👨‍⚕️ Doctor's Practical Tips

Evidence-based practical advice from experienced clinicians

1

Always confirm low testosterone with two morning blood tests before starting this medicine.

2

Inject into the buttock or thigh muscle, rotating sites to prevent irritation.

3

Monitor red blood cell count regularly; if it gets too high, dose adjustment or blood donation may be needed.

4

Check prostate-specific antigen (PSA) and perform a digital rectal exam before and during treatment.

5

Ask about sleep apnoea symptoms at every visit, especially if the patient snores or feels sleepy during the day.

6

Discuss fertility plans before starting, as this medicine can suppress sperm production.

7

Monitor blood pressure and watch for fluid retention, especially in older men or those with heart disease.

8

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is injected into a muscle, so it bypasses the stomach and liver first-pass metabolism. After injection, the testosterone ester is absorbed slowly from the muscle depot into the bloodstream. The rate of absorption depends on the type of ester and the injection site. For testosterone enanthate, peak blood levels are usually reached within 24 to 48 hours after injection. The absorption is not affected by food or stomach acid.

DistributionOnce in the bloodstream, testosterone is transported bound to proteins. About 98% of testosterone is bound to sex hormone-binding globulin and albumin. Only about 1-2% remains free and biologically active. Testosterone distributes widely into tissues such as muscle, bone, prostate, skin, liver, and brain. It crosses the blood-brain barrier and can also cross the placenta. The volume of distribution is not well established from the available information.

Protein BindingApproximately 98% of testosterone in the blood is bound to proteins, mainly sex hormone-binding globulin and albumin. Only about 1-2% is free and available to enter cells and exert effects.

MetabolismTestosterone is metabolized mainly in the liver. It is broken down by enzymes called 5-alpha-reductase and aromatase into active metabolites such as dihydrotestosterone and estradiol. The liver also converts testosterone into inactive metabolites through reduction and conjugation, which are then eliminated. Because this medicine is injected, it avoids the first-pass metabolism in the liver that occurs with oral testosterone, but the liver still processes the hormone once it is in the bloodstream.

Half-LifeThe elimination half-life of testosterone enanthate after intramuscular injection is approximately 4 to 5 days. However, the half-life can vary depending on the specific ester, the injection site, and individual factors. This prolonged half-life is why injections are usually given every 1 to 4 weeks.

ExcretionTestosterone and its metabolites are mainly excreted in the urine as conjugates, such as glucuronides and sulfates. A small amount is excreted in the feces. The exact proportions are not well established from the available information.

BioavailabilityThe bioavailability of this medicine after intramuscular injection is high because it bypasses the digestive system and liver first-pass metabolism. However, the exact bioavailability percentage is not well established from the available information.

Onset of ActionThe effects of this medicine on symptoms such as low libido and fatigue may begin within 2 to 4 weeks, but full benefits on muscle mass, bone density, and mood usually take 3 to 6 months of regular treatment. The onset can vary depending on the dose, the individual, and the severity of testosterone deficiency.

Peak Plasma TimeAfter an intramuscular injection of testosterone enanthate, peak plasma testosterone levels are usually reached within 24 to 48 hours. However, the peak can vary depending on the injection site and the individual.

Duration of ActionThe duration of action of this medicine depends on the ester and the dose. For testosterone enanthate, the effects usually last for about 2 to 4 weeks after a single injection. This is why injections are typically given every 1 to 4 weeks to maintain stable testosterone levels.

How It Works

This medicine delivers testosterone, which is the primary male sex hormone. Testosterone works by binding to androgen receptors inside target cells, including cells in the prostate, muscle, bone, and brain. Once bound, the receptor moves into the cell nucleus and changes the activity of specific genes. This leads to the development and maintenance of male sexual characteristics, increased muscle mass, bone strength, and red blood cell production. Testosterone can also be converted into dihydrotestosterone by the enzyme 5-alpha-reductase, which amplifies some effects on the prostate and skin, and into estradiol by the enzyme aromatase, which affects bone and breast tissue. In men with low testosterone, this medicine restores levels toward the normal range, which helps improve symptoms such as low libido, fatigue, and mood changes. The effects are not immediate and usually develop over several weeks to months of regular treatment.

Mechanism Steps

1

Injection and absorption: This medicine is injected into a muscle, where the testosterone ester is slowly absorbed into the bloodstream.

2

Ester cleavage: Once in the blood, enzymes called esterases remove the ester chain from testosterone, releasing free testosterone, which is the active form.

3

Binding to androgen receptors: Free testosterone enters target cells and binds to androgen receptors in the cytoplasm.

4

Gene activation: The testosterone-receptor complex moves into the nucleus and binds to specific DNA sequences, turning on or off genes that control male sexual development, muscle growth, bone strength, and red blood cell production.

5

Conversion to other hormones: In some tissues, testosterone is converted to dihydrotestosterone by 5-alpha-reductase or to estradiol by aromatase, which adds to its effects.

6

Negative feedback: Increased testosterone levels signal the pituitary gland to reduce production of luteinizing hormone and follicle-stimulating hormone, which can decrease natural testosterone production and sperm production.

Dosage Information

Adult Dosage	The dose of this medicine must be individualized by a qualified clinician based on the indication, age, weight, and clinical response. For testosterone replacement in adult males with hypogonadism, a common starting dose is 250 mg injected into the muscle every 2 to 4 weeks. Some clinicians may use a different schedule, such as 100 mg to 200 mg every 1 to 2 weeks. Your doctor will adjust the dose based on your blood testosterone levels and symptoms. Do not change the dose or frequency without consulting your doctor. This medicine is for intramuscular use only and should be injected by a healthcare professional.
Pediatric Dosage	Pediatric dosing is not established from available information. Consult a pediatrician or pediatric endocrinologist for any use in children or adolescents.
Elderly Dosage	Elderly men may be more sensitive to the effects of this medicine, especially fluid retention, prostate enlargement, and heart problems.
