When Kenyan fitness influencer S Gachau revealed he takes Viagra before gym sessions, the internet lit up.

Some called it genius. Others? Unbothered. But the big question remains:

Is it actually safe — or effective — to pop a Viagra before hitting the weights?

Let’s break it down.

What Viagra Actually Does

Viagra (sildenafil) works by relaxing blood vessels, which improves blood flow.

It was first developed to treat heart-related chest pain, then repurposed to help with erectile dysfunction.

So, in theory, more blood flow = better gym pumps?

Not exactly.

Here’s what researchers found:

No performance boost in strength, endurance or cardio

No extra energy or noticeable improvement for healthy people

Some benefit only at very high altitudes (above 3,800m)

Unless you're sprinting on Mt Kenya, it's unlikely to help.

Side Effects to Watch Out For

Using Viagra for workouts isn’t risk-free. It can cause:

Headaches

Dizziness

Flushed face

Low blood pressure

Vision issues

Nasal congestion

If you're taking heart meds or nitrate drugs, mixing them with Viagra can be dangerous.

Is There Any Legit Fitness Benefit?

Not really. Research shows that regular exercise is just as effective at improving blood flow and it comes without the side effects.

Working out

Better alternatives:

A balanced pre-workout meal

Good hydration

Consistent training

Proper rest and recovery

Caffeine (in moderation)

So Why Do Some Guys Still Use It?

For many, it’s psychological. Some feel more focused, energised, or “locked in” — but that’s more mental than physical.

Others might be chasing a pump or just experimenting after hearing hype online.

The Bottom Line

Viagra isn’t designed for fitness.

If you're healthy and training at normal altitude, there’s no reason to take it before a workout. It won’t help your lifts — and it could cause real problems.

Want better performance?

Stick to reps, not pills.
