It's an okay product and definitely has some benefit, but the quality doesn't match the price. Tongkat ali is the ingredient is what I'd mostly like it to have more of. Hubermanlab recommends 500 mg daily dose, these have 100 mg with recommended dosage. Taste and smell have somewhat liquerice quality and size in easy to swallow.
It does something in terms of 'energy', however the effects on me are quite mild. For this reason I stopped taking it regularly(did it for 10 days), but I still do occasionally... I did not have any blood test done, so I cannot say about measurable testosterone increase.
