Virilast Proprietary Blend
Also known as: Virilast Proprietary Blend, Male sexual health blend, ED supplement blend
Overview
Virilast Proprietary Blend is a commercial supplement blend marketed to improve male sexual performance, specifically erectile function. While the exact composition is not publicly disclosed, such blends typically combine herbal extracts (e.g., Panax ginseng, Tribulus terrestris), amino acids (e.g., L-arginine), and other nutraceuticals. These ingredients are chosen for their purported effects on erectile function, often by enhancing nitric oxide synthesis and improving penile blood flow. The blend is intended for men experiencing mild to moderate erectile dysfunction. There is no direct research on the Virilast Proprietary Blend itself; therefore, its efficacy and safety are inferred from studies on its common individual components. The quality of evidence for these individual ingredients varies, with some supported by robust clinical trials and meta-analyses.
Benefits
The primary benefits of ingredients commonly found in blends like Virilast include statistically significant improvements in erectile function, as measured by scores like the International Index of Erectile Function (IIEF). For instance, Panax ginseng and L-arginine have shown mean differences of approximately 5 to 6 points in IIEF scores compared to placebo in randomized controlled trials, which is considered a clinically meaningful improvement. These ingredients may also improve endothelial function and nitric oxide availability, thereby enhancing penile blood flow. The most significant benefits are observed in men with mild to moderate erectile dysfunction, encompassing both psychogenic and organic causes. Meta-analyses consistently report mean IIEF improvements of around 5 points. Benefits typically manifest after several weeks to a few months of consistent supplementation, usually within 4-8 weeks.
How it works
Many active ingredients commonly found in proprietary blends like Virilast primarily function by enhancing nitric oxide (NO) synthesis or its bioavailability. Increased NO leads to vasodilation, which improves blood flow to the penis, a critical factor for erectile function. For example, L-arginine serves as a direct precursor to NO, while Panax ginseng may stimulate NO production. Tribulus terrestris might influence androgen levels or directly impact endothelial function. These mechanisms involve molecular targets such as endothelial nitric oxide synthase (eNOS), androgen receptors, and vascular smooth muscle cells, all contributing to improved vascular health and erectile response. The absorption and bioavailability of these ingredients vary; L-arginine is generally well absorbed but has a short half-life, while herbal extracts' efficacy depends on their specific formulation.
Side effects
Ingredients commonly found in Virilast Proprietary Blend, such as Panax ginseng, Tribulus terrestris, and L-arginine, are generally well tolerated in clinical trials, with no serious adverse events frequently reported. Common side effects, occurring in over 5% of users, include mild gastrointestinal discomfort, headache, and flushing. Less common side effects (1-5%) may involve dizziness and dry mouth. Rare adverse events (less than 1%) have not been significantly reported in high-quality studies. However, potential drug interactions are a concern, particularly with antihypertensives, nitrates, and anticoagulants, due to the vasodilatory effects of some ingredients. Caution is advised for patients with pre-existing cardiovascular disease or those on medications that affect blood pressure. Data on safety in special populations, such as the elderly or individuals with severe comorbidities, remains limited.
Dosage
The minimum effective dose for individual ingredients varies; for example, Panax ginseng is typically effective at 900–1000 mg/day, and L-arginine at 1.5 to 5 g/day. However, for proprietary blends like Virilast, optimal dosage ranges are difficult to determine because the exact amounts of each ingredient are not disclosed, complicating precise dosing recommendations. The maximum safe dose for such blends is also not well established, though individual ingredients have known upper limits. Daily administration for at least 4-8 weeks is generally required to observe benefits. These supplements are commonly available in capsule or tablet form. Food intake and specific formulation can influence absorption. While some ingredients may require cofactors for optimal effect, this is highly dependent on the specific blend's composition.
FAQs
Is Virilast Proprietary Blend effective?
The effectiveness depends on the specific active ingredients present and their dosages. Without full disclosure of the exact composition, the overall efficacy of the blend cannot be definitively confirmed, though individual components may be effective.
Is Virilast Proprietary Blend safe?
It is generally considered safe if the individual ingredients are standard and appropriately dosed. However, caution is advised due to potential interactions with certain medications, especially for individuals with cardiovascular conditions.
How long does it take to see results from Virilast Proprietary Blend?
Benefits are typically observed after consistent daily administration for at least 4 to 8 weeks, as reported for the active ingredients commonly found in such blends.
Can Virilast Proprietary Blend replace prescription ED medications?
No, supplements are not considered first-line therapy for erectile dysfunction and lack the robust evidence and regulatory oversight of prescription medications like PDE5 inhibitors. Consult a healthcare professional for ED treatment.
Are proprietary blends less reliable than single-ingredient supplements?
The lack of transparency regarding the exact dosages of individual ingredients in proprietary blends can reduce their reliability and make it difficult to reproduce specific effects or assess precise safety profiles.
Research Sources
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10490034/ – This systematic review and meta-analysis evaluated dietary supplements for erectile dysfunction, identifying Panax ginseng, Tribulus terrestris, and L-arginine as effective ingredients. It reported statistically significant improvements in IIEF scores (mean difference ~5 points, p<0.05) based on high-quality RCTs, confirming moderate-quality evidence for these components.

It concluded that supplements containing class A and B ingredients (e.g., Panax ginseng, L-arginine) significantly improved erectile function scores over placebo after two months of treatment (p<0.01), with minimal reported side effects, supporting their use in ED management.
- https://www.jomh.org/articles/10.22514/jomh.2025.076 – A meta-analysis on antioxidant supplementation for ED found a mean IIEF-EF improvement of 5.5 points (p<0.001) with antioxidant supplements. This supports the role of such components, often found in proprietary blends, in ED management and notes their good safety profiles.
