, which is not a coincidence.
- Androgens
- Total and free testosterone drawn between 7 and 10 a.m. on two separate mornings, plus SHBG and DHEA-S
- Pituitary axis
- LH and FSH, with prolactin where indicated — to separate a testicular cause from a pituitary one
- Estradiol
- Sensitive LC-MS/MS assay, not the standard immunoassay, which is unreliable in men
- Blood & prostate
- Complete blood count with hematocrit, and age-appropriate PSA
- Cardiometabolic
- Advanced lipids, fasting insulin, HbA1c, blood pressure, and inflammatory markers
- Thyroid & nutrients
- TSH, free T4 and T3, vitamin D — the common mimics of low testosterone
- Where indicated
- Sleep study, iron studies, and DEXA for body composition and bone density
Panels are tailored to your history and age — this is the shape of a typical baseline, not a fixed menu.
Diagnose, then treat — in that order.
Roughly six weeks from first visit to a settled protocol, then ongoing review for as long as you're with us.
Consultation & History
Symptoms, medications, sleep, family cardiac and prostate history, and whether children are still on the table.
Two Morning Draws
Confirmatory androgen panel plus cardiometabolic, thyroid and prostate markers.
Cause, Then Plan
Dr. Chris identifies why the level is low before recommending what to do about it — sometimes that isn't testosterone.
Monitor & Adjust
Re-test at six weeks, three months, then twice yearly — hematocrit, PSA, estradiol, blood pressure and how you feel.
It arrives in stages, not overnight.
Men who are told to expect everything in week one are the men who quit in month three. This is the pattern we actually see, and it is worth knowing before you start.
- Weeks 2 – 6
- The first things back are usually energy, mood, sleep quality and libido. Most men describe it as the fog lifting rather than a jolt.
- Weeks 6 – 12
- Recovery between workouts improves, mental clarity sharpens, and the irritability that had crept in tends to settle.
- Months 3 – 6
- Visible change in body composition — muscle returning, fat around the middle giving ground — along with measurable strength gains.
- Months 6 – 12
- Bone density gains, better insulin sensitivity, and the point at which most men say they have their baseline back.
- Ongoing
- Twice-yearly panels, dose refinement, and a physician who knows your numbers over years rather than at a single visit.
Therapy amplifies what training and nutrition are already doing — it does not replace them. The men who get the most from it are the ones who use the energy it gives back.
The evaluation exists to get this right.
A small number of conditions mean systemic testosterone isn't the right route — active prostate or male breast cancer, an uncontrolled hematocrit, severe untreated sleep apnea, or uncontrolled heart failure among them. That is what the baseline evaluation is for, and where something needs attention first we will tell you and help you sort it.
And if your testosterone comes back normal, we will say so — then keep looking, because something is producing the symptoms that brought you in. Thyroid, iron, sleep and metabolic health all produce a version of the same picture, and finding the real answer is worth more than a prescription that was never going to work.
Straight answers.
How is low testosterone actually diagnosed?
By two things together, never one alone: consistent symptoms, and low testosterone confirmed on two separate morning blood draws taken between 7 and 10 a.m. Testosterone swings substantially over a day and drops during acute illness, so a single afternoon draw is close to meaningless. We also measure free testosterone and SHBG, because a man carrying extra weight can have a normal total testosterone and a genuinely low free level. Then we look for a cause — sleep apnea, medications, thyroid disease, iron overload and pituitary problems all produce low testosterone, and some of them need treating in their own right rather than being papered over with a prescription.
Isn't testosterone bad for the heart?
That worry dominated the conversation for a decade, and the evidence has since gone the other way. TRAVERSE — a large randomized trial specifically in men with hypogonadism and existing cardiovascular risk, the group you would worry about most — found no increase in major adverse cardiac events. On the strength of it, in early 2025 the FDA removed the cardiovascular language from the boxed warning across every testosterone product. What remains on the monitoring list is straightforward and entirely manageable: testosterone can raise red cell mass and can nudge blood pressure, both of which we track from your first follow-up panel onward and both of which we act on early. That is the whole reason this is done in a clinic.
What if I still want children?
Then we plan for it, and it is very workable. Testosterone from outside the body quiets your own production while you are on it, including sperm production. Most men starting therapy in their forties and fifties have completed their families and this is simply a box to tick. If you have not, or you are unsure, there are three good options and we will walk through them at the first visit: bank sperm beforehand, which is inexpensive and settles the question permanently; run hCG alongside therapy, which keeps your own production going throughout; or, if you change your mind later, use a restart protocol with hCG and clomiphene, which restores sperm production in a large majority of men. The only version of this that causes problems is the one nobody discusses in advance.
What about the testosterone I can get online or from someone at the gym?
You can certainly get it. What you cannot get is the part that makes it work well. The molecule is the cheap component; the diagnosis, the dose that actually suits your physiology, and the quarterly panel that keeps it dialled in are what separate a man who feels transformed at six months from one who feels jittery and gives up at three. Red cell mass, estradiol and blood pressure all shift predictably on therapy, all are visible on a routine panel long before they are symptoms, and all have straightforward answers when someone is looking at the numbers. Unsupervised, nobody is looking.
Injections, gel, or pellets — does it matter?
It matters mostly for how steady your levels are and how well you will stick with it. Small subcutaneous injections once or twice a week give stable levels at low cost, and most men self-administer easily after being shown once. Daily topical gels avoid needles and mimic the natural daily rhythm, but absorption varies and there is a real transfer risk to a partner or child through skin contact. Implanted pellets are placed a few times a year and are excellent for people who travel constantly, at the cost of a minor in-office procedure and less flexibility if a dose needs changing. There are also oral and nasal options. We will recommend based on your levels, your schedule and your preference, not on what is most convenient to dispense.
Once I start, am I on it for life?
That is your decision, reviewed annually, and it depends on why your level was low in the first place. If the driver is sleep apnea, an opioid prescription, excess weight or a thyroid problem, treating the cause can restore your own production and therapy becomes a bridge rather than a destination. If it is primary testicular failure, therapy is usually long-term and men generally stay on it because they like how they feel. Either way you are not locked in: if you want to come off, we taper deliberately and can support the transition with a restart protocol rather than leaving you to fall off a cliff.
