Testosterone Replacement Therapy - Injections

Injectable TRT is a testosterone replacement therapy protocol that uses testosterone cypionate, which is commonly injected once up to three times per week, to help restore and increase testosterone levels in men diagnosed with low testosterone. It is designed for eligible men who want a provider-guided approach to improving symptoms associated with low testosterone.

TRT is an ongoing treatment and an investment in your long-term health. When your body has low testosterone, it does not suddenly begin producing optimal levels again on its own. For that reason, TRT is used to help maintain consistent, optimized hormone levels so you can feel your best every single day. Many patients report feeling their best when total testosterone levels are above 800 and free testosterone levels are above 200, though individual targets may vary based on your provider’s guidance.

Men who start TRT often report improvements in energy, motivation, libido, sexual performance, strength, recovery, mood, mental clarity, and overall quality of life after their testosterone levels are optimized. Results vary from person to person, and it can take up to 6 months to fine-tune a protocol and experience the full benefits of TRT.

This is one of the most common and important questions we hear. Many physicians are not hormone specialists, and the standard “normal” testosterone range used in most labs is extremely broad. It’s designed to identify severe deficiencies, not to determine whether your levels are truly optimal for how you feel and perform.

Because of this, it’s very possible to fall within the “normal” range and still experience symptoms like low energy, reduced libido, brain fog, poor recovery, and decreased motivation. In fact, many men begin noticing these symptoms when their testosterone levels drop below around 500, even though that level is still considered “normal” by most lab standards.

At LaSara, we focus on optimization, not just whether you fall inside a wide reference range. Your symptoms, lifestyle, goals, and overall health all matter. If you don’t feel like yourself, your hormone levels may not be where they need to be for you, even if they’re technically “normal.”

The cost is $169 per month. Your subscription includes your medication, treatment supplies when applicable, follow-up medical consults, routine labs every 2–6 months, complete program management, free shipping, and automatic refills. There are no surprise refill fees or hidden monitoring costs.

We typically recommend that patients administer two injections per week, commonly splitting this on a Monday and Thursday. Two injections per week helps maintain a consistent, elevated, and optimized level of testosterone in your body. While this is LaSara’s gold standard approach, some patients prefer to inject once per week, and others may inject three times per week or even daily. Your provider will work with you to determine the ideal protocol based on how you are responding to treatment.

Yes. Blood work is an essential part of safe and effective testosterone therapy. It helps identify whether you qualify for treatment, establishes your baseline hormone levels, and allows your provider to build a personalized protocol based on your specific needs. You can either complete labs through LaSara or upload qualifying recent results that were completed within the last six months and include, at a minimum, your total testosterone, free testosterone, a complete blood count, and total PSA.

LaSara treats men from their young 20s all the way into their 90s who are appropriate candidates for TRT. Age can be one factor that contributes to low testosterone, but it is not the deciding factor in whether TRT is right for a patient.

The more important question is whether a man has clinically diagnosed low testosterone, symptoms that align with low T, and lab results that support treatment. For men who have explored natural ways to increase testosterone—such as improving sleep, nutrition, exercise, weight management, and lifestyle habits—without success, TRT may become a strong option.

Your provider will review your labs, symptoms, health history, and goals to determine whether TRT is appropriate for you.

Low testosterone can affect many aspects of a man’s physical and mental performance. Common symptoms include low energy, reduced libido, erectile performance changes, brain fog, poor concentration, decreased motivation, loss of strength, reduced muscle mass, increased body fat, mood changes, poor sleep, and slower recovery from exercise. Blood work is the best way to determine whether low testosterone may be contributing to these symptoms.

TRT can reduce the body’s natural hormone signaling to the testes, which may decrease sperm production and affect fertility in some men. TRT does not automatically make every man infertile, but individual responses vary. If fertility, sperm production, or testicular function are important to you, discuss this with your provider before starting treatment.

Yes. TRT is an ongoing treatment. Your provider may adjust your dose, frequency, or supporting medications based on your lab results, symptoms, side effects, goals, and overall response to treatment.

LaSara is not a one-size-fits-all clinic. We fine-tune every patient’s protocol based on their labs, symptoms, goals, and response to treatment. While many providers take a cookie-cutter approach—glancing at your labs and prescribing a standard dose—we take the time to understand exactly what you want to achieve and build a protocol designed to get you there.

Our providers review your labs in detail, spend time understanding your performance goals, and work with you to safely push the limits of what TRT can do. We believe optimization is not about doing the minimum—it’s about doing it right, with precision, oversight, and intention.

Consistency is one of the most important factors in successful TRT, and we take that seriously. We make every effort to ensure you never receive your testosterone refill late, and we proactively provide lab reminders so you stay on track with your monitoring and progress. No gaps, no guesswork, no falling off protocol.

We do not believe in simply prescribing testosterone and sending patients on their way. Our providers stay engaged, monitor your progress, and make adjustments when clinically appropriate so you continue moving forward.

Whether your goal is to improve energy and wellness, build strength, enhance performance, or feel like the best version of yourself every day, LaSara is built to help you get there with a personalized, high-performance approach to TRT.
