Exstem is a cream enriched with human stem cell–derived exosomes. Applied to the highly absorbent scrotal area, it supports male performance, energy, drive, and skin firmness, helping counter the natural decline in cellular activity.
SL-NAD⁺ Supplement directly replenishes pure NAD⁺ using fast-absorbing WaferiX® technology, promoting noticeable improvements in energy production, focus, metabolism, and recovery.
By enhancing the cellular environment externally and cellular energy internally, the Reboost Set help with energy, performance, and overall strength, helping you stay powerful at work and in daily life.
商品の特徴
Exstem
A cream formulated with ultra-high-concentration human stem-cell culture supernatant (exosomes).
Applied to the scrotal area for high absorption, supporting fatigue recovery, lifestyle-related health, wrinkle and sagging improvement, erectile function, and male menopause symptoms—addressing anti-aging from both inside and out.
Made in Japan using stem cells sourced from rigorously quality-controlled donors.
Recommended for twice-daily use (morning and night). Many users report noticeable effects after more than one month of consistent use.
SL-NAD+
A sublingual supplement (WaferiX® patented technology) that absorbs NAD⁺ quickly without passing through the digestive tract.
Unlike NR/NMN precursors, it is designed to deliver pure NAD⁺ directly.
Studies show an average 59% increase in blood NAD⁺ levels after 2 weeks, and +76% after 6 weeks.
Vegetarian-friendly and gluten-free. Supports age-related cellular decline, fatigue, and reduced focus.
こんな方におすすめ
Men who feel age-related decline at the cellular level, such as poor morning energy, lingering fatigue, or difficulty concentrating.
Those experiencing symptoms of male menopause (reduced libido, stamina decline, loss of motivation) or reduced erectile hardness.
Anyone wanting anti-aging care that targets function and cellular health, not just outward appearance.
Those who want to combine internal supplementation with topical care to comprehensively restore vitality across all ages.
While no serious side effects are commonly reported, itching or allergic reactions may occur. If any abnormal symptoms appear during use, discontinue and consult a physician.
SL-NAD+
Due to the nature of supplements, some individuals may experience digestive discomfort (nausea, diarrhea), flushing, or itching. If you feel unwell, stop taking it and consult a doctor or pharmacist.

The NAD tablets are dissolved under your tongue. You can immediately feel better. A smooth boost of calm energy. Started on the cream. Looking forward to the results.
I was overcharged. My misunderstanding. Staff made it right.
Received the medication shipped out fast and well packaged.
The NAD is to be taken twice a day for the first two weeks. Really delicious. 🤤
I’ve used the cream once. Looking forward to seeing the results.
What are the benefits of combining these two products?
Exstem supports male function, fatigue recovery, and anti-aging, while SL-NAD⁺ enhances cellular energy, focus, and metabolism.
Together, topical + supplement delivers broader, deeper support than either product alone.
How soon can I expect results?
Some users report overnight improvements with exstem, and many experience noticeable effects within about a week.
For SL-NAD⁺, many feel increased energy, focus, and mood enhancement within a few days.
What happens if I stop using the products?
Benefits may diminish over time. Consistent use is recommended to maintain support for cellular function, male vitality, and NAD⁺ levels, which naturally decline with age.
