Could become the standard for testosterone boosters
Verified Purchase
I've used a variety of testosterone boosters in the past. While I haven't experienced any significant effects, I feel like they have had some effect. Among them, this product stands out among its peers in terms of the reliability of the brand and the comprehensiveness of its ingredients (it contains everything you need, nothing extraneous). While many people say they don't experience any effects from testosterone boosters, I think this product could be a deciding factor for those who try it and decide not to buy any more products in that category if it doesn't work for them.

As a standardized component, it's a good format, frankly. I haven't started using it yet and am currently updating it.

This is my second jar that I buy, the capsules are small. They are easy to drink. I can't say anything about the effect yet.

testosterone
Verified Purchase
It's great because it contains high-quality ingredients in the right amounts, and the capsules aren't too big. LJ100, in particular, is expensive even when bought alone, but it contains a substantial amount of other effective ingredients, making it a complete testosterone supplement. It's expensive, so buy it when it's on sale!

I used it, three capsules after breakfast. It gives energy. The ingredients are beneficial; if you look at them, you'll immediately know they're good. It's a bit pricey, but it's effective. I'm going to order the same product again now because it's very, very beneficial. It only lasts you about a month, three capsules a day.

Not sure about this but has good ingredients
Verified Purchase
I do believe in the authenticity and cleanness of the product and its ingredients. But just haven't noticed the difference in effect. On the other hand no sickness or side effects. But I do get a gross burp if I don't chug tons of water with it.

The active ingredients used are ones that have been proven effective in research, so I was able to feel some effect.
