I am 38 years old and work in sales. I often have social engagements, sleep little, and occasionally feel less than ideal. I saw discussions on my social feed about [Japanese Tengsu male fast-acting health supplement / Japanese Tengsu energy booster / must-buy for men], and the price was acceptable, so I bought a box of the 50mg规格 to try.

The first time I used it was on a weekend evening, half an hour after dinner. After about 20 minutes, I started to feel the effects. The reaction was natural, not sudden. The whole process lasted over 3 hours, then gradually returned to normal.

The second time, I tried it on an empty stomach. It took effect faster, about 15 minutes, but I felt some stomach discomfort. The third time, I took it after a meal, and the onset time returned to about 25 minutes, feeling stable.

The product description mentions that the ingredients come from [赤根草], which can cleanse toxins from the body, promote testosterone secretion, and dilate corpus cavernosum blood vessels. These mechanisms sound reasonable. After half a month, I did feel more energetic and less fatigued.

The usage method is to take it after meals as per the instructions, avoiding an empty stomach. Precautions include consulting a doctor for those with high blood pressure or those taking medication. I didn't experience serious issues, but my face was slightly red and my nose a bit stuffy the first two times, which subsided after adaptation.

Disadvantages include the relatively high price, about 30-40 yuan per use, which is not cost-effective for long-term use; also, the packaging instructions are somewhat brief, requiring self-experimentation to determine post-meal use.
