Testosterone Replacement Therapy: FAQ

Clinical guidelines require two separate blood tests confirming total testosterone below 300 ng/dL, combined with symptoms of low T. A single test is not sufficient, levels fluctuate, and testing should be done in the morning when levels peak. Dr. Ashar also evaluates free testosterone, estradiol, and metabolic markers for a complete clinical picture.

“Normal” reference ranges are broad and outdated. The lower limit of 300 ng/dL was established decades ago without accounting for symptom burden. Many men with levels of 300-450 ng/dL experience significant symptoms. Free testosterone (the bioavailable fraction) can also be low even when total T appears normal. Our providers evaluate both, alongside your specific symptoms, before making any recommendation.

Common symptoms include: persistent fatigue and low energy despite adequate sleep, reduced libido and erectile dysfunction, brain fog and difficulty concentrating, loss of muscle mass and increased body fat (especially visceral), mood changes (irritability, low motivation, depression), and reduced bone density. Not all symptoms occur in every patient. Many men present with just two or three. The consultation maps your specific symptom picture to the lab findings.

Yes. Exogenous testosterone suppresses the body’s natural LH and FSH production, which drives sperm production. Sperm counts typically drop significantly during TRT. If you are trying to conceive or plan to in the near future, TRT is not the right choice. Our providers can discuss alternative protocols that support testosterone levels while preserving fertility, such as clomiphene citrate, enclomiphene, or HCG, during your free consultation. See our fertility-friendly TRT page for a full breakdown of each option.

TRT is not appropriate for men who are actively trying to conceive, have untreated or elevated PSA suggesting prostate cancer, have a history of hormone-sensitive cancers, have severe untreated sleep apnea, have significantly elevated hematocrit, or have uncontrolled heart failure. These are not absolute exclusions in every case. Our providers conduct a thorough risk assessment at every consultation before recommending treatment.

There is no single best option. It depends on your schedule, lifestyle, and clinical profile. Injections (weekly testosterone cypionate) offer the highest dose flexibility, are the most studied, and are available via telehealth. Gels and creams provide stable daily levels without needles and are also telehealth-eligible. Pellets last 3-6 months with no ongoing maintenance but require an in-person insertion procedure at our Sugar Hill, GA clinic. Our providers will recommend based on your preferences and how your body is likely to respond. Full delivery method details are covered on the TRT program page.

Starting doses are conservative, typically 100-200mg of testosterone cypionate per week for injections, or equivalent for other delivery methods. The goal is to bring you into the mid-to-upper-normal physiological range (typically 600-900 ng/dL total testosterone), not to exceed normal range. Our providers adjust dose based on your 6-8 week follow-up labs and how you’re feeling. Most patients require at least one dose adjustment before reaching their optimal protocol.

Aromatization is the conversion of testosterone to estradiol by the enzyme aromatase. Some estradiol is normal and necessary. Men need estrogen for bone density, cardiovascular health, libido, and mood. The problem occurs when conversion is excessive, leading to symptoms like water retention, mood swings, and gynecomastia. Not all TRT patients need an aromatase inhibitor. Our providers monitor estradiol at every follow-up and only adds an AI when labs and symptoms indicate elevated estrogen, not as a routine add-on.

TRT suppresses your body’s natural testosterone production. If you stop, your levels will return to your pre-treatment baseline, or lower temporarily. Some patients choose to cycle off using a restart protocol (HCG plus clomiphene). Most long-term TRT patients choose to continue because the quality-of-life improvement is significant and well-tolerated. This is a conversation our providers have openly with every patient.

Most patients notice mood and sleep improvements within 1-3 weeks. Energy and libido improvements typically become consistent by weeks 3-6. Body composition changes require months 2-4 in combination with training and adequate protein intake. Full stabilization of all benefits typically occurs at months 4-6. Not everyone follows this exact timeline. Some patients feel a significant difference within weeks; others need more time and dose optimization.

When ED is driven by low testosterone, TRT often improves it significantly. However, ED has multiple causes, vascular, neurological, psychological, and hormonal. TRT addresses the hormonal component. If your testosterone is genuinely low and ED is a symptom, you should see meaningful improvement within 6-12 weeks of reaching therapeutic levels. If ED persists after levels are optimized, our providers will discuss whether additional evaluation or treatment is warranted. See our men’s sexual health page for the full range of ED treatment options.

Yes, but it is not a substitute for effort. TRT restores the hormonal environment that makes muscle building and fat loss possible. It won’t produce significant changes without resistance training and adequate protein intake. When those elements are in place, patients on TRT respond to training more effectively, recover faster, and see body composition changes that stalled before treatment. See the full picture on our TRT benefits page.

Comprehensive baseline panel including: total and free testosterone (two separate morning draws), estradiol, LH, FSH, SHBG, hematocrit and CBC, comprehensive metabolic panel, lipid panel, PSA (for patients 40 and over), and thyroid (TSH). This establishes your clinical baseline and confirms diagnosis before any prescription is written.

Follow-up labs at 6-8 weeks after starting, then quarterly once your protocol is stable. Labs include testosterone levels (to confirm therapeutic range), estradiol (to manage aromatization), hematocrit (TRT can raise red blood cell count and requires monitoring to prevent polycythemia), and PSA for patients 40 and over. This level of monitoring is what separates responsible clinical TRT from online clinics that skip labs entirely.

TRT stimulates red blood cell production, which can raise hematocrit. If it approaches 52-54%, Dr. Ashar will adjust, typically by reducing dose, switching delivery method (gels cause less hematocrit elevation than injections), or recommending therapeutic phlebotomy. This is a well-understood and manageable side effect when monitored properly. Elevated hematocrit that goes unmonitored increases clotting risk, which is why regular labs are non-negotiable on this program.

This is one of the most common concerns and the evidence does not support it. The saturation model of prostate biology suggests that once androgen receptors are saturated (which occurs at relatively low testosterone levels), additional testosterone does not stimulate additional prostate growth. Multiple large studies and meta-analyses have not shown an association between TRT and increased prostate cancer incidence. Our providers monitor PSA at baseline and on follow-up labs. Elevated PSA prompts urological evaluation before and during treatment.

TRT can accelerate androgenetic alopecia (male pattern baldness) in men who are genetically predisposed to it. If you have no family history of significant hair loss, TRT is unlikely to cause it. If you are already experiencing pattern hair loss, TRT may accelerate the timeline. This is a real consideration our providers discuss at your consultation. Options like topical finasteride can be added alongside TRT for patients who are concerned. Learn more on our hair restoration page.

TRT can worsen pre-existing obstructive sleep apnea in some patients. It does not typically cause sleep apnea in patients who don’t already have it. If you have known sleep apnea, our providers will review its severity and treatment status before prescribing. Untreated severe sleep apnea is a relative contraindication. Patients on CPAP who are well-controlled can generally proceed safely.

The cardiovascular evidence for TRT has evolved significantly. The 2023 TRAVERSE trial (Lincoff et al., NEJM), the largest prospective cardiovascular outcomes trial for TRT, found no increase in major adverse cardiovascular events in men with hypogonadism and pre-existing cardiovascular risk factors. Earlier concerns from observational studies were largely contradicted by better-designed research. The most significant cardiovascular risk from TRT is elevated hematocrit, which is why monitoring is required. Our providers review your full cardiovascular history at every consultation.

Yes, for Georgia patients. TRT injections, gels, and creams are fully managed via telehealth within Georgia. Testosterone pellets require an in-person visit to our Sugar Hill, GA clinic regardless of location. Labs are ordered at your nearest Quest or Labcorp. Note: if you are outside Georgia, we prescribe ED medications (sildenafil, tadalafil, PT-141) via telehealth in most states: see our sexual health page for details.

Tactus Health is a direct-pay practice. We don’t bill insurance. Pricing is transparent, you know exactly what you’re paying before committing to anything. HSA and FSA are accepted. Financing is available through CareCredit, Cherry, and AfterPay. The cost of TRT at a direct-pay clinic is often comparable to or less than insurance co-pays plus deductibles at a standard clinic.

The free consultation is your first step. Our providers order labs same day and most results are available within 48-72 hours. Once labs confirm low T and your consultation is complete, a prescription is written. Medication ships to your door within 5-7 business days. Most patients have their first dose within 2 weeks of their initial consultation.
