What is testosterone replacement therapy (TRT)?

TRT is a prescribed medical treatment that restores testosterone to normal physiological levels in men diagnosed with hypogonadism (clinically low testosterone). It's administered through injections, gels, patches, or pellets under ongoing medical supervision.

How do I know if I have low testosterone?

Symptoms like persistent fatigue, low libido, difficulty building muscle, weight gain, brain fog, and mood changes may indicate low T — but the only way to confirm is through a blood test measuring total and free testosterone levels. A level below 300 ng/dL on two separate morning tests is the clinical threshold.

Is TRT safe?

Large-scale clinical trials including the TRAVERSE trial (5,246 men) found no increased risk of heart attack, stroke, or prostate cancer with properly monitored TRT. Like any medical treatment, it has potential side effects — most commonly elevated red blood cells — which are manageable with regular lab monitoring.

How long does it take for TRT to work?

Most men notice energy and mood improvements within 3-6 weeks. Sexual function typically improves within 3-6 weeks. Body composition changes (muscle gain, fat loss) become noticeable over 3-6 months. Full optimization usually occurs by 9-12 months.

Can I get TRT online?

Yes. Licensed telehealth providers can prescribe TRT after reviewing comprehensive lab work and conducting a virtual consultation. The process includes at-home lab testing, a provider appointment, and medication delivered to your door.

Does TRT affect fertility?

Yes — exogenous testosterone suppresses sperm production. This is usually reversible after stopping TRT, but recovery can take 6-12 months. If fertility is a concern, discuss alternatives like clomiphene or HCG co-therapy with your provider before starting.

How much does TRT cost?

Online TRT typically ranges from $99-199/month depending on the provider, medication type, and level of monitoring included. Lab work may cost $50-200 per panel. Heyday Health offers transparent, all-inclusive pricing.

What's the difference between TRT and steroids?

TRT restores testosterone to normal physiological levels (450-700 ng/dL) under medical supervision. Anabolic steroid use involves supraphysiological doses (often 2-10x normal levels) without medical oversight. The goals, doses, and risk profiles are fundamentally different.

Will I need to take TRT forever?

TRT is a long-term treatment. Because exogenous testosterone suppresses natural production, stopping treatment typically results in testosterone dropping back to — or below — pre-treatment levels. Some men choose to taper off under medical guidance, but most continue indefinitely.

What are GLP-1 medications and how do they relate to testosterone?

GLP-1 receptor agonists (semaglutide, tirzepatide) are medications that reduce appetite and promote significant weight loss. Since excess fat converts testosterone to estrogen, losing weight through GLP-1 therapy can help improve testosterone levels naturally. Some men benefit from combining GLP-1 with TRT for comprehensive metabolic optimization.
