Testosterone Injections vs. Gels vs. Creams vs. Pellets: What's the Difference?

Choosing a Form of TRT

If you and your provider decide testosterone replacement therapy (TRT) is right for you, the next question is how to take it. Each form has its own benefits and trade-offs, and the best choice depends on your lifestyle, preferences, and how your body responds.

Injections

Testosterone injections (most commonly testosterone cypionate or enanthate) are the most widely used form of TRT.

• Pros: Affordable, effective, and dosing is easy to adjust. Can be given into the muscle or under the skin, often weekly or twice weekly
• Cons: Requires needles. Less frequent injections can cause peaks and dips in energy and mood
• Note: More frequent, smaller doses can provide steadier levels

Gels

Testosterone gels are applied to the skin daily, usually on the shoulders or upper arms.

• Pros: Steady daily levels, no needles
• Cons: Must be applied every day. There's a risk of transferring testosterone to partners or children through skin contact, so covering the area and washing hands is essential

Creams

Creams are similar to gels and are often compounded.

• Pros: No needles, flexible dosing
• Cons: Same transfer risk as gels, and absorption can vary

Pellets

Small pellets are placed under the skin, usually in the hip area, during a minor in-office procedure.

• Pros: Lasts three to six months, nothing to remember day to day
• Cons: Requires a procedure each time, dosing can't be easily adjusted once placed, and pellets can occasionally come out or cause local irritation

Other Options

• Oral testosterone: Newer FDA-approved capsules are available; they're taken twice daily and require blood pressure monitoring
• Nasal testosterone: Applied in the nose several times daily
• Patches: Worn on the skin daily, though skin irritation is common

How to Choose

Consider cost, convenience, comfort with needles, whether you live with children or a partner (for gel transfer risk), and how stable you want your levels to be. Whatever you choose, regular lab monitoring is essential.
