“L-carnitine helps your body burn long chain fatty acids... I take 2 pills in the morning and 2 before a cardio workout to get an endurance boost.”

“yeah i helps burn fat if you take it before bed but it also gives you energy so i makes it a bit difficult to sleep for me at least”
“I inject 1g of l-carnitine every single day, and it's been great for fat loss, energy and mental alertness. ... carnitine didnt do shit for me plus it reeks of fish”
