6 x Testosterone Undecanoate 40mg x 10 Capsules Classification
Testosterone Undecanoate belongs to the family of androgens and anabolic steroids (AAS). It is a synthetic derivative of testosterone, designed to supplement or restore natural testosterone levels in the body. In classification terms, it falls under:
- Pharmaceutical Class: Androgen and anabolic steroid
- Form: Oral capsule (soft gel capsule for precise absorption)
- Strength: 40mg per capsule
- Pack Size: 6 blister packs, each containing 10 capsules
- Primary Function: Testosterone replacement therapy (TRT)
This classification is important for patients and fitness enthusiasts alike, as it helps them understand where the medication fits in the treatment of male hypogonadism and other testosterone-related deficiencies. Testosterone Undecanoate differs from injectable testosterone esters because of its oral format, making it more convenient and discreet.
Unlike many oral steroids that may cause liver strain, Testosterone Undecanoate is absorbed via the lymphatic system, reducing the direct burden on the liver. This classification makes it safer compared to harsher oral anabolic agents, and it is frequently prescribed in the UK for restoring physiological testosterone levels.
What is 6 x Testosterone Undecanoate 40mg x 10 Capsules?
6 x Testosterone Undecanoate 40mg refers to a prescribed oral testosterone replacement therapy (TRT) that comes in capsule form. Each capsule contains 40mg of Testosterone Undecanoate, a long‑acting testosterone ester designed for slow and steady release once metabolised.
The product is specifically created to treat men who suffer from clinically diagnosed testosterone deficiency, known as hypogonadism. Such deficiencies can cause:
- Low libido and erectile dysfunction
- Fatigue and low energy levels
- Loss of muscle mass and strength
- Increased fat retention, especially around the waist
- Depressed mood, irritability, and poor mental focus
- Decreased bone density and risk of osteoporosis
This packaging of 6 x 10 blister packs ensures a course suitable for monitoring and adjusting dosages under medical supervision. For many UK patients and athletes using TRT, the convenience of oral capsules over injectables provides an easier method of hormone regulation.
Recommended Dosage for Testosterone Undecanoate 40mg
The recommended dosage of Testosterone Undecanoate 40mg must always be determined by a healthcare professional. Standard guidance usually prescribes:
- Starting Dose: 120–160mg daily (3–4 capsules), split across two doses, taken with meals.
- Maintenance Dose: 40–120mg daily (1–3 capsules), adjusted according to blood testosterone levels and clinical response.
- Long-Term Management: Some individuals may require lifelong supplementation, though dosages may reduce once steady hormone balance is achieved.
It is vital that capsules are taken with meals containing fat, as dietary fat significantly improves absorption via the lymphatic route. Skipping meals or taking Testosterone Undecanoate on an empty stomach reduces bioavailability.
Important guidelines to follow:
- Capsules should be swallowed whole, not chewed or broken.
- Dosage timing should be consistent (morning and evening are common).
- Medical check-ups should be scheduled every 3–6 months for hormone evaluation.
- Never exceed prescribed limits — overuse can lead to adverse cardiovascular and hormonal effects.
Taking this product responsibly ensures that testosterone is restored to natural physiological levels rather than reaching an excessive, performance-enhancing dose.
How Does Testosterone Undecanoate 40mg Work?
Testosterone Undecanoate works by providing the body with a stable supply of exogenous testosterone. Unlike short-acting testosterone esters, it has a unique structure:
- Conversion in the Body:
After oral absorption, Testosterone Undecanoate bypasses the immediate liver metabolism and enters the lymphatic system. From there, it circulates in the bloodstream and slowly converts into free testosterone. - Hormonal Restoration:
The primary function is restoring testosterone to a normal male physiological range, counteracting clinical symptoms of deficiency. - Target Organ Effects:
- Muscles: Stimulates protein synthesis, aiding muscle growth and repair.
- Bones: Prevents bone loss, strengthening skeletal density.
- Brain: Improves mood, focus, and libido via central nervous system pathways.
- Blood: Stimulates red blood cell production, increasing vitality and energy.
This controlled release mechanism ensures smoother testosterone levels, avoiding sharp hormonal spikes common with injectable esters.

When should you take Testosterone Undecanoate 40mg
Timing is essential for maximising effectiveness. The key recommendations are:
- Morning and Evening: Capsules are best taken twice daily to maintain stable blood testosterone levels.
- With Food: Always take it after a meal that contains fat to optimise absorption.
- Consistency: It’s important to take at the same time each day for steady hormone release.
- During Long-Term Therapy: Continue for the full prescribed duration — usually months to years, depending on your health condition and doctor’s advice.
Proper administration ensures the treatment works effectively, minimising risks of uneven hormone fluctuations.
When Should You Not Take Testosterone Undecanoate 40mg
Testosterone therapy is not suitable for everyone. Avoid taking this product if:

What is the Mechanism of Testosterone Undecanoate 40mg
The unique mechanism of Testosterone Undecanoate distinguishes it from other forms:
- Absorption Pathway: Unlike many oral drugs that go directly to the liver, Testosterone Undecanoate enters the lymphatic system when taken with dietary fat.
- Conversion: Once in circulation, the undecanoate ester is gradually cleaved, releasing free testosterone slowly into the bloodstream.
- Action Sites: Testosterone binds to androgen receptors in muscle, bone, skin, and brain, initiating anabolic and androgenic effects.
- Stability Advantage: Avoids sharp hormonal peaks, making it a better therapeutic option for long-term testosterone replacement.
