When it comes to volume enhancement supplements, Semenax is one of the original players—launching in 2003 and remaining relevant for over 20 years. That’s remarkable in an industry where most products disappear within a few years.
I purchased a 3-month supply and tested it for 75 days with 10 other men. Here’s the complete breakdown.
What Is Semenax?
Semenax is a volume enhancement supplement designed to increase ejaculate volume for more intense orgasms. Unlike some products that focus on erection quality, Semenax specifically targets the seminal vesicles and prostate—organs responsible for producing seminal fluid.
Key targets:
- Increased ejaculate volume
- More intense orgasms
- Improved fertility potential
- Better sexual confidence
- Enhanced sexual performance
What sets Semenax apart is its comprehensive approach—targeting not just volume but also sperm count and overall reproductive health.
Our Testing Methodology
We conducted a 75-day test:
- Duration: 75 consecutive days
- Dosage: 4 capsules daily (2 in morning, 2 evening)
- Measurement: Weekly volume measurements (standardized)
- Tracking: Subjective intensity ratings, partner feedback
- Testers: 10 men ages 25-48
