ProSolution Plus Review 2026 — The Clinical Study Explained

Introduction: What You Need to Know

ProSolution Plus is a blend of seven Ayurvedic herbs (Tribulus, ashwagandha, Asparagus adscendens, Mucuna pruriens, Asteracantha longifolia, Curculigo orchioides and shilajit), marketed for staying power and sexual function. Unusually for this category, the same seven-herb formula was tested in a published, randomized, placebo-controlled trial (Kulkarni et al., 2011). Its 148 men had a mix of complaints, results were questionnaire scores rather than timed ejaculation, the higher dose did no better than the lower one, and the authors were affiliated with the developer. For a head-to-head with our erection-support pick, see VigRX Plus vs ProSolution Plus.

Our Top Pick Among Men's Staying-Power Formulas: ProSolution Plus

A seven-herb Ayurvedic blend from Leading Edge Health marketed for staying power. Its formula has one 60-day, developer-linked placebo-controlled trial. ProSolution Plus may suit healthy men whose main concern is finishing too soon and who want a supplement with at least one placebo-controlled trial of its formula. That trial was short and developer-linked, and the herbs carry real interaction concerns, so it is not a substitute for proven PE treatments or a doctor's advice.

How to Evaluate Products in This Category

Before looking at individual products, these are the checks that matter most:

• Dose alignment with published research: An ingredient at a fraction of the studied dose is unlikely to match the research. Check whether the label discloses each dose and compare it with the amounts used in human studies.
• Published human evidence: Look for a published, placebo-controlled trial of the product itself. Most products in this category have none and rely on ingredient studies, animal data or traditional use.
• Branded ingredients: Branded extracts (such as KSM-66, Sensoril, Cognizin, Furosap or SYN-COLL) are standardized, and some have their own studies, often funded by the supplier. A brand name alone doesn't mean the product uses a studied dose.
• Manufacturing and testing: Supplements sold in the US must be made under the FDA's current good manufacturing practice (cGMP) rules. An independent certificate of analysis is a useful extra check on purity and dose.
• Refund terms: Read the conditions, not just the number of days. Many guarantees require containers to reach the warehouse within the window and don't refund shipping.

#1 — VigRX Plus — Detailed Analysis

Top pick: male sexual-health supplements | 67-Day Money-Back Guarantee (seller's terms apply)

An herbal blend (ginseng, ginkgo, damiana, saw palmetto and others) for male sexual function from Leading Edge Health, with one small 2012 placebo-controlled trial of the product.

VigRX Plus may suit healthy men with mild erection concerns who want a herbal product with at least one published placebo-controlled trial behind it. That trial was small, short, of unclear funding and used a different, higher-dose formula, so expectations should be modest, and anyone on blood thinners, diabetes or heart medicines should check with a doctor first.

What We Found

• Formula: The current official site lists eight ingredients: damiana, Asian red ginseng, muira puama, hawthorn, catuaba, saw palmetto, ginkgo and Bioperine (black pepper extract), 1 pill twice a day. Per-ingredient amounts aren't shown on the sales page.
• Evidence: One published 12-week placebo-controlled trial of the product (Shah et al., 2012; 75 men completed) reported better erectile function scores than placebo. It was small, its funding isn't stated, and it tested an older 11-ingredient formula at double the current dose.
• Guarantee: 67-day money-back guarantee. Try for 60 days; containers must reach the warehouse within 67 days of delivery, "no exceptions"; shipping is not refunded; one refund per customer.
• Cautions: Check with a doctor first if you take blood thinners or diabetes, heart or blood pressure medicines. Persistent erection problems can be an early sign of heart disease.

#2 — ProSolution Plus — Detailed Analysis

Top pick: men's staying-power formulas | 67-Day Money-Back Guarantee (seller's terms apply)

A seven-herb Ayurvedic blend from Leading Edge Health marketed for staying power. Its formula has one 60-day, developer-linked placebo-controlled trial.

ProSolution Plus may suit healthy men whose main concern is finishing too soon and who want a supplement with at least one placebo-controlled trial of its formula. That trial was short and developer-linked, and the herbs carry real interaction concerns, so it is not a substitute for proven PE treatments or a doctor's advice.

What We Found

• Formula: Seven Ayurvedic herbs, with no amounts shown on the official site: Tribulus terrestris, ashwagandha, Asparagus adscendens, Mucuna pruriens, Asteracantha longifolia, Curculigo orchioides and shilajit. It does not contain Butea superba.
• Evidence: The seven-herb formula was tested in one 60-day, developer-linked placebo-controlled trial of 148 men (Kulkarni et al., 2011), which reported better erectile function and premature ejaculation scores than placebo. It hasn't been independently replicated.
• Guarantee: 67-day money-back guarantee. Try for 60 days; containers must reach the warehouse within 67 days of delivery, "no exceptions"; shipping is not refunded; one refund per customer.
• Cautions: Mucuna contains L-dopa (avoid with Parkinson's medicines or MAO inhibitors unless a doctor approves), and ashwagandha can interact with thyroid, diabetes, blood pressure and sedative medicines.

Pros and Cons

• ✓ Formula tested in a published randomized, placebo-controlled trial
• ✓ Side effects in the trial were mostly mild and similar to placebo
• ✓ Established seller with a written 67-day guarantee
• ✗ Only one trial, run by the formula's developer, with no funding statement
• ✗ Higher dose did no better than the low dose
• ✗ Doses not shown on the website
• ✗ Mucuna (L-dopa) and ashwagandha raise drug-interaction concerns

#3 — VigRX Delay Spray — Detailed Analysis

Best for: on-demand delay (topical) | Guarantee terms unverified

A water-based topical delay spray from Leading Edge Health that uses benzocaine, a local anesthetic, plus several botanical extracts, applied about 10 minutes before sex.

VigRX Delay Spray may suit men who want an on-demand topical option for finishing too soon, since benzocaine-type desensitizers have reasonable general support. The spray itself has no published study, its benzocaine strength isn't disclosed and the claimed 64% result has no source we could find.

What We Found

• Formula: A water-based topical spray whose active ingredient is benzocaine, a local anesthetic, plus botanical extracts. The benzocaine strength isn't stated on the seller pages we read. Use 1 to 3 sprays about 10 minutes before sex.
• Evidence: No published study of the spray. Topical anesthetics as a class have trial evidence for delaying ejaculation; for benzocaine, one small maker-funded trial of 4% wipes (a different brand) reported a modest delay.
• Guarantee: Not clearly stated on the seller pages we read, so check the returns policy before buying. Optional subscriptions are offered; choose a one-time purchase if you don't want recurring orders.
• Cautions: Can cause numbness, irritation or loss of erection, and can transfer to a partner. Don't use it if you're allergic to benzocaine or other ester-type local anesthetics.

#4 — Erectin — Detailed Analysis

Alternative pick: male sexual-health supplements | 67-day guarantee advertised (terms not confirmed)

Herbal softgel from Leading Edge Health with 10 botanicals (including ginkgo, hawthorn, saw palmetto and tribulus) plus BioPerine, sold for male sexual performance.

Erectin is a fully labeled multi-herb softgel from an established maker, which may suit men who want to try a herbal option and are comfortable using the 67-day guarantee. The main caveat is evidence: no published trial of Erectin exists, and most herbs are dosed well below what studies used.

What We Found

• Formula: A softgel with 10 botanicals plus BioPerine. A label listing shows saw palmetto, ginkgo and hawthorn at 200 mg each, tribulus at 150 mg and smaller amounts of the rest (2 softgels a day); we couldn't confirm this is the current label.
• Evidence: No published trial of Erectin. Most herbs are dosed well below the amounts used in studies (for example, 50 mg of Korean red ginseng versus about 2,700 mg a day in small erection trials).
• Guarantee: 67-day money-back guarantee per third-party listings (not confirmed on the official site); shipping is not refunded.
• Cautions: Ginkgo can raise bleeding risk. Contains soy and bovine gelatin, so it isn't vegetarian.

Buying Guide: What to Look For

When evaluating any product in this category, check these points before purchasing:

• Full ingredient disclosure, with no proprietary blends hiding individual doses
• Made under FDA cGMP rules, ideally with an independent certificate of analysis
• A refund window long enough for a fair trial, with conditions you've read
• Purchase from the official site if you want to be able to use the money-back guarantee
• Realistic marketing claims, with no promises to cure anything or guarantee an outcome

Safety Considerations

The products discussed in this article are sold as dietary supplements, cosmetics or consumer devices, not medicines. They are not intended to diagnose, treat, cure or prevent any disease. These statements have not been evaluated by the Food and Drug Administration (FDA).

Always consult a qualified healthcare professional before starting any supplement, particularly if you take prescription medication, have an existing medical condition, or are pregnant or breastfeeding. Individual results vary.

Final Recommendation

ProSolution Plus is our top pick among men's staying-power formulas because its formula has a placebo-controlled trial behind it, but that trial was short and developer-linked, so expect modest results. Mucuna contains L-dopa and ashwagandha interacts with several medicines, so check with a doctor first if you take prescription drugs, and it isn't a substitute for proven premature ejaculation treatments. If erection quality is your main concern, our top pick for that is VigRX Plus. If you buy, use the official site so you can use the money-back guarantee, and read its conditions first.
