Yeon's Talk

A legendary medicine loved by stars and examinees

"

It becomes a powerful force in moments that require top-tier performance.

It is a tonic taken before stepping onto the stage not only by Lee Hyori, Cha Eun-woo, BTS Jungkook, and Le Sserafim Chaewon, but also by pianist Im Dong-hyuk, who conquered the world's top 3 competitions. The choice of world-class artists is Gongjindan.

The choice of world-class artists
"

Entrance exams are ultimately a battle of stamina and mental strength.

Musk acts directly on the brain to clear the mind and maximize concentration. Instead of taking it only on the day of the exam, we recommend taking one pill a day on an empty stomach starting at least 2-3 months before (e.g., D-100) to create a routine for your best condition.

The Golden Time elixir for examinees
"

It is different when you need consistent fluid supplementation rather than a short-term energy explosion.

Through Yon Korean Medicine Clinic's unique preparation method—meticulously crafted by double-boiling four ingredients (Ginseng, Rehmannia root, Poria, and honey) in traditional earthenware pots for several days—it exerts excellent effects in gently supplementing bodily fluids and energy.

With the mindset that I and my children will consume it, I protect cleanliness and safety as if it were my life.

Fact Check

proven by science

The director will answer you directly.

Yes, you can. As a result of the director wearing a continuous glucose monitor (CGM) for 30 consecutive days and taking it on an empty stomach, it did not cause a blood sugar spike, and the rise was very gentle, within 5-15. Please consult with an expert before taking it with peace of mind.

Red ginseng is a single herb that has a heating property, but Gyeongokgo is a complex herbal medicine made of a balanced combination of Rehmannia root, Poria, and honey to soothe heat. For Gongjindan, health functional foods on the market cannot contain the pharmaceutical ingredient 'authentic Musk', so only the Korean medicine clinic's prescription is true Gongjindan.

If you compare the price per gram, that is not the case. Commercial products are mixed with middle/lower parts with minimal effects, while Yon Korean Medicine Clinic generously uses only top-grade antler velvet and tips above the Gold Label SAT grade to produce overwhelming pharmacological activity.
