I have bought this product have often and repeatedly used over time for 6 months. I can say with 100% certainty that L-carnitine positively engages in fat metabolism, as long as you exercise regularly operates. There are nunmal no miracles capsules that melt the fat without exercise! However, the intake should be approximately 1 to max. Be taken 2 hours before exercise. On non-training days at about the same time as on training days. I myself have experienced that with concurrent use of L-carnitine and sports the weight reduction of equip goes faster than without. For me an absolute buy recommendation!
