Comparing absorption, blood counts, skin transfer risk, and daily routine so you can choose with your doctor.
Choosing between testosterone cream and injections involves trade-offs. Injections are usually given every one to two weeks, or as your prescriber directs, and they create peaks and troughs. Creams are applied daily for steadier levels but can transfer to partners and children through skin contact. One retrospective study found high red blood cell counts far more often with injections than with gels. Every form of TRT suppresses sperm production. Your doctor should guide the choice.
The thought of a needle every week makes some men uneasy. Others feel great a few days after each shot, then drained before the next. If either sounds familiar, you may be weighing testosterone cream vs. injections. At King’s Pharmacy and Compounding Center, our compounding pharmacy team hears this question often from men starting or adjusting testosterone replacement therapy (TRT).
Both forms can raise testosterone. They just do it in different ways, with different routines and different risks. Some of those differences show up in your lab work. Others show up at home, like the need to keep your skin covered around your kids.
This guide covers how each form works, what one well-known study found about blood counts, and how to lower skin transfer risk. It also explains how a compounded cream can be tailored by prescription. The goal is a better conversation with your doctor, not a replacement for it. Only your prescriber can decide which form fits your health history.
How Testosterone Injections Work
Testosterone injections place the hormone into muscle or under the skin, where it is released into the bloodstream over several days. Levels typically rise after each shot and drift down before the next one. Prescribers often schedule injections every one to two weeks, though some prefer more frequent, smaller injections.
Injectable testosterone is usually an esterified form, such as testosterone cypionate or enanthate, in an oil base. The ester slows release so the hormone enters the blood gradually. Still, the pattern is not flat.
Many men notice this rhythm. Energy, mood, and libido may feel strongest in the days after a shot and fade toward the end of the cycle. That swing is one reason some prescribers shorten the interval between injections.
Injections offer some clear advantages:
- No daily application to remember
- No risk of passing hormones to others through skin contact
- Generic injectable testosterone is often among the less costly options
- Shots can be given at a clinic or, with training, at home
Some men also like that a shot schedule is easy to track. Your lab draws can be timed to a point in the cycle, which helps your prescriber read the results.
The downsides include needles, occasional soreness at the injection site, and those peaks and troughs. As the research below shows, injections have also been linked to higher red blood cell counts.
How Compounded Testosterone Creams Work
A compounded testosterone cream is rubbed into clean, dry skin each day, on the area your prescriber recommends. The hormone absorbs through the skin and enters the bloodstream over the course of the day. Because you apply it daily, levels tend to stay steadier than with a shot every week or two.
Commercial testosterone gels come in fixed strengths and fixed bases. A compounded cream is different. It is prepared from a prescription for one patient, and the prescriber specifies both the strength and the base.
That flexibility can matter for men who react to an ingredient in a commercial product or who need a strength that is not commercially available. Some men also simply prefer the feel of a cream over an alcohol-based gel.
Absorption varies from person to person. Skin thickness, the application site, and the base all affect how much hormone reaches your blood. That is why follow-up lab work matters with creams just as much as with injections. If you are still learning about low testosterone itself, our guide to BHRT for men and andropause covers the basics. It is also worth knowing that the AUA testosterone deficiency guideline calls for both low testosterone levels and related symptoms before a diagnosis is made.
Testosterone Cream vs. Injections: What the Research Says About Blood Counts
Testosterone can raise hematocrit, the share of your blood made up of red blood cells. A 2015 retrospective study found elevated hematocrit far more often in men using injections than in men using a topical gel. The study had real limitations, but it offers a useful starting point for comparison.
Researchers at Baylor reviewed the records of men on three forms of TRT: 47 using gel, 57 using injections, and 74 using pellets. They defined erythrocytosis as a hematocrit of 50% or higher. In the Pastuszak 2015 study in Sexual Medicine, it occurred in 66.7% of injection users, 35.1% of pellet users, and 12.8% of gel users.
Injection users also developed it soonest, at roughly 10.5 months on average. They had the highest testosterone levels too. The researchers found no significant PSA increases in any group.
Why does hematocrit matter? Thicker blood may raise concerns about clots and heart health, so prescribers check it with routine blood work. If it climbs too high, your doctor may change your treatment plan.
Be aware of the limits. The study was a look back at existing records, not a randomized trial, and the groups were small. It studied commercial gels instead of compounded creams, so results may differ. The authors themselves said the choice of formulation should account for patient preferences.
“The best testosterone form is the one your doctor can monitor and you can use consistently.”
Skin Transfer Risk: Protecting Partners and Children
The biggest safety trade-off with topical testosterone is secondary exposure. Hormones left on your skin can rub off onto a partner or child. The FDA added a boxed warning to topical testosterone products in 2009 after reports of children showing signs of early male development following skin contact.
You can read more on the FDA’s postmarket drug safety information page. The warning applies to topical testosterone broadly. A compounded cream contains the same hormone, so the same basic risk applies.
The encouraging news is that simple habits lower the risk a lot. Ask your prescriber and pharmacist about precautions like these:
- Wash your hands with soap and water right after applying.
- Let the cream dry, then cover the site with clothing.
- Wash the application site before close skin contact with others.
- Keep children away from the site, your towels, and worn shirts.
- Store the cream out of children’s reach.
If a child or partner shows unexpected changes, such as new body hair, acne, or early signs of puberty, contact a doctor and mention the possible exposure. Tell your prescriber as well, since your routine may need a closer look.
Injections remove this concern entirely. That is one reason men with young children at home sometimes lean toward shots.
Testosterone Cream vs. Injections: Comparing Cost, Convenience, and Routine
When men compare testosterone cream vs. injections side by side, the practical details often decide it. Here is a brief look:
- Frequency: Injections every one to two weeks, or as prescribed. Creams daily.
- Level pattern: Injections rise and fall. Creams tend to stay steadier.
- Needles: Required for injections. None for creams.
- Transfer risk: None with injections. Real with creams, so precautions matter.
- Blood counts: Higher erythrocytosis rates with injections in one study. Both need monitoring.
- Cost: Varies by insurance, prescription, and pharmacy. Compounded creams are often not covered, so ask before you start.
- Fertility: Both suppress sperm production.
That last point deserves attention. TRT in any form signals your brain to cut back on the hormones that tell the testes to make sperm. In two phase III trials reported by Kim and colleagues in 2015, topical testosterone gel restored testosterone but markedly reduced sperm concentration.
In those same trials, enclomiphene maintained sperm concentration. If you hope to father children, ask your doctor about alternatives such as enclomiphene before starting TRT. Enclomiphene is not FDA-approved and has its risks, so that conversation belongs with your prescriber.
How a Compounding Pharmacy Customizes Testosterone Cream
A compounding pharmacy prepares testosterone cream from an individual prescription. Your prescriber chooses the strength and can request a specific base, such as one free of an ingredient you react to. The pharmacist then compounds, labels, and counsels you on safe use.
The base matters more than many men expect. Different bases feel different on the skin and can affect how well the hormone absorbs. If your lab results call for a change, your prescriber can adjust the strength without being limited to commercial options. Our post on customized dosages in hormone therapy explains why that flexibility can help.
It is important to be clear about what compounding is not. Compounded testosterone cream is not FDA-approved, and it is not equivalent to an FDA-approved brand. It is made to meet an identified patient need that a commercial product does not.
King’s Pharmacy is NABP accredited, a PCCA member, and licensed in 13 states. Our pharmacists review each prescription, prepare it to quality standards, and walk you through application, transfer precautions, and storage. Learn more on our men’s health page.

Final Thoughts
The testosterone cream vs. injection decision is not about which form is best for everyone. It is about which one fits your body, your lab results, and your life at home. Injections avoid skin transfer but may raise red blood cell counts more often. Creams offer steadier daily levels but require careful habits to protect the people around you.
Two takeaways stand out. First, whatever form you choose, regular lab monitoring is essential. Second, if fertility matters to you, raise it with your doctor before starting any TRT.

Frequently Asked Questions
Is testosterone cream better than injections?
Neither form is better for every man. Injections avoid daily application and skin transfer, while creams tend to produce steadier levels. Your prescriber will weigh your lab results, health history, household, and preferences to help you choose.
Does testosterone cream increase hematocrit levels?
Any form of testosterone therapy can raise hematocrit. In a 2015 retrospective study, elevated hematocrit was much less common in men using topical gel than in men using injections. Your doctor should still check your blood counts regularly on any form.
How do I keep testosterone cream from transferring to my family?
Wash your hands right after applying, let the cream dry, and cover the site with clothing. Wash the area before close skin contact with others. Ask your pharmacist for a full list of precautions for your specific prescription.
Will testosterone cream or injections affect my fertility?
Yes. Testosterone therapy in any form can suppress sperm production. Men who want to father children should speak with their doctor about other options before starting treatment.
Is compounded testosterone cream FDA-approved?
No. Compounded medications, including testosterone cream, are not FDA-approved and are not equivalent to FDA-approved brands. They are prepared by a licensed pharmacy from a valid prescription to meet the needs of individual patients.
