Excellent
Xtreme L-Carnitine does its job very well. The liquid version is quite pleasant and the taste is not at all cloying. It's super easy to take and gives that energy boost. Excellent value for money compared to other brands on the market.

Spectacular
The best Carnitine I've bought so far. The taste is excellent. You'll notice the bloating disappearing after the first few doses. You should definitely see a significant reduction in weight in the coming days. I recommend it.

Very good!
Good carnitine, I've preferred the liquid version for a long time, I notice the effect more. To me, it seems to be the same as Gold Nutrition's but at a better price. I recommend it!

I recommend
Of all the L-Carnitine supplements I've tried, this is by far the best. During longer cycling workouts (over 3 hours), exhaustion comes later. Abdominal definition seems more evident. After 1 month of taking it and training every day, I lost 6 kg.

Magnificent!
You know that little bit of fat in your abdominal area that you think you'll never lose?! I lost it, I gained a lot of abdominal definition, after very intense workouts and plenty of daily cardio. One package = 1 month and it works perfectly. If necessary, I'll use it again! Congratulations!
