Your symptoms start with biology. So does progress.
Restores physiological testosterone levels, supporting energy, focus, and mood stability.
Supports lean muscle mass and bone density through anabolic signaling.
Improves libido and sexual performance by restoring androgen signaling.
your complete care
Personalized TRT care starts with membership
Clinician guided male hormone therapy
Your clinician reviews your medical history and labs to determine eligibility and guide the right treatment choice for testosterone replacement or restoration.
HPG Axis Suppression
Exogenous testosterone bypasses the HPG axis, increasing circulating levels while suppressing LH and endogenous production. Most appropriate when natural output is already insufficient.
Androgen Signaling
Testosterone binds to androgen receptors throughout the body, regulating energy, libido, mood, muscle protein synthesis, and overall vitality.
Muscle & Bone Anabolism
Adequate testosterone supports lean muscle maintenance, strength, and bone density by promoting anabolic signaling in muscle and skeletal tissue.
Neurotransmitter Regulation
Testosterone influences dopamine and serotonin signaling, supporting motivation, focus, emotional regulation, and mental clarity.
Metabolic Signaling
Testosterone plays a role in insulin sensitivity and fat distribution, helping support healthier body composition and metabolic function.
Erythropoiesis & Oxygen Delivery
Testosterone stimulates red blood cell production, supporting oxygen delivery, stamina, and exercise capacity — which is why hematocrit is routinely monitored during therapy.

Frequently asked questions
Testosterone replacement therapy (TRT) is for men diagnosed with low testosterone based on blood testing and clinical symptoms. Candidates typically have below-normal testosterone levels along with symptoms such as low energy, reduced sex drive, erectile dysfunction, low mood, brain fog, or loss of muscle mass. A diagnosis requires appropriate lab testing and evaluation by a licensed provider.
TRT is not recommended for men who are actively trying to conceive or who wish to preserve fertility, as testosterone injections can suppress the body’s natural hormone signaling and reduce sperm production. In those situations, alternative treatment options may be more appropriate and can be discussed with a clinician.
Many men experience improved energy, motivation, and overall vitality after starting TRT. Common benefits include increased libido and sexual function, improved mood and mental clarity, and gains in lean muscle mass and strength. Over time, testosterone therapy may also support healthier body composition, metabolic function, and bone density. Individual results vary and develop gradually.
Results from testosterone replacement therapy typically occur in phases rather than all at once. Some men notice improvements in energy, mood, and libido within the first 1–2 weeks. Sexual function and fatigue often improve within the first month. Changes in muscle mass, fat distribution, and physical performance usually develop over several months, while bone density changes occur with longer-term treatment.
Testosterone cypionate is most commonly given as a subcutaneous injection, usually twice weekly, to maintain stable testosterone levels. Injections are typically done on consistent days each week. Dosing is individualized and adjusted over time based on lab results, symptoms, and clinical response. TRT is generally intended as a long-term therapy.
Yes. Comprehensive lab testing is required before starting testosterone replacement therapy and continues throughout care. Before treatment begins, we assess testosterone alongside related hormones and key health markers to confirm eligibility and establish an accurate baseline.
During treatment, labs are repeated at regular intervals to guide dosing and monitor how testosterone therapy is affecting multiple systems in the body. In addition to testosterone levels, this includes markers related to blood counts, prostate health, metabolic function, and cardiovascular risk. This broader lab view allows clinicians to adjust treatment as needed and maintain safe, effective therapy over time.
At Healthspan, lab monitoring is a core part of membership and is designed to support long-term outcomes, not just short-term symptom relief.
Testosterone replacement therapy is generally well tolerated when appropriately prescribed and monitored. Some men experience mild side effects, such as acne, oily skin, mood changes, fluid retention, headache, or injection-site irritation. These effects are often dose-related and can usually be improved by adjusting the dose or injection schedule.
Less commonly, TRT may be associated with more serious risks, including elevated red blood cell counts (hematocrit), changes in cholesterol levels, blood clots, or prostate-related concerns, particularly in men with underlying risk factors. Because testosterone affects multiple systems in the body, regular lab monitoring and clinical follow-ups are essential to maintain safe testosterone levels and identify potential issues early.
At Healthspan, lab testing and ongoing oversight are a required part of care to help ensure treatment remains safe, effective, and appropriate over time.
TRT is typically considered a long-term treatment. If therapy is discontinued, testosterone levels and related symptoms often return to baseline. Treatment plans are reviewed regularly, with comprehensive reassessment at least once per year.
Testosterone injections are prescribed as part of Healthspan membership, which provides the clinical and lifestyle support required for safe, effective testosterone replacement therapy. Medication is billed separately based on eligibility, while pricing remains consistent regardless of dose.
Membership covers baseline hormone testing, regular follow-up labs, and clinician-guided dose management, along with access to coaching and lifestyle support focused on nutrition, exercise, sleep, and recovery. This combined approach helps ensure testosterone therapy is managed as ongoing care — supporting both symptom improvement and long-term health.
