TRT Treatment Comparison
A comprehensive comparison of testosterone delivery methods to help you choose the right treatment approach for your lifestyle and needs.
Choosing Your Delivery Method
Testosterone can be delivered to your body through several different methods, each with distinct advantages and drawbacks. The "best" option depends on your personal preferences, lifestyle, medical history, and how your body responds to treatment.
All FDA-approved testosterone formulations can effectively raise testosterone levels when used correctly. The key is finding the delivery method you'll use consistently while achieving stable hormone levels with minimal side effects.

Testosterone Transdermal Systems Comparison
| Delivery Method | Absorption Rate | Dosing Frequency | Skin Irritation Risk | Cost Estimate | Clinical Evidence |
|---|---|---|---|---|---|
| Injections (IM/SubQ) | 95-100% | Weekly–EOD | Low | $30-70/mo | Very Strong |
| Topical Gels | 10-15% | Daily | Moderate | $50-600/mo | Strong |

*Averaged over months between insertions. Absorption rates for transdermal systems vary significantly based on application site, skin thickness, and individual pharmacokinetics.
Testosterone Patches (Transdermal Systems)
Testosterone patches like Androderm deliver testosterone through the skin using a controlled-release membrane. Applied nightly, they mimic the body's natural circadian rhythm of testosterone production, peaking in the early morning hours. Clinical trials have shown patches can reliably raise serum testosterone to physiological ranges in most men.
However, patches carry the highest skin irritation rate of any transdermal system—up to 60% of users report some degree of contact dermatitis. Rotating application sites between the back, abdomen, thighs, and upper arms with at least 7-day intervals is essential. Many men ultimately discontinue patches due to adhesion issues, especially in hot or humid climates.
The Endocrine Society notes that patches may not achieve adequate testosterone levels in larger men, sometimes requiring multiple patches applied simultaneously—further increasing skin irritation and cost.
Testosterone Gels (Topical Transdermal)
Topical gels (AndroGel, Testim, Fortesta) are the most commonly prescribed transdermal testosterone formulation. Applied daily to the shoulders, upper arms, or abdomen, gels provide relatively stable serum testosterone levels without the peaks and troughs associated with injections. Most men achieve therapeutic levels within 1-2 weeks of starting treatment.
The primary clinical concern with gels is secondary transfer—testosterone can be transferred to women and children through direct skin contact, potentially causing virilization. The FDA requires a black box warning for this risk. Patients must wash hands thoroughly, cover application sites, and avoid skin-to-skin contact until the gel is fully absorbed.
Absorption rates vary significantly between individuals (10-15% bioavailability on average), meaning some men require higher doses or alternative methods to achieve target levels. Generic options have significantly reduced costs compared to brand-name formulations.
Topical Testosterone Creams (Compounded)
Compounded testosterone creams are custom-formulated by compounding pharmacies, often in higher concentrations than commercially available gels. Applied to the scrotum or inner thigh for enhanced absorption, creams can achieve higher DHT conversion and may provide superior symptom relief for some men, particularly for libido and sexual function.
Because creams are compounded, dosing can be precisely tailored—a significant advantage for men who need non-standard concentrations. They tend to cause less skin irritation than patches and are generally more affordable than brand-name gels. However, quality can vary between compounding pharmacies, and FDA oversight is less stringent than for manufactured products.
Scrotal application has gained popularity in TRT communities due to higher absorption rates and increased 5-alpha reductase activity in scrotal skin, potentially enhancing DHT-mediated benefits. Clinical data on this route is more limited than traditional application sites.
Injectable Testosterone
Injectable testosterone (cypionate and enanthate) remains the gold standard for TRT, offering the highest bioavailability, lowest cost, and most precise dose control. Administered intramuscularly or subcutaneously, injections bypass first-pass metabolism entirely, ensuring predictable serum levels based on dose and frequency.
The primary limitation is pharmacokinetic fluctuation: weekly injections produce supraphysiological peaks 24-48 hours post-injection followed by a gradual decline. More frequent dosing (every 3.5 days or every other day) significantly reduces this variance and is increasingly recommended by endocrinologists specializing in hormone optimization.
A landmark 2023 meta-analysis in the Journal of Clinical Endocrinology & Metabolism confirmed that injectable testosterone produces the most consistent improvements in body composition, sexual function, and mood when dosed appropriately and monitored with regular bloodwork.
