Research at GET HARDER

We separate interesting ideas from established evidence.

Clinical guidelines, peer-reviewed research, and expert commentary each have a place. They do not carry the same weight.

How we judge a claim

Not every source earns the same confidence.

We start with the strongest relevant evidence available, then make the limits visible.

Clinical guidelinesAuthoritative recommendations built from broad evidence and clinical judgment.
Systematic reviews + meta-analysesWhat multiple controlled studies collectively suggest.
Randomized trialsEvidence for specific interventions under defined conditions.
Observational researchUseful for associations, but unable to prove cause on its own.
Expert commentaryUseful for generating questions and explaining mechanisms, not equivalent to clinical evidence.

The conversation that sparked the question

Dr. Alok Kanojia on erectile function, cardiovascular health, and sexual conditioning.

The discussion begins around 1:13:36. It helped crystallize the product idea. We treat it as a starting hypothesis, not scientific proof.

Dr. Kanojia is a psychiatrist with experience at Harvard Medical School and Mass General Hospital. He is not presented here as a urologist or as someone who validated GET HARDER.

What we took seriously

Erection function is multifactorial.
Cardiovascular fitness deserves attention.
Anxiety and arousal context can matter.
Behavior and stimulation patterns are worth investigating.
Erection health should not be reduced to testosterone alone.

What we did not simply accept

One universal cause.
Pornography as a general explanation for ED.
Masturbation frequency as a proven cause.
A universal two-week physiological reset.
Any statistic without independent verification.

Visible restraint

What GET HARDER will not tell you.

We will not tell you pornography caused your erection problem.

We will not tell you checking off exercises means your erection improved.

We will not tell you fourteen days cures erectile dysfunction.

We will not tell you an app can diagnose what is happening.

We will not tell you to ignore persistent symptoms.

NIDDK notes that erection difficulties can involve vascular, neurological, hormonal, medication-related, emotional, and lifestyle factors. Diagnosis may require medical history, examination, laboratory tests, and other testing.

Evidence into product

The research changes what the app does.

Aerobic activity has supportive evidence.Cardio can be a core program module.

Anxiety and stress may affect erectile function.Performance-context work can be offered where relevant.

Lifestyle risk factors matter.Smoking, alcohol, activity, and health context belong in the Hard Check.

Pornography and masturbation evidence is mixed.Sexual-habit answers should not automatically produce a causal verdict.

Persistent ED can have broader health significance.Some patterns should route toward professional evaluation instead of routine training.
