Ingredients


Tongkat Ali


An Asian plant also known as Malaysian ginseng. It positively affects hormonal balance by increasing testosterone availability, libido levels and overall body performance. It has the effect of increasing strength and energy and supports the building of lean muscle mass. Improves sexual performance and fertility. Promotes well-being and relieves fatigue and stress.

Fadogia agrestis


A tropical plant from the marzanaceae family, native to Africa. There is as much as 1200 mg of it per serving in TESTOSTERONE 21. Fadogia Agrestus is an ingredient well-known in the industry for improving testosterone levels in the male body. Interestingly, the first positive effects can often be counted on after just five days of regular use of TESTOSTERONE 21. This ingredient raises the testosterone level in the blood and can also positively translate into recovery after intensive physical effort (including, for example, training at the gym). It increases libido and supports sexual performance.

Ashwagandha extract


An adaptogenic plant that reduces the destructive effects of stress. It supports the nervous and immune systems and reduces the feeling of fatigue. Properties that reduce the amount of cortisol in the body affect testosterone growth.

Zinc


This element is thought to strengthen the body’s overall immunity and improve academic performance. When used regularly, zinc can also alleviate the symptoms of osteoporosis and gastrointestinal diseases (including, for example, inflammatory bowel disease, haemorrhoids or ulcers).

Dosage


TESTOSTERONE 21 is a preparation that – when combined with a complete and balanced diet, regular exercise or healthy sleep – has a perfect effect on the body. It provides a beautiful energy boost, making us feel as if we are 21 years old again! Of course, the results will be visible with proper dosage, which is as follows: 2 tablets two times a day with meals. Optimal effectiveness should be felt within 1-3 weeks.

Need help?

Testosterone 21 is a high potency testosterone support formula from Hi-Tech Pharmaceuticals, supplied in 120 tablets with 30 servings per bottle. It combines FadogiaPure Fadogia Agrestis, TK100 Tongkat Ali extract and KSM-66 Ashwagandha.

The three headline ingredients are Fadogia Agrestis, dosed at 1200 mg per serving, Tongkat Ali as the TK100 extract, and KSM-66 Ashwagandha. Zinc is also included in the formula.

Fadogia Agrestis is a tropical African plant from the Rubiaceae family. It is well known in the industry for its effect on testosterone levels in men and is also linked to better recovery after intensive training and to libido and sexual performance.

Testosterone 21 provides 1200 mg of Fadogia Agrestis per serving, which is what puts it in the high dose rather than the token dose category.

Tongkat Ali, also called Malaysian ginseng, supports hormonal balance by improving testosterone availability and libido. It is also associated with more strength and energy, lean muscle mass, better wellbeing and less fatigue.

Ashwagandha is an adaptogen that reduces the destructive effects of stress, supports the nervous and immune systems and cuts the feeling of fatigue. Because it lowers cortisol, it works indirectly in favour of testosterone.

Cyclosome is Hi-Tech’s own delivery system. It is used in Testosterone 21 to maximise how well the ingredients are utilised by the body rather than simply increasing the raw amount on the label.

Many boosters hide behind proprietary blends with underdosed ingredients. Testosterone 21 instead states substantial amounts of premium standardised extracts, which is why the Fadogia dose is spelled out rather than buried in a blend.

The recommended dose is two tablets twice daily with meals.

Optimal effectiveness should be felt within one to three weeks, and it works best alongside a complete and balanced diet, regular training and healthy sleep.
