A patient who decides to explore hormone therapy usually starts with a simple question: which hormone? The next question, which is often asked later and with less preparation, is how. Hormones can be delivered through the skin, under the skin, into a muscle, through the mouth or through the lining of the nose and cheek. Each route gets the same molecule into the bloodstream, but the pattern is different, and the pattern shapes how the patient feels, how often the dose needs adjusting and how closely the treatment needs to be monitored.
Most online comparisons are written as sales pages for one method. This guide is organized differently. It follows the properties that actually matter to a patient: how steady the levels are, how adjustable the dose is, how reversible the treatment is, what the side effect profile looks like and what evidence supports each approach. It also covers the regulatory difference between FDA approved products and compounded preparations, which is a point of real confusion. The content is general education based on published guidance and on how Ageless Health Institute describes its hormone therapy program, and it is not a substitute for an individual evaluation.
Start with the goal, not the method
Delivery method is a secondary decision. The primary decision is whether hormone therapy is appropriate, which hormones are involved and what the target is.
A woman in perimenopause with night sweats and sleep disruption has different needs from a woman five years past menopause with bone density concerns, and both differ from a man in his forties with low testosterone and fatigue. Thyroid, cortisol, insulin and nutrition status can all change the picture. Diet, sleep and stress can drive symptoms that look like hormone deficiency, which is why nutrition and hormones are best looked at together and addressed alongside any prescription.
That is why a sound hormone therapy program begins with symptoms, history and lab work, then moves to a personalized plan. Delivery method then becomes a practical question: which route fits this hormone, this person and this lifestyle?
The common routes
Hormones reach the body in several ways. The main ones are transdermal products applied to the skin, pellets implanted under the skin, injections, oral tablets or capsules, and, less often, vaginal, nasal and sublingual forms. The sections below take them one at a time.
Creams, gels and patches: the transdermal group
Transdermal products deliver hormone through the skin. Patches stay in place for several days and release a steady amount. Gels and sprays are applied daily to a set area. Creams, often compounded, are applied once or twice a day.
Strengths. Transdermal estradiol bypasses the first pass through the liver, which matters because oral estrogen raises certain clotting factors and triglycerides. Observational data and guideline reviews have generally found lower clot risk with transdermal estradiol than with oral estrogen at comparable doses. Dosing is flexible, since the patient can change the amount, and stopping is easy because the effect fades within days.
Limits. Absorption varies. Skin thickness, application site, sweating, bathing and the product’s vehicle all change how much enters the blood. Patches can irritate skin or peel in the Arizona heat and during swimming. Creams carry a transfer risk: testosterone or estrogen gel can reach a partner, a child or a pet through contact with the application site, so covering the area and washing hands matter. Daily application also requires routine, and patients who skip doses see their levels bounce.
Regulatory note. FDA approved patches and gels exist for estradiol and for testosterone in specific indications. Many creams, however, are compounded, and compounded products are not FDA approved. They are not evaluated for safety, effectiveness or quality in the way approved products are, and dosing consistency can vary between pharmacies.
Pellets: the long-acting implant
Pellets are small, rice-sized cylinders of hormone, usually estradiol or testosterone, placed under the skin of the hip or buttock during a brief in-office procedure under local anesthetic. They dissolve slowly and release hormone over about three to six months, depending on the dose and the patient.
Strengths. The appeal is convenience. After placement, there are no daily applications, no weekly injections and no pills to remember. Many patients value the steady-feeling release and the low maintenance. Adherence is easy because the dose is delivered whether the patient remembers or not.
Limits. The same feature that makes pellets convenient makes them hard to adjust. Once placed, the dose cannot be reduced, and removal requires a minor procedure. If the dose is too high, symptoms can last for weeks or months. Blood levels can peak early and then decline, so some patients experience a strong first month and a fading last month. Procedure-related risks include bruising, infection, extrusion of a pellet and scarring at the site.
Evidence and regulation. The evidence for pellets is thinner than for transdermal estradiol or injectable testosterone. Most studies are small or observational, and long-term safety data on compounded pellets are limited. An FDA approved testosterone pellet exists for men, but compounded estradiol and combination pellets are not FDA approved. Professional menopause and endocrine societies generally describe the evidence for compounded pellets as insufficient to endorse them as a first choice, and recommend that patients be told so plainly. A clinic that offers pellets should discuss this openly and should monitor levels, not assume the dose.
Injections: predictable and adjustable
Testosterone is commonly given as an intramuscular or subcutaneous injection every one to two weeks. Estradiol injections exist but are less common. Some practices use smaller, more frequent subcutaneous doses to reduce swings.
Strengths. Injections are inexpensive relative to some alternatives, well studied and highly adjustable. Dosing changes can be made at the next injection, and blood levels follow a predictable curve. For testosterone, injectable forms have decades of clinical data, and several are FDA approved.
Limits. Levels rise soon after an injection and fall before the next one, so mood, energy and libido can swing across the cycle in some patients. More frequent small doses reduce this but add a routine. Patients who dislike needles may prefer other routes, though many learn to self-inject at home. Injection-site soreness, pain and, rarely, abscess can occur. Testosterone can raise red blood cell count, so periodic blood work is part of safe care.
Oral tablets and capsules
Oral hormones are the most familiar route. Oral estradiol, progesterone capsules and conjugated estrogens have long histories, and several FDA approved products exist.
Strengths. Pills are simple, widely covered by insurance and well studied. For progesterone in particular, oral micronized progesterone taken at bedtime is popular because it can aid sleep, and it is used to protect the uterine lining in women who take estrogen and still have a uterus.
Limits. Oral estrogen is processed by the liver first. That increases clotting factors, raises triglycerides and affects binding proteins, which can change how much active hormone circulates. This is the reason many guidelines favor transdermal estradiol for patients with higher clot risk, obesity or migraines with aura. Oral testosterone is a special case: most oral forms are poorly absorbed or can affect the liver, and only select products are approved for use.
Vaginal and local forms
Low-dose vaginal estrogen, delivered by cream, tablet or ring, treats genitourinary symptoms such as dryness, discomfort and urinary urgency. Absorption into the bloodstream is minimal at standard doses, so the risk profile differs from systemic therapy, and many women who cannot use systemic estrogen can still use it. This is a good example of how the right route depends on the symptom: a local problem sometimes deserves a local treatment.
Sublingual, buccal and nasal options
Troches placed in the cheek, sublingual drops and nasal testosterone gel offer alternative paths. They avoid some liver effects, but absorption varies with saliva, food and technique, and several products are compounded. Evidence is limited. They are best viewed as niche options when other routes are unsuitable.
Comparing the routes on what matters
A patient can compare methods on six questions.
How steady are the levels? Patches and daily gels give relatively flat levels. Pellets can feel steady for a while and then taper. Injections follow a peak and trough. Oral products depend on the schedule and on the liver.
How adjustable is the dose? Creams, gels and injections are easy to change. Pellets are hard to change once placed. Oral doses are adjustable but limited by tablet strengths.
How reversible is it? Daily and weekly methods stop working within days of stopping. Pellets keep releasing for months.
What are the safety trade-offs? Oral estrogen has a higher clot signal than transdermal estradiol. Testosterone, in any form, can raise hematocrit. Compounded products have less consistent quality oversight.
How strong is the evidence? FDA approved patches, gels, pills and injectables have the strongest data. Compounded creams and pellets have the least.
How much effort does it take? Pellets require the fewest actions over time. Creams and pills require daily effort. Injections require a weekly or biweekly routine.
No method wins every row, which is why a conversation about priorities matters.
Matching the method to the person
Examples help, with the caveat that these are illustrations and not prescriptions.
A woman in her early fifties with hot flashes, a uterus and a history of migraines with aura might be steered toward transdermal estradiol plus oral micronized progesterone, because the route lowers clot risk and the progesterone protects the lining.
A woman with only vaginal dryness and painful intercourse might do well with a low-dose vaginal estrogen, avoiding systemic therapy altogether.
A man in his forties with confirmed low testosterone and symptoms might choose weekly or biweekly injections for predictable dosing and monitoring, or a daily gel if he prefers to avoid needles and is careful about transfer.
A patient who travels frequently and finds daily routines hard might consider pellets after a frank discussion of adjustability, evidence and removal.
A patient with a history of blood clots, active breast or prostate cancer, unexplained vaginal bleeding or severe liver disease may not be a candidate for systemic hormone therapy at all, which is why history comes before method.
Monitoring: the step that matters for every route
Whatever the route, safe hormone therapy involves follow-up. Baseline labs establish a starting point. Repeat labs after a few weeks to months confirm that levels are in the intended range, and symptoms are tracked alongside numbers. Patients on testosterone typically have hematocrit, PSA when age-appropriate and lipids checked periodically. Patients on estrogen are screened for breast health and, if they have a uterus, for bleeding patterns.
Two cautions apply. First, symptoms and numbers do not always agree, and treating the number alone can mislead. Second, the timing of a blood draw matters: a level drawn at the peak of an injection or the trough differs from the average, so interpretation needs context.
Insulin resistance, weight, sleep and stress also modify how patients feel on any hormone plan. Patients who address insulin resistance and sleep quality often find they need a lower hormone dose and feel better on it.
Hormones and weight: a realistic expectation
Many patients ask whether hormone therapy will help with weight. The honest answer is that it can help indirectly, through energy, sleep, mood and muscle maintenance, but it is not a weight loss drug. The relationship between hormones and weight is more nuanced than most marketing suggests, and delivery method does not change the fundamental answer. Patients who want body composition change typically pair hormone care with nutrition, strength training and, where appropriate, medical weight loss support.
Cost and insurance: things to ask
The practice does not publish a hormone therapy price in this guide, and costs differ by method. Questions worth asking include what the initial visit and labs cover, whether follow-up labs are included, how often visits are needed and what a dose change costs. Pellets typically involve a procedure fee at each placement, while creams, injections and pills involve recurring supply costs. FDA approved products may be covered by insurance in some cases, whereas compounded preparations and pellets are often paid out of pocket. A written estimate for six to twelve months allows a fair comparison.
Red flags in a hormone clinic
Several signs suggest a patient should slow down. A one-size-fits-all protocol that begins before labs are drawn. A guarantee of specific results. Claims that compounded products are safer or better than approved ones. Pressure to sign up for a prepaid package at the first visit. A refusal to discuss risks or alternatives. No plan for follow-up labs. Any of these deserves a second opinion.
Perimenopause, menopause and the case for starting low
Women in perimenopause present a particular challenge for delivery choice, because hormone levels do not fall in a straight line. Estradiol can swing from very high to very low within weeks, cycles become irregular and symptoms such as night sweats, anxiety, joint aches and sleep fragmentation come and go. A method that delivers a fixed, steady amount, such as a patch, can feel stabilizing in that setting, and some patients find that a lower dose than expected is enough. Pellets, which cannot be reduced once placed, are harder to match to a fluctuating baseline.
Timing matters as well. Guideline groups generally describe the most favorable balance of benefit and risk for systemic hormone therapy in women who start within roughly ten years of menopause or before age sixty, with symptoms such as hot flashes as the main indication. Starting later, or starting for prevention of chronic disease alone, calls for a more cautious conversation. The practice’s approach of beginning with history and labs fits that logic, because the answer to “whether” shapes the answer to “how.”
Progesterone deserves its own sentence. A woman with a uterus who takes estrogen needs a progestogen to protect the uterine lining, and the route matters. Oral micronized progesterone at night is common, and it often improves sleep. Creams are sometimes used for this purpose, but absorption through the skin is unreliable and the evidence that they protect the lining is weak, so a clinician should confirm protection by a method with better support.
Men, testosterone and the questions that come before the prescription
For men, the delivery decision follows a diagnosis. Low testosterone is confirmed by symptoms plus repeated morning blood tests, and the cause is explored: sleep apnea, obesity, medications, diabetes and chronic illness can all lower levels. Testosterone therapy can suppress sperm production, so a man who wants to father children needs a different plan, and every delivery method shares that effect. Injections and pellets raise levels more reliably than gels, and gels are more affected by skin and application technique.
The practical considerations are modest but real. A man who travels, dislikes needles or works in conditions where gel transfer could be an issue will weigh the routes differently from a man who is comfortable with a weekly injection. Hematocrit needs checking, and blood pressure, sleep apnea and prostate health are part of the follow-up. A clinic that discusses the prescription without these checks is not offering complete care.
What a good follow-up visit looks like
The first prescription is a draft. A good follow-up visit reviews symptoms in plain language: sleep, energy, mood, hot flashes, libido, exercise recovery. It reviews labs in context, notes the timing of the draw relative to the last dose, and asks about side effects such as acne, breast tenderness, bloating, mood swings or irritability. The provider then adjusts one variable at a time, so the cause of any change is clear. Switching the route, the dose and the schedule in the same visit makes it impossible to tell what worked.
Patients can help by keeping a short log for the first two or three months, noting dose timing and symptoms. That record often settles questions that lab numbers cannot.
Questions worth asking at the first visit
- Which hormone, and why, based on my symptoms and labs?
- Which delivery methods fit my history, and which do you advise against?
- Is the product FDA approved or compounded, and what is the difference for me?
- How will the dose be adjusted, and how quickly can it be changed?
- What labs will be monitored, and when?
- What are the signs that I should stop or call?
- How does the plan fit with nutrition, sleep, stress and weight?
- What does a six month estimate look like?
Patients who want to talk through these questions can request a consultation with the team at Ageless Health Institute, where hormone care sits alongside functional medicine services.
Stress, cortisol and the hormones that are not prescribed
A final point concerns the hormones that do not come in a pellet or patch. Cortisol, insulin and thyroid hormones interact with sex hormones. A patient who is chronically stressed or sleeping poorly can have symptoms that resemble menopause or low testosterone, and giving more sex hormone may not fix them. Chronic stress changes the picture too, since cortisol and weight are tightly linked and the same stress physiology affects the outcomes patients hope hormones will change. A thorough workup looks at the whole system, then picks the route.
The takeaway
Delivery method changes how steady the levels are, how easily the dose can be changed, how reversible the treatment is and how much evidence supports the approach. Patches, gels, injections and pills have the strongest track records, and transdermal estradiol has a favorable clot profile compared with oral estrogen. Pellets are convenient but less adjustable and less studied, and compounded preparations lack the oversight of approved products. The best choice depends on the hormone, the symptoms, the medical history and the patient’s tolerance for routine. A careful clinic starts with the question of whether and why, and treats the method as a decision to revisit as needs change.
Frequently Asked Questions
What is the best way to take hormone therapy?
No single route is best for everyone. Transdermal estradiol has a favorable clotting profile, injections are predictable and adjustable for testosterone, and pellets are convenient but harder to adjust. The right choice depends on the hormone, medical history, goals and preference.
Are hormone pellets safe?
Pellets are used widely, but evidence is more limited than for patches, gels and injections. Compounded pellets are not FDA approved. Risks include procedure-related infection or extrusion, and doses cannot be reduced once placed, so monitoring and an open discussion of alternatives matter.
How long do hormone pellets last?
Pellets typically release hormone over about three to six months, depending on the dose and the individual. Some patients feel the effect fade before the next placement, which is one reason follow-up labs and symptom tracking are important.
Are creams or injections better for testosterone?
Injections give predictable dosing with peaks and troughs, while gels give daily, flatter levels but carry a transfer risk to others. Both can be effective. Choice depends on needle tolerance, routine, cost and how levels respond.
Is transdermal estrogen safer than oral estrogen?
Guideline reviews generally find lower clot risk with transdermal estradiol than with oral estrogen at comparable doses, because the transdermal route avoids first pass liver processing. Individual risk still depends on age, history and other conditions.
What does compounded mean for hormone therapy?
Compounded hormones are prepared by a pharmacy to a prescriber’s specifications and are not FDA approved. Approved products undergo review for safety, effectiveness and manufacturing quality. Compounded products can be appropriate in some cases but deserve an informed discussion.
How often are blood tests needed on hormone therapy?
Baseline labs come first, followed by repeat testing after a few weeks to months, and then periodically. The schedule depends on the hormone, the route and the patient. Symptoms are evaluated alongside numbers.
Can hormone therapy help with weight loss?
It can help indirectly through energy, sleep, mood and muscle maintenance, but it is not a weight loss drug. Patients who want body composition change usually combine hormone care with nutrition, exercise and, where appropriate, medical weight management.
Who should not use systemic hormone therapy?
Patients with active or past hormone-sensitive cancers, unexplained vaginal bleeding, active blood clots, severe liver disease or certain other conditions may not be candidates. A full history and exam determine whether therapy is appropriate.
Can the delivery method be changed later?
Yes, in most cases. A patient can move from pills to patches, from creams to injections, or between other routes as needs and tolerance change. Pellets are the exception in the short term, since the dose continues until it is used up.
