4.9 Over 200,000 Boosted Men

Hard +

Take 45 minutes before sex for a boost 🚀, and take daily to build a routine that’s great for your heart, fitness, and erectile health. Men that take the ingredients in Prime Hour for 30 days reported a 50% increase in erection quality.

Why Prime Hour?

We wanted better performance and sexual wellness in the bedroom, but our options were terrible. Prescriptions come with all sorts of side effects and the over-the-counter gas station pills are sketchy and fraudulent. We knew we could do better, so we started Prime Hour and created our all natural HARD+ with best-in-class scientists and biochemistry PhDs.

How to Take It & What to Expect

Simply tear open the sachet and mix with 6-8 ounces of water, just like your favorite electrolyte packet. For best use, consume anywhere from 45 minutes to 4 hours prior to activity. You’ll notice better blood flow, better erection quality and firmness.

Also take it as a daily supplement to support general cardiovascular and heart health, athletic performance in and outside of the gym, healthy blood pressure, and to support erectile function generally.

How it works

Step 1: Increases Nitric Oxide Production

After consuming our HARD+, blood levels of arginine, citrulline, and nitrate will increase. This supports nitric oxide (NO) production

Step 2: Stimulates blood flow

Boosted NO dilates blood vessels, enhancing blood flow to the penis and throughout the body. Meanwhile, vitamin C's antioxidant action protects nitric oxide from oxidative degradation.

Step 3: Reap the benefits

Better blood flow = better erections. Additionally, increased circulation contributes healthier blood pressure, improved athletic performance, and enhanced muscle pumps. during workouts.

Better blood flow: erection strength, increased stamina, cardiovascular health, athletic performance and reduced blood pressure

Everything You Need To Know

How does it work?

After consuming our HARD+, blood levels of arginine, citrulline, and nitrate will increase. This supports nitric oxide production which facilitates increased blood flow to the penis. Meanwhile, the antioxidant action of vitamin C will protect nitric oxide from oxidative degradation, which further enhances the effects of nitric oxide on blood flow. Ginseng also increases nitric oxide activity, in addition to reducing feelings of fatigue while increasing arousal and sexual satisfaction. Collectively, these effects enhance drive and blood flow to the penis, resulting in better performance.
