Topical Testosterone

Topical testosterone is absorbed through the skin into the lymphatic system — a transdermal route that bypasses first-pass liver metabolism. Once-daily application keeps your blood levels steady through the day, instead of the peak-and-trough swings you get with weekly injections.

Apply the prescribed dose once a day to thin-skinned areas — inner arms, wrists, lateral abdomen, inner thighs, or scrotum — and avoid fattier sites where absorption is unreliable. Let the gel dry fully before dressing, and wash your hands. Dr. Salim’s protocol gives you the exact site rotation, dose, and timing.

Topical testosterone absorbs quickly — blood levels peak within hours of application. Most men notice subtle shifts in energy, mood, and libido inside the first few weeks. The fuller effect builds gradually as levels stabilize, typically over two to three months of consistent daily use.

The most common are skin reactions at the application site (redness, irritation, oily skin), acne, and shifts in libido or mood. Topical testosterone can also raise hematocrit and hemoglobin, and can move PSA — which is why ongoing bloodwork is part of the protocol, not an afterthought. The one most men ask about is hair loss: testosterone converts to DHT, and in men with a male-pattern predisposition, more DHT can accelerate thinning. It doesn’t cause hair loss in men who weren’t already going to lose hair, but it can speed up what was already on the cards. If thinning is a concern, our specialist can pair your protocol with hair-loss medication — oral or topical — that targets DHT directly.

Yes — skin-to-skin contact before the gel has fully absorbed can transfer testosterone to a partner, child, or pet. The mitigation is straightforward: wash your hands thoroughly after applying, let the site dry, and cover it with clothing. Avoid skin-to-skin contact at the application site for the first few hours, and don’t share towels or bedding before it’s dry.

Yes. Because topical testosterone is absorbed through the skin into the lymphatic system, it bypasses first-pass liver metabolism — the same reason it works as a daily gel rather than a pill. The hepatotoxicity risk that’s been associated with some older oral testosterone formulations isn’t seen with transdermal delivery. Liver enzymes are still tracked as part of routine bloodwork.

Yes. Like any form of TRT, topical testosterone signals your body to slow its own testosterone production, which can reduce sperm output and other fertility markers over time. If preserving fertility matters to you now or later, tell our health team during your assessment — there are fertility-sparing alternatives that support your body’s own production instead of replacing it.

Yes. Bloodwork confirms eligibility, sets your starting dose, and lets our specialist monitor your markers over time. You can run the panel at any local lab — LifeLabs, APL, Dynacare, or your hospital lab all work. The markers that matter for topical testosterone are Total Testosterone, SHBG (or Free Testosterone), LH, PSA, and Hematocrit. If you’ve had recent bloodwork, share it during your assessment as context — but our panel includes proprietary markers Dr. Salim needs before prescribing, so you’ll still complete the Gambit bloodwork.
