PHYSTA is a patented, standardised, freeze-dried water extract of Eurycoma longifolia root, developed and produced by Biotropics Malaysia and standardised to consistent levels of its active compounds (eurycomanone, glycosaponins, polysaccharides, protein). "Standardised" means every capsule delivers a controlled, measured dose, unlike generic Tongkat Ali powders, whose active content varies widely.

Because active compound levels in raw Tongkat Ali vary enormously by source, soil, root age and processing. A standardised extract like PHYSTA guarantees the same clinically studied dose every time, which is why the clinical results were achieved with PHYSTA specifically, at a defined 200mg dose. Consistency is the difference between a studied product and guesswork.

Natural support is gradual, not an overnight spike. In clinical studies, measurable improvements in hormone profile, mood and quality-of-life scores were seen over 4 to 12 weeks of daily use. Give it several weeks of consistent daily intake.

Neither a synthetic booster nor replacement. Nu-Prep supports your body's OWN testosterone naturally, helping restore it within a healthy range. It does not introduce external hormones the way replacement therapy (TRT) does, and it does not artificially push levels above the natural range the way anabolic steroids do.

In the published human trials, standardised PHYSTA was well tolerated, with safety profiles comparable to placebo and no serious adverse effects reported at the studied doses. Toxicity studies in animals also supported its safety. As with any supplement, if you have a medical condition, take medication, or have hormone-sensitive conditions, consult your doctor or pharmacist first.

Yes. Chronic stress raises cortisol, which works against testosterone. In a randomised, double-blind, placebo-controlled trial of 63 moderately stressed adults, 200mg/day of standardised Tongkat Ali for 4 weeks reduced cortisol exposure by 16%, raised testosterone status by 37%, improved the cortisol-to-testosterone ratio by 36%, and significantly reduced tension (-11%), anger (-12%) and confusion (-15%).

Clinical evidence supports it. In a 12-week randomised, double-blind, placebo-controlled study of men, standardised PHYSTA extract significantly improved sexual wellbeing and quality-of-life measures versus placebo, using validated tools (IIEF, SF-36). Tongkat Ali has a long traditional use for male vitality, and modern trials support these effects.

A 6-month randomised, double-blind, placebo-controlled trial in men with androgen deficiency of the ageing male (ADAM) found that 200mg/day of Eurycoma longifolia significantly improved erectile function (IIEF-5), with the greatest gains when combined with regular exercise. Testosterone increased in nearly half of participants.

Standardised Tongkat Ali has been associated with reduced fatigue and improved physical function. In the ageing-male PHYSTA trial, the extract significantly improved the Physical Functioning domain of quality of life versus placebo. Pilot work in older, physically active adults reported increases in testosterone and muscular force.

Primarily men from around 30 onward who feel their drive, energy, strength or edge slipping, and who want a natural, clinically studied way to support their own testosterone, rather than a synthetic hormone or an untested product. The clinical trials were conducted largely in men in the 30-70 age range.

Some PHYSTA studies included women (the stress-hormone trial studied 32 men and 31 women), and a separate study reported improved menopausal quality of life and mood with Physta 100mg. However, Nu-Prep Tongkat Ali 200mg is positioned and formulated for men. Women should consult a healthcare professional before use.

If you take prescription medication, have a chronic condition, or are under medical care, speak to your doctor or pharmacist before starting, as with any supplement. Tongkat Ali is generally well tolerated, but individual circumstances vary and a pharmacist can advise on your specific situation.

One 200mg capsule daily, taken consistently, matching the dose and regimen used in the clinical studies. Because natural testosterone support is gradual, the benefit builds over weeks of daily use and is best maintained by continued daily intake, restore, then hold it.
