For those struggling with ED treatment

・Hoping to treat ED at its core and regain confidence as a man
・Having not been able to maintain an erection, which has saddened my partner
・Feeling embarrassed to visit the hospital
These are concerns shared by many middle-aged and older men. Conventional treatments like Viagra have only provided temporary solutions. That’s where exstem comes in. With the power of stem cell supernatant exosomes, it can lead to a fundamental treatment for ED.

Three benefits of using exstem

①No need to visit a hospital
It can be embarrassing and time-consuming to go to a hospital for ED treatment.
In contrast, exstem is applied to the scrotum just once or twice a day, making it a convenient and easy solution to maintain.
②Potential for Fundamental ED Treatment
ED medications like Viagra merely provide temporary relief by dilating blood vessels to induce an erection.
In contrast, the exosomes contained in exstem work to repair damaged cells.
They offer the potential for the regeneration of the nerves and blood vessels essential for achieving an erection.


③Made entirely in Japan
The stem cell donors used in exstem are Japanese individuals who meet stringent health standards. They undergo blood tests three times to confirm that they do not have any infections.
Every single step is carried out in facilities in Japan.
Feedback from users

According to a survey conducted with 24 exstem users, the feedback was as follows:
・More sustained erections: 62.5% (15/24 users)
・Increased frequency of morning erections: 70.8% (17/24 users)
・Enhanced erection hardness: 75% (18/24 users)
In addition, many users shared responses such as:
・During intercourse, my wife happily remarked, “You’re firmer now.”
・The frequency of morning erections clearly increased—from once or twice a week to nearly every day, leaving me feeling energized every morning.
・I can now maintain an erection during intercourse (previously, I couldn’t sustain it when changing positions).
Enhancing your erection quality with exstem can help you recapture the vigor and masculinity you experienced in your twenties.
Presented at the Annual Meeting of the Japanese Anti-Aging Medicine Society

Dr. Amano presented at the 24th Annual Meeting of the Japanese Anti-Aging Medicine Society an evaluation of the clinical efficacy of a cream containing human stem cell supernatant.
Title: Clinical Efficacy Evaluation of a Cream Containing Human Stem Cell Supernatant for the Treatment of ED and Andropause
In this study, patients suffering from andropause and ED were evaluated for the efficacy and safety of a cream containing human stem cell culture supernatant exosomes.
The results revealed significant improvements in erection hardness, function, and andropause symptoms based on various scores when comparing before and after use.

Frequently Asked Questions
Q. Are there any side effects?
A. This product is not a pharmaceutical, so tests for side effects have not been conducted; however, there have been reports of cases where itching and other symptoms occur. Additionally, allergic reactions to some of its ingredients have been observed. If you notice any abnormalities while using the product, please discontinue use and consult a dermatologist or similar specialist.
Q.How is quality control performed?
A.The product undergoes the following final checks to enhance safety:
・Sterility tests (using rapid microbial testing method/gas measurement method)
・Patch tests
・Mycoplasma tests (using the NAT method)
・Endotoxin tests (using the endpoint colorimetric method)
・Virus tests (for human viruses)
・Infectious disease tests via blood tests (performed at the time of stem cell collection)
Q. How is the manufacturing environment managed?
A.The manufacturing environment is managed in a clinic-associated cell culture processing facility (CPC), where sterilization is carried out using a Class 100 clean room and filtration. The Class 100 standard means an environment in which there are no more than 100 particles (0.5 μm or larger) per cubic foot of air (roughly equivalent to a cube of about 30 cm on each side). In Japan, this represents the highest level for a factory clean room, exceeding by two classes the standards required for pharmaceuticals, food, and similar products.
Q.How are the stem cell donors selected?
A.Donors are selected exclusively from healthy Japanese individuals who meet the following examination criteria and conditions:
• Multiple virus and bacterial tests (blood tests) are performed several times at monthly intervals.
• Source cell types and corresponding age conditions:
- Deciduous teeth: ages 6 to 8 years
- Adipose tissue: in their 20s or 30s
- Wharton’s jelly: in their 20s or 30s
In cases where tests are not passed, the procedures call for disposal in accordance with established protocols. Additionally, a serum-free culture medium specifically designed for adipose-derived stem cells (ADSCs) is used for cultivation.
Q.What type of stem cell culture supernatant is used?
A.This product contains three types of stem cell-derived culture supernatants:
• Human adipose-derived stem cell conditioned medium
• Human dental pulp cell conditioned medium
• Human cytokine mesenchymal stem cell exosomes
These have been carefully selected for their recognized high safety and effectiveness, and are manufactured under strict quality control.
Q.How is safety ensured during cultivation?
A.We use a serum-free medium specifically designed for the cultivation of adipose-derived stem cells (ADSCs). This medium has the following characteristics:
・It does not contain phenol red, thereby eliminating any estrogen-like effects.
・It is free of xenogeneic animal components (xeno-free), which helps avoid the risk of infections from animal-derived materials.
・It does not contain phenol red, thereby eliminating any estrogen-like effects.
Q.What effects have been confirmed?
A.In a study conducted by Dr. Amano, the growth factors contained in a cream formulated with human stem cell-conditioned medium were found to improve vascular endothelial function and increase blood flow, showing potential in alleviating symptoms of ED and male menopause.
Subjects: 10 healthy males (average age approximately 43 years).
Usage: Applied twice daily to the genital area and scrotum for 30 days.
Evaluation methods: Effects were measured using the International Index of Erectile Function (IIEF-5), the Aging Males’ Symptoms Scale (AMS), and the Erection Hardness Score (EHS).
Results:
1. IIEF-5 scores significantly improved (from 11.8 to 17.2, P < 0.001)
2. AMS scores also improved (from 46.3 to 37.6, P < 0.001)
3. The EHS did not reach statistical significance, but an improving trend was observed.
4. Participants reported increased morning erections, improved endurance during sexual intercourse, and reduced fatigue.

Q. What precautions should be taken during use?
A.Please avoid engaging in oral sex after using this product. For vaginal insertion, use a condom as a precaution. The active ingredients are absorbed within approximately 30 minutes, and washing after around 2 hours is considered acceptable. Additionally, the formulation is designed for 1 to 2 applications per day, so please avoid excessive use.
