ENHANCED FORMULA
Advanced supplements
Here’s how Numan’s High Strength Testosterone Supplement differs from our standard supplement.
Optimised herbal extracts
Contains 12 times the amount of fenugreek extract than the standard supplement, with 50% fenuside. This makes it similar in quality to some of the top branded extracts.
Supports nutritional status
Formulated with 50% more zinc, crucial for maintaining normal male fertility and reproductive health whilst providing three times the vitamin D to support regular muscle function and bone health.
What’s in High Strength Testosterone Supplement?
Fenugreek Extract 600mg
Fenugreek extract is derived from the seeds of the fenugreek plant. At a dosage of 600mg, it’s been studied for its potential to naturally increase testosterone levels.
D-Aspartic Acid 3000mg
D-Aspartic Acid is an amino acid that plays a role in the production and release of hormones in the body. At a dosage of 3000mg, it’s believed to stimulate the release of a hormone in the brain that leads to the production of testosterone. Some studies suggest this could potentially increase testosterone levels, particularly in individuals with low levels or impaired sexual function.
Magnesium 250mg
Magnesium is an essential mineral that plays a role in over 300 biochemical reactions in the body, including the synthesis of testosterone. Some studies suggest a dosage of 250mg can help optimise testosterone levels, especially when combined with regular exercise. Magnesium also supports muscle and nerve function, energy production, and bone health.
Zinc 15mg
Zinc is a critical mineral for male fertility and testosterone production. With a dosage of 15mg, it plays a vital role in hormone production, including testosterone.
Copper 1mg
Copper, while not directly linked to testosterone production, is a key mineral that plays a role in nerve, bone, and immune system health.
Vitamin D3 600IU
Vitamin D3 is synthesised in the skin in response to sunlight and can also be consumed through supplements. It’s been associated with bone health and immune function especially in individuals with low baseline levels or limited sun exposure.

Key insights into your testosterone
What is testosterone?
Testosterone is a sex hormone that’s vital for men’s health. Produced in the testes, the hormone supports key male functions including sex drive, ability to get and maintain erections, fertility, muscle mass, and mood.
Why is testosterone important?
To ensure healthy bodily functions, you must have a certain level of the hormone. Lower levels of the hormone can, in some cases, impact libido, sexual function, energy, muscle mass, and mood.
How do I measure my testosterone levels?
You can assess your testosterone levels by taking a Testosterone Blood Test. It measures five key biomarkers to give you an accurate testosterone reading.
