From Traditional Remedy to Evidence-Based Health Solution

Introduction: The Question Everyone Asks

When you hear about a supplement backed by 26 clinical studies, one question naturally arises: "Is it safe & does it actually work?"

For Nu‑Prep Tongkat Ali, powered by the patented PHYSTA® extract the answer lies in a growing body of peer-reviewed research that spans immunity, hormonal health, stress reduction & sexual well-being. But science isn't just about listing benefits. It's about understanding the full picture including the safety considerations that responsible consumers deserve to know.

Let's walk through what 26 clinical studies actually tell us

Part I: What the Studies Say. The Efficacy Evidence

 

Testosterone & Vitality in Aging Men

 

A landmark 2021 multicenter, randomized, double-blind, placebo-controlled trial followed 105 men aged 50–70 with testosterone levels below 300 ng/dL. Participants received either 100mg, 200mg of PHYSTA®, or a placebo daily for 12 weeks .

 

The results were remarkable:

 

·       The 200mg group showed significant testosterone increases at weeks 2, 4, 8 & 12 — meaning benefits were visible within just two weeks .

·       Both PHYSTA® groups experienced significant reductions in Ageing Male Symptoms (AMS) & Fatigue Severity Scale scores .

·       DHEA levels increased, while cortisol (the stress hormone) decreased significantly in the 200mg group .

 

This study confirmed what traditional use had long suggested: Tongkat Ali, when properly standardized, can meaningfully support hormonal health in aging populations.

 

Immunity: A Surprising Breakthrough

One of the most intriguing studies focused not on testosterone, but on immune function. In a 4-week randomized trial involving 84 middle-aged Japanese participants, those taking 200mg of PHYSTA® daily showed significantly higher "Scoring of Immunological Vigor" (SIV) scores compared to placebo .

 

The active group saw increases in:

 

·        Total T cells

·       Naïve T cells

·       CD4+ T cells

 

This suggests that Tongkat Ali may enhance comprehensive immunity in both middle-aged men & women a finding with global relevance as populations age worldwide .

 

Stress, Mood & Quality of Life

A 24-week study of 93 moderately stressed participants examined PHYSTA® combined with multivitamins. While between-group differences weren't always significant, within-group improvements were notable :

 

·       Emotional well-being improved significantly (P < 0.001)

·        Social functioning and vitality showed marked improvement

·        Physical stress decreased by 15% in the active group versus just 0.7% in placebo

·        Lymphocytes increased significantly in the active group

 

Sexual Performance & Well-Being

A 2014 study on 30 men aged 40–65 evaluated a combination of PHYSTA® and Polygonum minus over 12 weeks. Results showed significant improvements in :

·        Sexual Intercourse Attempt diary scores

·        Erection Hardness Scale

·        Sexual Health Inventory of Men

·        Aging Male Symptom scale

 

All improvements were statistically significant (P < 0.05) & the product was well tolerated with no adverse events attributed to the study product.

 

Part II: What Science Says About Safety

 

With efficacy established, the safety question becomes paramount. Here's what the evidence reveals.

 

The Good News: Short-Term Studies Show Favorable Safety

 

Across multiple clinical trials, PHYSTA® has demonstrated a favorable safety profile. The 2021 testosterone study, for instance, reported no safety-related clinically relevant changes in:

·        Complete blood count

·        Lipid profile

·        Liver function tests

·        Renal function tests

 

The 2014 sexual performance study similarly found no clinically significant abnormalities in liver or kidney function testing, with adverse events evenly split between active & placebo groups (3 vs. 4, respectively) .

 

The Caution: Liver Injury Reports Exist But Context Matters

 

The NIH's LiverTox database documents isolated reports of clinically apparent liver injury attributed to Tongkat Ali . However, the evidence is nuanced:

 

·        Most cases involve young male bodybuilders, and the possibility of unacknowledged anabolic steroid use weakens the evidence that Tongkat Ali alone caused the injury .

·       In short-term clinical studies, no changes in serum ALT, AST, or bilirubin were observed

·        The LiverTox likelihood score is "D" (possible rare cause) — not a definitive causative link .

 

Who Should Avoid Tongkat Ali?

 

Based on current evidence, certain groups should exercise caution :

 

·        Individuals with prostate cancer (testosterone may stimulate growth)

·        Those with known liver disease (cirrhosis, hepatitis)

·        People with hormone-sensitive conditions

·        Pregnant or breastfeeding women (safety data lacking)

·        Those on cardiovascular medications (potential interactions)

 

Side Effects to Watch For

 

At conventional doses (100–400mg daily), side effects are uncommon but may include :

 

·        Nausea or stomach discomfort

·        Diarrhea

·        Headaches

·        Rash

·        Irritability or insomnia at high doses

Part III: What Makes Nu‑Prep Different?

 

With 26 clinical studies backing it, the PHYSTA® water extraction process sets Nu‑Prep apart. Unlike products using harsh solvents, PHYSTA® uses a patented water-based method that preserves the full spectrum of bioactive compounds — including quassinoids, glycoproteins, & polysaccharides .

 

This standardization ensures:

·       Consistent potency in every capsule

·       Clinically validated efficacy at doses as low as 100mg

·       Safety backed by peer-reviewed research
