Virilast® (Ayurvedic Men's Vitality Blend — Maypro)

Evidence Level
Preliminary
0 Clinical Trials
2 Documented Benefits
1/5 Evidence Score

Virilast® is a men's sexual-health blend from Maypro combining seven Ayurvedic herbs, including Tribulus terrestris, ashwagandha (Withania somnifera), Mucuna pruriens, and shilajit. No published clinical trial of the Virilast blend itself could be found, and a PubMed search for the brand name returns nothing. The four studies cited on this page each tested a single herb on its own rather than the blend, and most were run in men with a diagnosed condition such as erectile dysfunction, low testosterone, or infertility. The supplier calls the blend clinically studied but names no published trial that outsiders can check.

Studied Dose No studied dose exists for the blend; no trial of Virilast has been published. Cited single-herb studies used their own doses, such as 1,500 mg/day Tribulus and 240 mg/day of a branded ashwagandha.
Active Compound Standardized blend of seven Ayurvedic herbs: Tribulus terrestris, Withania somnifera, Asparagus adscendens, Mucuna pruriens, Asteracantha longifolia, Curculigo orchioides, and shilajit.

Benefits

Male sexual function

No trial of Virilast has been published, so the maker's own results cannot be checked. The evidence is for single herbs from the blend, tested alone. Tribulus terrestris sold as Tribestan (1,500 mg a day for 12 weeks) improved erectile function scores versus placebo in 180 men with mild to moderate erectile dysfunction. Ongoing erection problems deserve a doctor's check.

Stress and morning cortisol

One cited study tested an ashwagandha extract alone (Shoden, 240 mg a day for 60 days) in 60 stressed but healthy adults: anxiety scores and morning cortisol fell versus placebo. Testosterone rose in the men over time, but not significantly versus placebo. The extract and amount in Virilast differ, and no cited study measured energy or vitality.

Mechanism of action

1

Hormonal and dopaminergic support

This describes how the individual herbs are thought to work, not anything measured for the blend. Tribulus terrestris raised total testosterone in men diagnosed with late-onset low testosterone, and Mucuna pruriens raised testosterone, LH, and dopamine in men being screened for infertility. In the one study done in healthy people, the testosterone change was not significant versus placebo, and no cited study measured DHEA.

2

Nitric oxide and circulation

Nitric oxide is often offered as an explanation for herbs of this kind, but none of the studies cited on this page measured nitric oxide or blood flow, so this remains an idea rather than a finding.

Clinical trials

Side effects and drug interactions

Common Potential side effects

No safety study of the Virilast blend has been published.
In the single-herb trials cited here, side effects with Tribulus were no more common than with placebo, and no adverse events were reported with the ashwagandha extract.
In a small trial in older men, Tribulus taken for 3 months slightly raised AST, a liver enzyme, and PSA, a prostate marker; men having PSA tests should tell their doctor they take it.
Discontinue if any unusual reaction occurs. Ongoing trouble with erections deserves a doctor's assessment rather than self-treatment, since it can be an early warning sign of heart or blood vessel disease.

Important Drug interactions

Hormone-sensitive conditions: consult a doctor before taking herbs that may affect hormones.
Diabetes or blood pressure medication: ask your doctor first, as some of these herbs may add to their effects.
Tell your doctor about all supplements if you take medication.

Total testosterone rose. These were patients under medical care, so the result does not describe what this blend does for a healthy man.

It reported higher testosterone, LH, and dopamine along with better sperm measures. Infertility is a diagnosed medical condition treated under a doctor's care, so this says nothing about sexual desire or vitality in a healthy man.

Morning cortisol and anxiety scores fell versus placebo. Testosterone rose over time in the men, but that change was not statistically significant compared with placebo (P = .158), and there was no change in women, so this is not testosterone evidence.
