Lay the foundations for your hormonal health

Using the Tasso+ device, this at-home test measures four key biomarkers to detect early signs of testosterone deficiency–quickly and conveniently. It lays the groundwork for deeper insight by your doctor.

Total Testosterone

Total testosterone reflects the combined levels of both free and protein-bound testosterone present in the bloodstream. Free testosterone, which constitutes only a small fraction of the total, is unbound and biologically active.

Free Testosterone

Free testosterone refers to the fraction of testosterone in the blood that is not bound to sex hormone-binding globulin (SHBG) or albumin. This free portion is what your body can immediately use for its various functions.

Albumin

Albumin is a protein made by the liver and is essential for maintaining oncotic pressure (fluid balance in blood vessels) and transporting substances like hormones (including testosterone), fatty acids, and medications through the bloodstream.

SHBG

Sex Hormone-Binding Globulin (SHBG) is a glycoprotein produced primarily by the liver. It binds to sex hormones - mainly testosterone and estradiol - and transports them through the bloodstream. By binding these hormones, SHBG regulates their access to tissues and influences how much of each hormone is bioavailable.

How do I take this test?

1. Take the test at home.

Use the Tasso+ device to collect a small blood sample before 11am when testosterone is naturally highest. Please refer to our Instruction Manual for the exact steps.

2. Post your sample.

Place your sample in the prepaid pack and post it to our certified lab for testing.

3. View your results.

Get access to your results online within days. Our doctors will advise the next steps to assess if low-T treatment is right for you.

Low testosterone explained

What is Low Testosterone?

Testosterone levels decline naturally as you get older but for the first time in medical history, lifestyle factors are catching up with age as a risk factor. If testosterone levels drop too low, it can cause symptoms such as low libido, brain fog, loss of muscle mass, depression and more. The formal name for low T is hypogonadism.

What is Testosterone Replacement Therapy (TRT)?

TRT helps to restore healthy testosterone levels for male vitality, body function and longevity. Maintaining them helps to promote muscle mass, sexual function, metabolic health, cognitive function and more.

Men’s health is broken. We’re here to fix it.

Prof. Suks Minhas

MD FRCS Urol

"As a Consultant Urologist and Andrologist, my mission is to provide world-class, evidence-based care across the full spectrum of men’s health—encompassing sexual function, fertility, low testosterone, hormonal health, and urological wellbeing. Every man deserves access to expert, compassionate care regardless of background, ethnicity, or socioeconomic status. Equitable healthcare is not just an ideal—it is a responsibility."

Dr. Ian Gallen

Endocrinologist & Medicine Advisor

"In the UK, we know that men are disproportionately less likely to seek medical help for various reasons, not least when it comes to conditions that may seem to carry a stigma. Heracles wants to break that cycle not just through treatment, but by equipping men with the knowledge and confidence to own their health and to thrive inside out."

Dr. Richie Kirwan

PhD Nutritionist

"Our modern food environment, our activity levels and the way we live our lives simply do not lead us towards health. My goal at Heracles is to help educate and guide men towards healthier food, movement and lifestyle habits that will lead them to the state of optimal health and function that they deserve, and that will help them live a longer, healthier, more fulfilling life."

FAQs & Common Concerns

Low testosterone (testosterone deficiency) also known as hypogonadism in men occurs when the body is unable to make enough testosterone. Low testosterone can significantly affect a man's health and quality of life.
The symptoms of low testosterone vary depending on when you develop it. In adult males, the most common symptoms include: erectile dysfunction, decreased sex drive, difficulty concentrating, decrease in muscle mass, low mood and more.
Low testosterone is diagnosed by a combination of medical history and symptoms review, blood tests and a physical where appropriate. The best place to start is with an initial Testosterone Blood Test and your doctor will take it from there.
Low testosterone is relatively common, especially as men age. A European study found that testosterone deficiency affected about 2 in 100 men aged 40 to 79 years and about 5 in 100 men aged 70 to 79 years. It is also more common in men who are overweight and men who are in poor general health with long-term health conditions.
TRT directly raises testosterone levels to the normal physiological range and relieves symptoms like fatigue, low libido, ED, depression, and muscle loss. Common forms of TRT include injectables, gels, creams, patches and implants.
No, you cannot take standard TRT if you are trying to conceive because it can drastically lower sperm production, even within a few weeks. Contact our medical team to discuss further. You may be able to try clomid or hCG treatment for low testosterone that preserves your fertility. Check out our guide to fertility-friendly low T treatment here.
The combination of TRT with hCG in men is not strongly evidence-based, despite a physiological rationale. While hCG mimics luteinizing hormone (LH) and may help maintain intratesticular testosterone and spermatogenesis during TRT, the clinical evidence supporting this approach is limited. Most studies are small, short-term, and observational, lacking the rigor of large randomized controlled trials needed to confirm efficacy and safety. Moreover, individual responses to hCG vary widely, and there is little long-term data on potential risks such as increased estradiol levels or overstimulation of the testes. As a result, the use of hCG alongside TRT remains a clinician-guided decision rather than a standard, well-supported medical practice.
TRT is generally safe for men with medically confirmed low testosterone when prescribed and monitored properly by a specialist. However, like any long-term hormonal therapy, it comes with risks and side effects that must be balanced against the benefits. Please consult with one of our specialists who will be able to conduct a thorough review of your suitability for TRT.
Yes! Testosterone deficiency is a hormonal condition that requires medical diagnosis and treatment. Our doctors are experts in low testosterone, fully licensed with decades of clinical experience between them.
When under medical supervision and with the appropriate protocols in place, yes. This is exactly what we do here at Heracles.
