TRT Delivery Methods: Which One Is Right for You?

Your doctor confirmed your low testosterone symptoms are real and your labs back it up. You're ready to do something about it. But then you find out there are six different ways to take it — shots, gels, creams, pellets, patches, a nasal spray, and even a pill — and nobody takes five minutes to explain what the actual differences are.

That's what this article is for.

Every TRT delivery method works. They all raise testosterone. But they don't all work the same way, cost the same, or fit every lifestyle. The right choice depends on how you live, how often you want to deal with your medication, whether you have kids or a partner at home, what your budget looks like, and what your labs say.

Here's the honest breakdown of every FDA-approved TRT delivery method — what each one does, what it costs, who it's best for, and what the real tradeoffs are.

Why the Delivery Method Matters More Than You Think

All TRT raises testosterone, but the delivery method determines how stable your levels are, how much you're managing day-to-day, and what side effects you're more or less likely to run into.

Injections give you weekly or biweekly peaks and troughs. Pellets stay flat for months. Gels require daily application and carry a black box FDA warning about transferring testosterone to kids or partners through skin contact. The method isn't just a preference — it affects how you feel and who else in your house might be affected.

The FDA has approved all of the methods we'll cover here (Shoskes et al., 2016). WADA classifies testosterone as a prohibited S1 anabolic agent. If you compete in any tested sport, every single delivery method requires a Therapeutic Use Exemption (TUE) before you start — there are no exceptions (Ramasamy et al., 2020).

Now let's get into the actual methods.

Testosterone Injections (Cypionate and Enanthate)

Injections are the most common TRT delivery method for a reason. They're cheap, effective, and flexible.

Testosterone cypionate and testosterone enanthate are the two standard injectable forms. Both are oil-based esters dissolved in cottonseed or sesame oil, injected either intramuscularly or subcutaneously. The FDA-approved label for testosterone cypionate (200 mg/mL) states a half-life of approximately eight days when injected intramuscularly (Shoskes et al., 2016). Enanthate has a similar half-life, around seven to ten days.

Most protocols run 100-200 mg per week, either as one weekly injection or split into two smaller injections (twice weekly helps keep levels more stable). Subcutaneous injections — a smaller needle into fat tissue rather than muscle — have become more popular because they're easier to self-administer and produce comparable serum levels (Olson et al., 2014).

What cypionate costs: Generic testosterone cypionate runs $20-50 per vial (200 mg/mL, 10 mL multi-dose). At a typical dose of 100 mg per week, one vial lasts 8-10 weeks. Out of pocket, that's roughly $30-60 per month — the cheapest TRT option by a wide margin. GoodRx often brings it below $30 at major pharmacies.

Who injections are best for:

• Anyone who wants the most cost-effective option
• People who don't mind weekly self-injection (it becomes routine fast)
• Those where budget is a real consideration
• Men or women who want precise dose control (easy to adjust up or down)

The real tradeoffs: The trough-and-peak pattern of weekly injections can cause some men to feel great mid-week and sluggish by injection day. Splitting into twice-weekly doses largely fixes this. Hematocrit (red blood cell count) can rise over time and needs monitoring — your provider should check it every 3-6 months (MacIndoe et al., 1997). And yes, you have to be okay with needles.

Testosterone Gels (AndroGel, Fortesta, Axiron)

Gels are the second most common TRT delivery method and the most commonly advertised one. AndroGel alone generated over $1 billion in annual sales at its peak. But there are real tradeoffs the commercials don't mention.

AndroGel is available in 1% and 1.62% concentrations. Fortesta and Axiron are alternative gel and solution formulations applied to different body areas (shoulders, thighs, or the axilla/armpit). All are FDA-approved. All require daily application.

The pharmacokinetics work differently than injections: testosterone absorbs through the skin slowly, maintaining more stable daily levels without the weekly peaks and troughs. For men who hate injections and can afford the cost, this is genuinely appealing.

What gels cost: Brand name AndroGel runs $400-500 per month. Most major insurance plans cover it with prior authorization, which your provider can handle. Generic testosterone gel has lowered costs significantly — check GoodRx before paying retail. Still, even generic gel typically runs $50-150 per month, more than injectable cypionate.

The FDA black box warning you need to know:

The FDA requires a black box warning on ALL testosterone gels and solutions. Secondary exposure — meaning testosterone transferring from your skin to someone else who touches you — can cause serious harm to women and children.

In children, even small amounts of transferred testosterone can cause premature puberty, aggressive growth, and bone age advancement. In women, it can disrupt their own hormonal balance. The FDA first issued this warning in 2009 after multiple pediatric cases involving accidental exposure (Pastuszak et al., 2015).

If you choose gel, you must:

• Let it dry completely before contact (typically 2-4 hours)
• Wash your hands thoroughly every time
• Apply only to areas that stay covered by clothing
• Keep children and partners away from application sites

For families with young children at home, this is a significant consideration. Many physicians recommend injections or pellets instead precisely for this reason.

Compounded Testosterone Creams

Compounded testosterone creams are not the same as FDA-approved gels. They're made by compounding pharmacies to custom concentrations — typically 100 mg/mL or 200 mg/mL — and aren't subject to the same standardized manufacturing as commercial products.

The same secondary exposure warning applies. Women ask us frequently: "Where do I apply testosterone cream?" For women using testosterone cream therapeutically (it's prescribed off-label for libido and energy), application sites are typically the inner thigh, inner arm, or labia — areas less likely to cause accidental transfer. Women using testosterone cream should shower 4-6 hours after application to reduce transfer risk to partners and children.

Cost for compounded creams: Varies by pharmacy and concentration, but typically $60-150 per month — in between generic gel and injectable cypionate.

Testosterone Pellets (Testopel)

Testopel is the only FDA-approved subcutaneous testosterone pellet. A trained physician implants small crystalline pellets (about the size of a grain of rice) just under the skin — usually the upper buttock — via a small incision under local anesthesia. Each implant session places 10-12 pellets and releases testosterone slowly over 3-6 months (Pastuszak et al., 2015).

The appeal is obvious: zero daily or weekly medication management. You come in every 3-6 months, and that's it.

What pellets cost: $500-700 per insertion procedure, not typically covered by standard insurance (though some plans with prior authorization do cover it). At 2-4 insertions per year, that's $1,000-2,800 annually. If your insurance doesn't cover it and you're paying out of pocket, this is significantly more expensive than injections.

Who pellets are best for:

• People who genuinely cannot manage weekly injections or daily applications (travel, work schedule, compliance issues)
• Anyone who wants the most "set it and forget it" approach
• Those with good insurance coverage or who can absorb the cost

The real tradeoffs: You can't easily adjust the dose once pellets are inserted — you're committed until they absorb. If your dose turns out too high or too low, you wait. Some patients also develop minor insertion site reactions or infections (rare but possible). And unlike injections, you can't just stop — the pellets continue releasing for months whether you want them to or not.

Testosterone Patches (Androderm)

Androderm is the primary FDA-approved testosterone patch. You apply a new patch daily, typically to the back, abdomen, or upper arm, and change it at roughly the same time each day. Patches deliver testosterone transdermally at a slower, more controlled rate than gels.

Patches were more popular 15-20 years ago. Today, most patients who might choose a patch end up opting for gels or injections instead.

What patches cost: Brand-name Androderm runs $250-400 per month, often covered by insurance with prior auth. Generic patches are less expensive.

Why patients frequently switch away: Skin irritation at the application site is the most commonly reported issue — redness, itching, and blisters affect a meaningful percentage of users. Patches must stay on during exercise, showering, and sleep, which some people find inconvenient. For most patients, other delivery methods offer a better experience at comparable or lower cost.

Nasal Testosterone Gel (Natesto)

Natesto is FDA-approved, and unlike every other TRT delivery method, it doesn't suppress the hypothalamic-pituitary-testicular (HPT) axis as aggressively as injections or systemic gels. It's applied with a small applicator inside each nostril — three times daily.

This matters if you care about fertility. Research using the MacIndoe et al. (1997) RCT framework for HPT suppression shows that systemic testosterone suppresses LH and FSH, which shuts down your own sperm production. Natesto's lower systemic absorption means the HPT axis stays more active, and sperm production remains better preserved compared to injections or gels (Ramasamy et al., 2020).

What Natesto costs: Approximately $500 per month. Rarely covered by insurance without significant prior authorization work.

Who Natesto is best for: Men who want TRT benefits but want to preserve fertility — particularly those considering having children in the next year or two. For everyone else, the cost-to-benefit ratio versus injections is hard to justify.

The real tradebacks: Three-times-daily dosing is genuinely inconvenient. It can't be used if you have nasal polyps or recent nasal surgery. Some men report a sneezing sensation after application.

Oral Testosterone (Jatenzo)

Jatenzo was FDA-approved in 2019 — the first oral testosterone approved in the United States in decades. It's a testosterone undecanoate softgel capsule taken twice daily with food (Winter, 2014).

Unlike older oral testosterone formulations that caused significant liver toxicity, Jatenzo is absorbed through the lymphatic system (via the gut's dietary fat pathway) rather than first-pass liver metabolism. This makes it substantially safer than black-market oral testosterone products, which remain hepatotoxic.

What Jatenzo costs: Approximately $600 per month. It's the most expensive standard TRT delivery method. Coverage varies widely by insurance.

Who Jatenzo is best for: Anyone with true needle phobia who can't bring themselves to do injections and finds gels impractical. The twice-daily pill is conceptually straightforward.

The real tradeoffs: Jatenzo carries a boxed warning for blood pressure increases — some patients see clinically significant spikes. It requires blood pressure monitoring throughout treatment. At $600/month versus $30-50/month for generic injectable cypionate, the cost differential is hard to ignore unless your insurance covers it.

How to Actually Choose: A Practical Guide

There's no universally "best" TRT delivery method. There's only the best one for your life, your labs, and your preferences.

Here's how to think through it:

Choose injections (cypionate or enanthate) if: You want the lowest cost, you're comfortable with needles or willing to learn, and you want maximum dose flexibility. This is what the majority of TRT patients use, and for good reason.

Choose gels or creams if: You genuinely can't do injections, don't have young children at home, and can manage daily application. Confirm your insurance covers it before committing.

Choose pellets if: You hate the idea of weekly or daily medication management and can afford $500-700 per insertion. Great for high-adherence patients who travel frequently.

Choose Natesto if: Fertility is a near-term priority. This is a specific use case, not a general recommendation.

Choose Jatenzo if: You have true needle phobia and can't manage topicals, and your insurance covers it. Monitor your blood pressure.

Choose patches only if: Your provider specifically recommends them for your situation. Most patients are better served by other options.

Safety Monitoring: What to Watch While on TRT

Regardless of delivery method, TRT requires ongoing lab monitoring. These aren't optional — they're how you stay safe.

Hematocrit/hemoglobin: Testosterone stimulates red blood cell production. If hematocrit climbs above 52-54%, blood becomes more viscous, raising clotting risk. This is more common with injections than topicals. Check every 3-6 months.

Estradiol (E2): Testosterone converts to estrogen via aromatase. Too much estradiol causes water retention, mood swings, and nipple sensitivity. Your provider monitors this and adjusts if needed — sometimes aromatase inhibitors are added (Winter, 2014).

PSA: A baseline PSA before starting TRT is standard. TRT is contraindicated if you have active prostate cancer. It does not appear to cause prostate cancer in men with normal prostates (Sena et al., 2020; Lincoff et al., 2023).

Cardiovascular markers: The Traverse Study — published in the New England Journal of Medicine and the largest cardiovascular outcomes trial for TRT to date — found that testosterone therapy in men with hypogonadism did not significantly increase rates of major cardiovascular events compared to placebo (Lincoff et al., 2023). But your baseline cardiovascular health still matters. Men with significant heart disease need closer monitoring.

Blood pressure (Jatenzo only): Oral testosterone specifically can raise blood pressure. Monitor it.

Cost, Coverage, and Getting Started

The cost of TRT varies more by delivery method than by almost any other factor. Generic injectable testosterone cypionate is legitimately affordable — $30-50/month. Brand-name gels and oral options can run 10-20x that.

What insurance usually covers: Most commercial insurance plans cover testosterone injections and branded gels (AndroGel) with prior authorization, which your provider submits. Coverage for compounded creams, Natesto, Jatenzo, and pellets is less consistent — you may need to appeal or pay out of pocket.

GoodRx works well here: For injectable cypionate especially, GoodRx or similar discount cards routinely cut the price to $20-35. Even branded gels are sometimes discounted.

The HEXIS approach: At HEXIS, every TRT protocol starts with labs. We run a full panel — total and free testosterone, LH, FSH, estradiol, SHBG, hematocrit, PSA baseline, metabolic panel — before recommending any delivery method. If you're not sure how to test testosterone levels or what the numbers mean, we explain all of it at your first appointment. Your numbers, your lifestyle, and your fertility goals all factor into the recommendation.

We prescribe all FDA-approved delivery methods and work with licensed compounding pharmacies for cream formulations. Telehealth appointments are available across Montana, Washington, Idaho, and Oregon. Great Falls patients can also be seen in clinic.

If you've been told your levels are "normal" but you still feel off, bring your actual number to the conversation. A level of 320 ng/dL is technically within range. It's also where many men feel exactly as tired and foggy as you do right now.

Schedule a consultation and we'll start with your labs, not guesswork.

Frequently Asked Questions

How do I know which TRT delivery method is best for me?

Start with your labs, your lifestyle, and your budget. Injections are the most cost-effective and offer the most dosing flexibility — most physicians recommend starting here. If you have young children at home, gels and creams require careful protocols to avoid transfer risk. If fertility preservation is a priority, Natesto is worth discussing specifically. Your HEXIS provider will review your full lab panel and recommend the best option based on your individual situation.

Does the delivery method affect how well TRT works?

All delivery methods raise testosterone effectively when dosed correctly. The differences are in stability (how steady your levels stay throughout the day/week), practical management, cost, and specific risks. Injections tend to produce slightly higher peaks than topicals. Splitting injections into twice-weekly doses rather than once-weekly produces more stable levels for most men.

Can testosterone gel or cream transfer to my child or partner?

Yes, and this is the FDA's most serious concern with topical testosterone. There is a black box warning on all testosterone gels and solutions specifically for this reason. Documented cases include children developing early puberty symptoms after exposure to a parent's TRT gel. If you choose a topical method, let it dry completely (2-4 hours), cover the application area, wash your hands thoroughly, and keep family members away from application sites.

How long after applying testosterone cream can I shower?

Most clinicians recommend waiting at least 4-6 hours after applying testosterone cream before showering to allow full absorption. Some formulations specify 2 hours minimum. Check the specific instructions for your formulation, and ask your provider if you're uncertain. Showering too early may reduce absorption and lower your effective dose.

Does TRT affect fertility?

Yes, all systemic testosterone delivery methods suppress LH and FSH through feedback inhibition of the hypothalamic-pituitary-testicular axis, which reduces sperm production (MacIndoe et al., 1997). This effect is reversible for most men when TRT is discontinued, but recovery can take 6-18 months. Men who want to preserve fertility while on TRT typically add hCG (human chorionic gonadotropin) to their protocol, or they use Natesto, which suppresses the HPT axis less aggressively. Some men choose not to start TRT at all and instead try enclomiphene, which stimulates the body's own testosterone production without suppressing fertility. If having children in the next 1-2 years is a consideration, tell your provider upfront — it changes the protocol.
