2/5 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 The company also refers to its own unpublished trials, which no one outside the company can check.

Studied Dose No studied dose exists for the blend, because no trial of Virilast has been published. The cited single-herb studies used their own doses, such as 1,500 mg a day of a Tribulus terrestris extract for 12 weeks and 240 mg a day of a branded ashwagandha extract for 60 days.
Active Compound Standardized blend of seven Ayurvedic herbs: Tribulus terrestris, Withania somnifera, Asparagus, Mucuna pruriens, Asteracantha longifolia, Curculigo orchioides, and shilajit.

Benefits

Sexual desire and function

There is no published trial of Virilast itself, and a PubMed search for the brand returns nothing, so the company's own sponsored results cannot be checked. What has been published involves single herbs from the blend, tested alone and in men with a diagnosed problem. Tribulus terrestris sold under a different brand name, at 1,500 mg a day for 12 weeks, improved sexual function scores versus placebo in 180 men with mild to moderate erectile dysfunction. A smaller study of 70 men tested Tribulus in men diagnosed with late-onset low testosterone. Ongoing trouble with erections is a medical issue worth raising with a doctor, since it can be an early sign of heart or blood vessel disease.

Male vitality and stress

One cited study tested ashwagandha on its own, not Virilast: a branded extract (Shoden) at 240 mg a day in 60 stressed but otherwise healthy adults for 60 days, which lowered morning cortisol and anxiety scores versus placebo. Testosterone rose over time in the men in that study, but the change was not statistically significant compared with placebo, and there was no change in women. The extract and dose used there are not the same as what this blend provides, and no cited study measured energy.

Antioxidant and circulation claims: not tested

None of the four studies cited on this page measured nitric oxide, blood flow, or antioxidant activity, in the blend or in its individual herbs. This is a marketing claim rather than a tested effect.

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

Generally well-tolerated.
Mild digestive upset is occasionally reported.
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 hormone-active herbs.
Diabetes or blood-pressure medication — monitor, as some herbs may add effects.
Tell your doctor about all supplements if you take medication.

This trial did not measure testosterone, and the men had a diagnosed condition.
  2. GamalEl Din SF, Abdel Salam MA, Mohamed MS, Ahmed AR, Motawaa AT, Saadeldin OA, Elnabarway RR Tribulus terrestris versus placebo in the treatment of erectile dysfunction and lower urinary tract symptoms in patients with late-onset hypogonadism: A placebo-controlled study Urologia. 2019;86(2):74-78. doi:10.1177/0391560318802160.PubMedUsed to support: Small placebo-controlled study of Tribulus terrestris on its own, not Virilast, in 70 men diagnosed with late-onset low testosterone alongside erectile dysfunction and urinary symptoms. 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.
