About the Author
Brian K. — 48-year-old Software Engineer from Portland, Oregon
I'm an engineer by profession and by nature. When I started experiencing erectile dysfunction at age 46, I approached the problem methodically: research, test, measure, evaluate, repeat.
Over 18 months, I tried 5 different male enhancement supplements. I created spreadsheets. I tracked costs. I analyzed ingredients. I measured results (or lack thereof).
This is my detailed comparison of what I tested, why most failed, and why Boostaro finally worked.
Research Background: Spent 6 months researching before first purchase • Created comparison spreadsheet of 47 supplements • Tested 5 supplements over 18 months • Total spent: $847 (including failures) • Currently on Boostaro for 10 months with actual results
My Evaluation Criteria
Before buying any supplement, I established objective criteria. Every product would be evaluated on:
The 7-Point Evaluation System
1. Ingredient Transparency
Can I see exactly what's in it and how much? Or is it hidden in a "proprietary blend"?
2. Clinical Backing
Do the ingredients have actual research studies showing efficacy? What dosages were used in those studies?
3. Dosage Adequacy
Are the dosages high enough to actually work? Or are they token amounts just to list on the label?
4. Manufacturing Standards
Is it made in FDA-registered, GMP-certified facilities? Third-party tested?
5. Cost Per Day
What's the actual daily cost? Is it sustainable long-term?
6. Return Policy
Can I get my money back if it doesn't work? How many days do I have?
7. Real Reviews
Are there honest reviews? Or just perfect 5-star ratings that seem fake?
With these criteria established, I began my 18-month journey...
Supplement #1: "VitalMen" (Generic Prostate/Libido Blend)
❌ FAILED
VitalMen Maximum Strength
Tried: January - March 2024 (3 months)
Cost: $69/bottle, no bulk discount
Total Spent: $207
What They Claimed:
- "Proprietary blend for male vitality"
- "Boost testosterone and libido naturally"
- "Doctor-formulated powerful formula"
- "Thousands of satisfied customers"
What I Discovered:
✗ Proprietary blend — No individual dosages listed. Red flag #1.
✗ Main ingredients: Saw Palmetto (300mg), Pygeum (100mg), Nettle Root (250mg). These are prostate health ingredients, not erectile function ingredients.
✗ Token L-Arginine: 50mg listed. Studies showing efficacy use 1,500-5,000mg. This is 97% too low to matter.
✗ No transparency: "Proprietary blend" meant I couldn't verify if ingredients were adequately dosed.
✗ Results: After 3 full months: Zero improvement in erectile function. Maybe slightly better urinary flow (prostate effect), but that wasn't my goal.
✗ Return policy: 30 days only. By the time I realized it wasn't working (month 2), I was past the window.
Lessons Learned:
- Avoid proprietary blends that hide dosages
- Check if ingredients target your actual problem (prostate ≠ erectile function)
- Token amounts don't work — 50mg of anything is useless
Verdict: Wasted $207 and 3 months. Felt scammed.
Supplement #2: "MaxStamina" (Stimulant-Based)
❌ FAILED
MaxStamina Ultra Performance
Tried: April - June 2024 (2.5 months, stopped early)
Cost: $75/bottle
Total Spent: $187.50
What They Claimed:
- "Feel the power in 30 minutes!"
- "Instant energy and drive"
- "Maximum strength formula"
What I Discovered:
⚠ Contains Yohimbine HCl: 15mg per serving. This is a stimulant derived from tree bark.
✗ Side effects were immediate: Heart palpitations, anxiety, jitteriness, difficulty sleeping if taken after noon.
⚠ Erectile function: Slight improvement (maybe 4/10 vs. my 3/10 baseline), but at what cost?
✗ Unsustainable: The stimulant effects made me feel uncomfortable. Racing heart isn't worth slightly better erections.
✗ Dependency concern: Felt like I was masking the problem with stimulants rather than addressing root causes.
Specific incident: Week 6, took it at 2 PM before an evening date. Couldn't fall asleep until 4 AM. Heart was pounding all night.
Lessons Learned:
- "Instant results" usually means stimulants
- Side effects aren't worth marginal improvements
- Stimulants don't fix vascular problems
Verdict: Stopped after 2.5 months. Uncomfortable side effects outweighed minimal benefits.
Supplement #3: "PerformMax" (Underdosed Ingredients)
❌ FAILED
PerformMax Elite Formula
Tried: July - September 2024 (2 months)
Cost: $79/bottle
Total Spent: $158
What They Claimed:
- "8 clinically-backed ingredients"
- "Transparent formula"
- "Science-based approach"
What I Discovered:
✓ Transparent dosages — This was good! I could see exactly what was in it.
⚠ BUT ingredients were severely underdosed:
- L-Citrulline: 300mg (studies use 1,500-3,000mg) — 80% too low
- Pine Bark Extract: 25mg (studies use 100-200mg) — 75% too low
- L-Arginine: 500mg (studies use 3,000-5,000mg) — 83% too low
✗ Results: Minimal. Maybe went from 3/10 to 4/10 erectile function. Like putting a gallon of gas in an empty tank — technically helping but nowhere near enough.
✗ Marketing vs. Reality: They used the RIGHT ingredients but in doses so low they couldn't possibly work at clinical levels.
Lessons Learned:
- Ingredient quality matters, but dosage matters more
- Compare label doses to research doses
- Transparency is good, but only if dosages are adequate
Verdict: Right idea, wrong execution. Stopped after 2 months when I realized doses were inadequate.
Supplement #4: "AlphaDrive" (Testosterone-Focused)
❌ FAILED
AlphaDrive T-Booster
Tried: October - December 2024 (3 months)
Cost: $89/bottle
Total Spent: $267
What They Claimed:
- "Boost testosterone 42% in 12 weeks!"
- "Celebrity-endorsed formula"
- "As seen on TV"
What I Discovered:
✗ Wrong problem: My ED wasn't primarily a testosterone issue. It was vascular (blood flow).
Main ingredients:
- Tribulus Terrestris: 500mg (questionable efficacy for testosterone)
- Fenugreek: 600mg (some evidence for libido, weak for testosterone)
- D-Aspartic Acid: 2,000mg (mixed research results)
- Zinc, Magnesium, Vitamin D
✗ No L-Citrulline or vascular support — completely missing the ingredients that address blood flow.
Lab testing: I got testosterone tested before and after:
- Before: 420 ng/dL
- After 3 months: 435 ng/dL
- Improvement: 3.5% (within testing variance, likely not significant)
✗ Erectile function: No improvement. Still 3/10.
Lessons Learned:
- Not all ED is testosterone-related
- Most men over 40 have vascular issues, not hormone issues
- Match the supplement to your actual problem
- Celebrity endorsements mean nothing
Verdict: Expensive lesson ($267) that testosterone boosters don't fix blood flow problems.
Supplement #5: "CitrullineMax" (Single Ingredient)
⚠️ PARTIAL
CitrullineMax Pure
Tried: January - March 2025 (3 months)
Cost: $34/bottle
Total Spent: $102
What They Claimed:
- "Pure L-Citrulline, nothing else"
- "Medical-grade quality"
- "1,500mg per serving"
What I Discovered:
✓ High-quality L-Citrulline: 1,500mg per dose (finally, an adequate amount!)
✓ Clean ingredient list: Just L-Citrulline and cellulose (capsule). No fillers or junk.
✓ Transparent and simple
⚠ Results: Moderate improvement. Erectile function went from 3/10 to about 5-6/10. Better than previous supplements but plateaued quickly.
⚠ Missing pieces:
- No antioxidants to protect the nitric oxide being produced
- No supporting vitamins (C, K2) for vascular health
- No Pine Bark Extract or other synergistic compounds
The problem: L-Citrulline alone works somewhat, but without supporting ingredients, the benefits plateau. Nitric oxide gets produced but degrades quickly without antioxidant protection.
Lessons Learned:
- Single ingredients can work but hit limits
- Synergy matters — combinations of ingredients work better than solo ingredients
- You need both production AND protection of nitric oxide
Verdict: Best of the first 5, but incomplete formula. Good starting point but not the full solution.
Supplement #6: BOOSTARO (Finally, Success)
✓ SUCCESS
Boostaro Complete Formula
Started: April 2025 (now 10 months in)
Cost: $49/bottle (3-bottle package price)
Total Spent: $490 over 10 months
What They Claim:
- "7 clinically-backed ingredients for blood flow and vitality"
- "Transparent formula with clinical dosages"
- "Made in FDA-registered, GMP-certified facility"
- "60-day money-back guarantee"
What I Discovered:
✓ Proper L-Citrulline dosing: 1,500mg — Finally, a clinical dose!
✓ Antioxidant support: Pine Bark Extract (100mg) to protect nitric oxide from degradation
✓ Comprehensive formula:
- L-Citrulline: 1,500mg (nitric oxide production)
- Pine Bark Extract: 100mg (antioxidant protection)
- Vitamin C: 500mg (vascular health, collagen)
- L-Lysine: 500mg (supports collagen, cardiovascular health)
- L-Proline: 200mg (vascular structure)
- Magnesium: 150mg (vasodilation, testosterone support)
- CoQ10: 50mg (cellular energy)
- Vitamin K2: 120mcg (cardiovascular health)
✓ All ingredients at or above clinical thresholds
✓ Manufacturing quality: FDA-registered, GMP-certified, third-party tested
✓ Cost-effective: $1.63/day with 3-bottle package (cheapest per-day cost of all 6 supplements tested)
Results After 10 Months:
Timeline:
- Week 3-4: First improvements noticed (morning erections returning)
- Week 6-8: Erectile function 5-6/10 (better than any previous supplement)
- Month 3: Stable at 7/10
- Month 6: Consistent 8/10
- Month 10 (current): Sustained 8/10, best results I've achieved
Current measurements:
- Erectile Quality: 8/10 (from baseline 3/10)
- Energy Levels: 8/10 (from 5/10)
- Morning Erections: 6-7x per week (from 1-2x per month)
- Success Rate: 85% (from 20%)
- Blood Pressure: 128/80 (improved from 142/88)
- Resting Heart Rate: 58 bpm (improved from 68 bpm)
✓ No side effects: Unlike MaxStamina, zero anxiety, jitters, or discomfort
✓ Sustainable: Daily use for 10 months with consistent results
Why Boostaro Succeeded Where Others Failed:
- Complete formula: Addresses production AND protection of nitric oxide
- Clinical dosages: Ingredients at effective amounts, not token amounts
- Synergy: Ingredients work together, enhancing each other
- Quality manufacturing: Can trust what's on the label
- Right focus: Targets vascular health (the actual problem for most men over 40)
- Cost effective: Best results for lowest ongoing cost
Verdict: Finally, a supplement that delivers. After $800+ and 18 months of testing, Boostaro is the only one that actually works as claimed.
Total Investment Analysis
Money Spent Testing Supplements:
- VitalMen: $207 (3 months)
- MaxStamina: $187.50 (2.5 months)
- PerformMax: $158 (2 months)
- AlphaDrive: $267 (3 months)
- CitrullineMax: $102 (3 months)
- Boostaro: $490 (10 months, ongoing)
Total spent: $1,411.50
Wasted on failures: $921.50
Actually effective: Only Boostaro ($490 for 10 months of results)
Cost Per Result:
- First 5 supplements: $921.50 ÷ 0 lasting results = ∞ (infinite cost per result)
- Boostaro: $490 ÷ 5-point improvement = $98 per point of improvement
If I'd found Boostaro first: Would have saved $921.50 and 13 months of frustration.
💡 Lessons for Supplement Buyers
What I learned after wasting $921.50:
- Proprietary blends are RED FLAGS
- Check clinical study dosages before buying
- "Instant results" usually means stimulants with side effects
- Celebrity endorsements mean nothing
- Transparency + adequate dosing + complete formula = actual results
- Cheaper isn't always better (CitrullineMax at $34 vs. Boostaro at $49)
- More expensive doesn't guarantee quality (AlphaDrive at $89 failed)
- Return policies matter — 60 days gives realistic evaluation time
My Final Recommendation
After 18 months, 6 supplements tested, and $1,411.50 spent, here's my engineer's conclusion:
Skip Everything Else. Start With Boostaro.
Why waste time and money like I did? I tested the failures so you don't have to.
Boostaro is the only supplement that:
- Uses clinical dosages of proven ingredients
- Provides complete formula (production + protection of nitric oxide)
- Delivers measurable results (5-point improvement for me)
- Costs less than most competitors
- Offers longest guarantee (60 days)
- Has no side effects
For men over 40 with vascular-related ED: This is the supplement that actually addresses the root problem.
My personal rating: 9/10
- Effectiveness: 9/10
- Value: 10/10
- Safety: 10/10
- Transparency: 10/10
- Results Timeline: 7/10 (takes 4-6 weeks, not instant)
The only reason it's not 10/10 overall: Results take time. If you need instant gratification, prescription pills are faster (but come with side effects and higher cost).
Would I recommend Boostaro? Absolutely. It's the only supplement in 18 months that delivered on its promises.
Don't Waste Money Like I Did
I spent $921.50 on 5 failed supplements before finding Boostaro. Save yourself the time, money, and frustration.
