Did you know? There’s actually an “official scale” for how hard your penis gets when erect,
and you can even compare it to everyday foods—it’s easy to understand at a glance.
🔹Level 4 = Cucumber: Firm all the way through, with taut skin and flesh. This is a man’s peak condition.
If your partner is at cucumber level… congratulations, he’s really doing great.
🔹Level 3 = Unpeeled banana: The hardness of a typical healthy man. Most people are here.
It’s not ridiculously hard, but everything works just as it should.
🔹Level 2 = Peeled banana: Starting to feel soft and less firm.
This may be a sign of “early erectile dysfunction,” so take note.
🔹Level 1 = Konjac jelly: Really too soft—this is usually typical erectile dysfunction.
It’s often related to blood vessels, stress, lifestyle habits, and cardiovascular risks.
✅ If you find that you’re often at Level 1–2, or can’t maintain firmness consistently, we recommend seeking help from a urologist.
How can you improve erection hardness?
1️⃣ Medication (most common)
Medications such as Viagra and Cialis mainly help improve blood flow, with noticeable short-term effects.
2️⃣ Testosterone replacement (only if levels are confirmed to be low)
People whose blood tests show “low testosterone” need supplementation,
and it’s not recommended for couples who are trying to conceive.
3️⃣ Low-intensity shockwave therapy (a lot of people have been asking about this lately)
Sound waves are used to stimulate the corpus cavernosum,
helping generate new blood vessels and improve blood flow. It’s an approach that “treats the underlying cause.”
It’s painless, needle-free, and requires no surgery. You can go to work right afterward.
Lastly, let’s talk about shockwave therapy. Many men are curious:
Who is it suitable for?
✔ Mild to moderate erectile dysfunction
✔ People looking for a more natural, long-term approach
🔹How often?
Once a week, for about 10 minutes,
with 6–12 sessions typically making up a complete course of treatment.
🔹How long do the effects last?
Effects last 6 to 12 months
🔹How much does it cost?
Price per session: 4,000~6,000
Price for 6 sessions: 24000-36000
🔹Does it hurt?
No. There’s no bleeding and no needles.
You can go straight to work, eat, or go on a date afterward.
