Quick Answer
Testosterone therapy comes in several forms, including injections, gels and creams applied to the skin, pellets placed under the skin, patches, oral capsules and a nasal gel. Each form works, but they differ in how often you use them, how steady your levels stay and which side effects are most likely. No single form is best for everyone. The right choice depends on your lab results, health history, lifestyle and preferences.

Injections
Testosterone injections are given into a muscle or just under the skin. Common schedules range from weekly to every two weeks, and many people learn to give them at home. A long-acting form is given about every 10 weeks, but only in a medical office.[1]
Because levels rise after a shot and fall before the next one, some men notice changes in energy or mood between doses.[2] Shorter dosing intervals can help even this out. Injection site soreness can also occur.
Injections allow fairly precise control over the dose. They can be a practical fit for men who are comfortable with needles or who can come in for office injections.
Gels and Creams
Testosterone gels are applied to the skin once a day, usually on the upper arms, shoulders or thighs depending on the product. They are one of the most common forms in the United States.[1] Daily use tends to keep levels fairly steady.
The main drawback is transfer. Testosterone on the skin can pass to a partner or child through contact, so it is important to let it dry, cover the area and wash your hands.[2] Skin irritation is also possible. Some testosterone creams are made by compounding pharmacies, and compounded products are not FDA-approved.
The best testosterone form is one that fits your health, routine and comfort level.
Pellets
Testosterone pellets are small implants placed under the skin, usually near the hip or buttocks, during a brief in-office procedure. They release testosterone slowly over about three to six months.[3]
Pellets mean fewer doses to remember and no transfer risk. Possible side effects at the site include swelling, pain, bruising and, rarely, a collection of blood under the skin.[3] Because pellets release over months, adjusting the dose may mean waiting until the next placement.
Pellets may suit men who want a low-maintenance routine and have already found a steady dose that works for them.
Patches, Oral and Nasal Options
A few other forms are available:[2]
- Patches are applied daily to the arm or torso. Skin rash or irritation is common.
- Oral testosterone undecanoate is a capsule taken by mouth. Older oral forms could harm the liver, while this newer type is absorbed differently.
- Nasal gel is used in each nostril three times a day. It lowers the risk of skin transfer but requires frequent dosing.
These options can be useful for men who prefer to avoid needles or skin gels, though they may be less convenient or less commonly used.
How to Compare Your Options
Every form of testosterone carries the same core risks, including higher red blood cell counts, lower sperm production and a rise in blood pressure. The FDA has added blood pressure warnings across testosterone products.[4]
Questions that can help guide the choice include:
- Are you comfortable with needles or a small procedure?
- Do you have close skin contact with young children or a partner?
- Do you prefer daily routines or fewer, longer-lasting doses?
- What does your insurance cover?
- How have your labs and symptoms responded so far?
Follow-up labs matter with every form. See our article on testosterone therapy lab monitoring for details.
How We Approach Testosterone Options at Lake Forest Regenesis
Allana starts by confirming low testosterone with labs and reviewing your symptoms, health history and goals. If testosterone therapy is a good fit, she walks through the options that may suit you, including how often each is used, possible side effects and what follow-up involves. Your preferences, family plans and daily routine are part of the decision. She then uses follow-up labs and check-ins to see how treatment is working.
When to See a Provider
Call 911 for chest pain, shortness of breath, sudden weakness or trouble speaking. Seek urgent care for pain or swelling in one leg, or for redness, warmth or drainage at an injection or pellet site with fever. Book a visit if your symptoms swing between doses, a gel or patch is irritating your skin, or a partner or child may have had contact with your testosterone gel.

Frequently Asked Questions
Which form of testosterone works best?
All approved forms can raise testosterone levels. The best one depends on your labs, side effects, lifestyle and how your body responds.
Can I switch forms later?
Often, yes. Some men change forms because of side effects, convenience or cost. Your provider can plan the switch and recheck labs afterward.
Do pellets or injections avoid the transfer risk of gels?
Yes. Injections, pellets, oral capsules and nasal gel do not carry the skin-to-skin transfer risk that gels and creams do.
Does the form affect fertility?
All forms of testosterone therapy can lower sperm production. If you may want children, talk with your provider before starting any form.
