Most men with low testosterone are told they have two options: do nothing, or jump on a generic protocol with no real follow-up. Neither one fits how I practice. Injection therapy works for a specific kind of patient — the one who wants tight dose control, fast titration, and the option to manage their own delivery between visits. Done right, it produces stable energy, recovery, and body composition without the swings men hear about. Done wrong, it produces the same swings, plus elevated hematocrit, suppressed natural production, and side effects nobody warned about. The difference is the protocol and the monitoring.
What is this treatment?
Testosterone injection therapy uses bioidentical testosterone administered intramuscularly or subcutaneously on a defined schedule. In Travis's practice the ester is testosterone cypionate, exclusively — standardizing on a single ester gives him a tighter clinical baseline across patients and the most consistent symptom response. Weekly dosing produces the smoothest hormone curve and is what I typically recommend. Self-injection training is part of the program. Once you understand the technique, the maintenance is about fifteen seconds a week.
How we approach it at Revitalize
We start the same way every TRT conversation should start: a comprehensive hormone panel and an honest clinical conversation. Total testosterone, free testosterone, SHBG, estradiol, DHEA, PSA, CBC, and a full metabolic panel. We talk through your symptoms, your history, your goals, and the specific tradeoffs between pellets and injections so you can make an informed choice. Once we initiate, the first follow-up labs run at 8-12 weeks. Dose is calibrated based on the data and how you actually feel — not based on what is convenient for the protocol.
Who is a good candidate
- ✓Men with confirmed low testosterone on lab work plus corresponding symptoms
- ✓Patients who want tight dose control and the ability to titrate quickly
- ✓Men comfortable with self-injection (or willing to learn — the training is straightforward)
- ✓Patients who have tried pellet therapy and want to try a different delivery method
- ✓Men who travel frequently and want a portable, schedule-flexible protocol
- ✓Patients with specific lab patterns (e.g., high SHBG) where injection dosing produces better free T
Not appropriate for
- ×Men with active prostate cancer or unevaluated PSA elevation
- ×Patients with polycythemia (elevated hematocrit) without hematology coordination
- ×Untreated obstructive sleep apnea — should be evaluated before starting TRT
- ×Men actively trying to father children — injection TRT will suppress sperm production
- ×Patients unwilling to commit to follow-up labs (this is non-negotiable on injection therapy)
- ×Severe needle aversion that cannot be addressed with appropriate accommodation
What to expect at your appointment
1
Comprehensive consultation: We review your symptoms, history, medications, and goals. We discuss pellet vs injection in detail so you can choose the delivery method that actually fits your situation.
2
Lab work: Full hormone panel — total and free testosterone, SHBG, estradiol, DHEA, PSA, CBC, metabolic panel. We review every value with you, not just the testosterone number.
3
Treatment plan: Specific cypionate dose, specific frequency (weekly is the default cadence), specific route (intramuscular or subcutaneous). We discuss why each choice was made for your physiology.
4
Self-injection training: In-office, hands-on. Most patients are comfortable doing it themselves by the end of the first visit. Subcutaneous and intramuscular techniques are both taught.
5
8-12 week reassessment: Labs are repeated. Dose is calibrated based on the data and your symptom response. This is where the precision happens.
6
Ongoing monitoring: Labs at intervals appropriate to your protocol. We track testosterone, hematocrit, estradiol, PSA. We adjust as needed. This is a long-term clinical relationship, not a prescription handoff.

Frequently asked questions
Testosterone replacement therapy requires comprehensive lab work, in-person clinical evaluation, and ongoing monitoring. Individual responses vary. Not all patients are candidates. Testosterone therapy is contraindicated in active prostate cancer and certain cardiovascular conditions; specific patient situations require specialist coordination.

What a Typical Week Looks Like
The rhythm of weekly TRT injections — set up to be invisible.
The biggest concern most men have about injection therapy is that it'll dominate their week. It doesn't. Once you're trained and your dose is dialed in, the protocol is a 15-second weekly task. Here's what the rhythm of a typical week actually looks like in Travis's practice:
Injection day
You pick the day that fits your schedule — many patients pick Sunday morning or Monday morning so the rhythm anchors to the week. The injection itself takes about 15 seconds: alcohol swab, draw the dose, inject (subcutaneous or intramuscular based on your protocol), discard. Done.
Days 1-3 post-injection
Testosterone level peaks in the 24-48 hour window after injection. Most men feel this as steady energy and good sleep — not a dramatic spike. The peak with weekly cypionate at a sensible dose is well within the optimal range for most men.
Days 4-6
Levels gradually decline. With weekly dosing, the trough at day 7 is still in a clinically optimal range for most patients. Mid-week is typically when men feel their best — energy, recovery, training response, libido all running well.
End of week (day 6-7)
The 'trough' point — your level is at its lowest for the week. Most men don't notice this because the trough is still optimal. If you DO notice mid-week-trough symptoms (energy dip, mood dip, libido dip), that's clinical data we use at the next lab to either tighten the dose, switch to twice-weekly dosing, or address with another lever.
Lab cadence
First labs at 8-12 weeks after starting. Then every 6-12 months once you're stable, depending on the protocol. We track total T, free T, SHBG, estradiol, hematocrit, PSA. Every lab is reviewed with you and the protocol is calibrated based on what the data shows.
Lab Patterns We Adjust To
When the labs tell us injections are the better tool.
Some lab patterns respond meaningfully better to injections than to pellets. This is part of why Travis runs both protocols — the lab pattern often points to which delivery method will produce a better result. Common patterns where injection therapy is the clear answer:
High SHBG with low free testosterone
Sex hormone binding globulin binds testosterone and renders it biologically inactive. A man with total T of 600 and SHBG of 70 has a free T problem even though his total looks fine on paper. Pellet dosing, which delivers a relatively fixed total dose, often can't push free T high enough to fix the symptoms. Weekly injection therapy gives us the room to titrate the dose up and pull free T into optimal range — this is the most common 'injections are better' scenario in our practice.
Estradiol that runs high on pellet therapy
Some patients aromatize testosterone aggressively. On pellets — which deliver a continuous, slightly higher peak-equivalent dose — estradiol can run uncomfortably high (water retention, nipple sensitivity, mood). Switching to weekly injections at a lower per-week dose often resolves the estradiol problem without losing testosterone benefit.
Hematocrit creep on TRT
Both pellets and injections can elevate hematocrit, but the dose-response is more predictable on injections — which means we can lower the dose precisely to stabilize hematocrit without going under-dosed on testosterone. Therapeutic phlebotomy is sometimes part of the picture; we coordinate when needed.
Recovery-focused or athletic patients
Men training seriously who want to optimize testosterone for body composition and recovery often prefer the dose-control granularity of weekly injections. The protocol can be tuned more precisely to the training cycle and to specific lab markers like free T and IGF-1.
Bi-weekly pellet patients reporting end-of-cycle drop-off
If you finished a pellet cycle and felt clearly worse in the last 4-6 weeks before the next insertion, that's data. Injections eliminate that drop-off pattern entirely because the dose is delivered weekly rather than over a 3-5 month curve.
Decision Framework
Injections or pellets — quick self-identification.
The actual choice happens at the consultation with your labs in front of us. But if you want a quick sense of which delivery method probably fits you better before booking, here's the heuristic Travis uses:
Injections probably fit if…
- You have high SHBG (or have been told your free T is low despite normal total T)
- You aromatize aggressively or have run high estradiol on prior TRT
- You want tight dose control and are willing to do labs more frequently early on
- You travel often and want a portable protocol
- You're focused on training, body composition, or recovery and want fine-grained tuning
- You don't mind a weekly 15-second self-injection task
Pellets probably fit if…
- You have a stable lab pattern with normal SHBG
- You strongly prefer set-it-and-forget-it convenience
- You don't want to manage a weekly injection task
- You like the idea of a single in-office procedure every 3-5 months
- You've researched both and the steady-release model appeals to you
- You aren't pursuing fine-grained training/recovery optimization
Not sure? That's normal — and it's exactly what the consultation is for. Travis will run your labs, walk through both options with the data in hand, and recommend the one that fits your physiology and life. If you start on one and want to switch later, that path is also straightforward. Read about Biote pellet therapy here or see the men's hormone therapy overview.
