Topical testosterone is a transdermal form of testosterone that delivers the hormone through the skin. Topical testosterone comes in the form of gels, creams, and patches. In Canada, all currently marketed topical products are gels. Many patients find it a convenient and less invasive alternative to injections.
Unlike injectable and oral forms, topical testosterone contains the unmodified form of the hormone rather than an ester such as cypionate, enanthate, or undecanoate. The skin acts as a natural barrier, allowing for gradual absorption and stable daily levels.
How It’s Used
Topical testosterone products are applied once daily, usually to the upper arms, shoulders, or torso, depending on the product. The hormone is absorbed through the skin into the bloodstream, producing relatively stable levels throughout the day. Consistent timing and proper application are important for maintaining reliable results. Because of this daily routine, missed doses or inconsistent application can affect how well the treatment works.
All topical products must be allowed to dry completely before dressing to avoid accidental transfer to others through skin contact.
Benefits
Topical testosterone therapy appeals to many users because it avoids injections and allows for precise daily dose adjustments. It produces smoother hormone levels with fewer peaks and valleys compared to injections. It also eliminates the need for clinic visits for administration, giving patients more control over their treatment.
For patients starting testosterone therapy, topical formulations can also make it easier to monitor hormone response and side effects before switching to longer-acting options like injectables.
Drawbacks and Considerations
Despite its convenience, topical therapy comes with some drawbacks. Because testosterone is delivered through the skin, there is a risk of unintentional transfer to partners, children, or pets if precautions are not taken. The application site should be covered with clothing once the gel has dried, and hands should be washed thoroughly after application.
Some patients experience mild skin irritation or redness at the application site. Others find the daily routine difficult to maintain over time, especially compared to less frequent dosing options like injections. Topical products are also typically more expensive than injectable formulations and may not be covered under all insurance plans.
Products Available in Canada
Three topical testosterone products are currently available in Canada:
- AndroGel (Pump and Sachet) – Manufactured by BGP Pharma ULC.
- Testim – Produced in partnership with Endo Operations and distributed in Canada by Knight Therapeutics.
- Taro Testosterone Gel – Generic version manufactured by Taro Pharmaceuticals.
These products differ in carrier formulation and absorption rates but have comparable clinical outcomes when used as directed.
Because multiple products are available, shortages are often easier to manage by switching between gels, although differences in format and dosing still matter.
Public Coverage
Topical testosterone products may be covered by provincial and territorial drug plans in Canada, but coverage usually requires approval before it is paid for. This approval is based on medical criteria set by each plan. Coverage can also depend on the specific product and where you live.
Shortages and Supply Context
Topical testosterone products have experienced fewer shortages than injectable formulations, but disruptions do occur. Factors such as manufacturing delays, packaging shortages, or demand surges can temporarily affect supply. Because multiple manufacturers produce topical products, patients and prescribers usually have more flexibility when one product becomes unavailable, often by switching between gels.
Topical testosterone offers a convenient, effective, and well-tolerated option for many patients. Daily application and transfer precautions require consistency, but topical products provide a stable and needle-free option that remains an important part of testosterone care in Canada.
