Testolido 250 (4ml) Injection

Overview About Testolido 250 (4ml) Injection

Testolido 250 (4ml) Injection is a prescription testosterone medicine designed for testosterone replacement therapy when a man has hypogonadism that’s confirmed by symptoms plus low lab values.

This product is commonly understood as testosterone undecanoate 250 mg/mL in a 4 mL presentation (total 1000 mg/4 mL), similar in concept to other long-acting testosterone undecanoate injections.

If your carton or label lists a different concentration, follow the label and your prescriber’s directions.

What it’s used for

How it works

Testosterone is the main male sex hormone. When levels are low, replacing testosterone can help improve symptoms and support functions like sexual health, bone density, red blood cell production, and body composition.

Long-acting options are often chosen by people who prefer fewer injections and steadier levels over time, compared with shorter-acting testosterone shots.

How it’s given

This medication is given by deep intramuscular injection, typically into the gluteal muscle, and the injection is usually done slowly by a trained professional. The exact dosing schedule depends on your diagnosis, lab results, response, and side effects.

Many long-acting testosterone undecanoate regimens use a loading phase and then maintenance doses spaced weeks apart, but your prescriber should individualise this.

Important safety information to know

Testosterone therapy is not a casual medication, and it’s worth taking the risks seriously.

• Do not use in pregnancy. Testosterone can harm an unborn baby.
• Prostate and breast cancer risk: Men with known or suspected prostate cancer or male breast cancer should not use testosterone. Testosterone can worsen certain prostate conditions, so screening and symptom review matter.
• Blood thickening (high hematocrit): Testosterone can increase red blood cells, which may raise clot risk in some people.
• Heart and stroke risk: Research has shown mixed results. If you already have heart disease, high blood pressure, high cholesterol, sleep apnea, diabetes, or you smoke, your clinician may monitor you more closely.
• Swelling and fluid retention: Can be more noticeable in people with heart, kidney, or liver problems.
• Mood and sleep: Some people report acne, irritability, or changes in sleep. Sleep apnea can worsen in some patients.
• Fertility: Testosterone therapy can reduce sperm production and may impact fertility. If having children is a near-term goal, ask about fertility-preserving alternatives.

FAQs About Testolido 250

How should I store Testolido 250 (4ml) Injection?

Store it at controlled room temperature and protect it from excessive heat and light. Do not freeze. Always follow the storage instructions on the product carton or pharmacy label.

Is testosterone a controlled substance?

Yes. In the U.S., testosterone products are generally Schedule III controlled substances, meaning refills and dispensing are regulated.

What if my next dose is late by a week or two?

Do not double up. Contact your prescriber to safely reset the schedule. With long-acting injections, timing matters, but the safest adjustment is individualised.

Can I travel with my testosterone medication and supplies?

Usually yes, but carry it in the original packaging with the prescription label. For flights, keep it in your carry-on if possible and allow extra time for screening.

Will testosterone therapy affect PSA testing or other lab results?

It can. Testosterone may influence PSA, hematocrit/haemoglobin, and lipid values. Tell your clinician you are using testosterone before lab work so results are interpreted correctly.
