Testo Blend Proprietary Blend
Also known as: Testo Blend, testosterone support blend, herbal testosterone booster, Testo Blend Proprietary Blend
Overview
Testo Blend Proprietary Blend is a combination of herbal extracts marketed to support testosterone levels, primarily used by men seeking to enhance sexual health or athletic performance. Common ingredients include fenugreek, ashwagandha, pomegranate, and cocoa extracts, each with some evidence for endocrine effects. These blends often feature standardized extracts in proprietary ratios. Research maturity is moderate for individual ingredients but low for proprietary blends as a whole. Evidence is strongest for individual ingredients, with several RCTs and systematic reviews, while evidence for proprietary blends is limited and often industry-sponsored. These blends are characterized by their multi-ingredient composition and are available in various forms, including capsules and powders.
Benefits
The benefits of Testo Blend Proprietary Blend are primarily linked to its individual ingredients. Fenugreek seed extract at 600 mg/day did not significantly increase serum testosterone in healthy older men in a 12-week RCT. Systematic reviews suggest ashwagandha root/leaf extracts may modestly increase testosterone in men, with effect sizes varying by study and population. A pomegranate/cocoa blend (LN18178) increased serum testosterone in healthy young males in a double-blind, placebo-controlled RCT, with a statistically significant effect (p < 0.05). Secondary effects include some evidence for improved sexual function, mood, and stress resilience, particularly with ashwagandha and pomegranate blends. Effects may be more pronounced in individuals with low-normal testosterone or under stress. Increases in testosterone are typically modest (less than 20% from baseline), with uncertain clinical significance for healthy individuals. Effects may be observed within 4–12 weeks of supplementation.
How it works
The mechanism of action for Testo Blend Proprietary Blend varies by ingredient. Fenugreek may inhibit aromatase and 5-alpha-reductase, increasing free testosterone. Ashwagandha reduces cortisol, supports adrenal function, and may increase luteinizing hormone (LH), stimulating testosterone production. Pomegranate and cocoa have antioxidant and anti-inflammatory effects, possibly modulating nitric oxide and androgen receptors. These ingredients interact with the endocrine, reproductive, and stress response systems. Known molecular targets include androgen receptors, aromatase, 5-alpha-reductase, and cortisol receptors. Absorption and bioavailability vary by ingredient, but are generally moderate for herbal extracts.
Side effects
Testo Blend Proprietary Blend is generally well-tolerated in clinical trials. Common side effects (greater than 5%) include mild gastrointestinal upset from fenugreek and ashwagandha. Uncommon side effects (1-5%) include headache, dizziness, and allergic reactions. Rare side effects (less than 1%) include severe allergic reactions and liver enzyme elevations (rare, case reports). Drug interactions are possible with anticoagulants (fenugreek) and sedatives (ashwagandha). Contraindications include pregnancy, hormone-sensitive conditions, and allergy to any ingredient. Caution is advised in individuals with hormone-sensitive cancers, liver disease, or those on multiple medications. It's important to monitor for any adverse reactions and discontinue use if they occur.
Dosage
Minimum effective doses vary by ingredient: fenugreek at 300–600 mg/day of a standardized extract, ashwagandha at 300–600 mg/day of root/leaf extract, and pomegranate/cocoa blend (LN18178) at proprietary doses (exact amount not always disclosed). Optimal dosage ranges are 300–600 mg/day for fenugreek and ashwagandha; follow label instructions for proprietary blends. The maximum safe dose is not well established; avoid exceeding recommended doses. Typically taken daily, with or without food. Standardized extracts are preferred for consistency. Absorption may be enhanced with food for some ingredients. While no specific cofactors are required, balanced nutrition supports endocrine health.
FAQs
Is Testo Blend Proprietary Blend safe?
Generally safe for most adults; monitor for gastrointestinal or allergic reactions. Discontinue use if adverse effects occur.
When and how should I take Testo Blend?
Take daily, with or without food. Timing is not critical, but consistency is important for best results.
What results can I expect?

No, it is not a substitute for medical testosterone therapy. Effects are modest and variable, not comparable to hormone replacement.
Research Sources
- https://pmc.ncbi.nlm.nih.gov/articles/PMC8166567/ – This systematic review of RCTs examined the effects of fenugreek and ashwagandha on testosterone. It found that while some studies showed positive effects, results were inconsistent and not always statistically significant. A 12-week RCT included in the review showed that fenugreek did not significantly increase testosterone in healthy older men.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC9346391/ – This study investigated the effects of a pomegranate/cocoa blend (LN18178) on testosterone levels in healthy young males. The results indicated that LN18178 increased serum testosterone with statistical significance (p < 0.05). However, the exact effect size and confidence intervals were not always clearly reported.
