    Good product. It suppreses my appetite and helps me burn more calories quicker on my workout days. Most importantly, I don't get the jitters or a mild headache like other products I've tried. I'd definitely recommend this to anyone.

    Awesome product!! I received this last week and have been using it everyday. I have noticed a difference in my waistline, already one belt hole down!! I haven't changed my diet and it has helped me get past my plateau. I tend to become tired by mid afternoon, however with this not only is my focus better, but I have maintained energy throughout the day. I didn't notice any jitters and felt fine, so I think they got that right when making this. I've tried many fat burners and I'd have to say this is my favorite so far!

    I've never had to much of a problem with weight, but lately my genetics apparently stopped working and gained a few unwanted pounds. Needless to say lean genes is the route I went and couldn't be happier! I can see my abs again

    I've been taking Lean Genes for a little over a month now and the results are amazing. I don't normally post reviews unless a product deserves it but I have to say this is the best fat burner I have used. Just 30 minutes after taking these pills I feel a warm sensation go over my body followed by sustainable energy with no crash! My appetite feels suppressed and in just one month I've already seen significant fat loss. I use these in the morning and then the pre workout later in the evening with no problems at all. Absolutely love it!

    I recently became vegan and have had some trouble finding vegan supplements. I contacted the company and got a very quick response with ingredients etc. I had lost a lot of weight but hit a plateau and this fat burner helped me get past that and lose those extra pounds! It also has caffeine in it which is always a plus! This pills are easy to swallow and don’t get stuck in your throat :) 10/10 would recommend

    I started using this product as part of a supplement/diet plan my fitness coach created. I noticed after a few days that I felt more energized, never tired, and generally in good moods. When I needed to replace them, they were all sold out and I was forced to by a different brand. I felt an immediate change in every aspect of my body/life. I started checking regularly and the second these were back in stock, made sure to buy them. Combined with my workout schedule, I have seen such a transformation in my body and mood and I can not be happier. These are the best fat burners that I have used and will continue to use them.
