Two stars only for the glass vials that when you break them, you drink and pieces of glass. They couldn't include a bottle? I won't buy it again

mediocre to bad in performance. You can even tell from its light taste. Its worst characteristic is that its glass vials, when broken, leave small pieces of glass in your hand and it requires a lot of attention to not drop them into the glass you will drink from. The company needs to see this and maybe change it.

When I was 40 years old, I used to take these ampoules because I worked at weddings and baptisms on weekends and slept very little. Well, they do a very good job, you feel a pleasant shiver of coolness penetrating your body and you really stand on your feet and feel energized. However, at 46, when I took them again once, it caused me a lot of dizziness to the point where I couldn't stand upright, which lasted for a few hours. After a few weeks, I tried again to see if it was the cause. Unfortunately, I experienced dizziness again and had to throw them away. Maybe it was an isolated incident.

I have been using these specific ampoules for several years. They cannot be compared to any other product on the market at the moment. I have tried several other formulations, but none come close to the effectiveness of the 4G. They truly give you the energy your body needs at all levels, and the important thing is that you feel the results immediately. They are definitely a bit pricey, but in the end, they are worth their money!!! An excellent product that I would not only buy again, but I consider it top-notch in its category!

Very good product! My nutritionist recommended them for a strong immune system, strength, and energy. It really works!

It does what it promises! It gives energy, strength, and a strong immune system! My doctor recommended them to me and I take them every year.
