Have noticed a change in my energy level after taking for several weeks now. Workouts are easier and I can defiantly see the the muscle development. I'm older (60) and I knew it would take time, but good product.
Four pills provide 1.6 g of leucine. I would have to take 8 pills a day to get my needed 3g/day dosage. Will probably look for another product once I've used this up.
I meant to order the powder, but mistakenly ordered the capsules. I just open them up and add to my protein shake. Next time I will order correctly and get the powder. I read that extra leucine can help in gaining more muscles, so we will see.
I always have more energy and just feel generally better when I take it, which I do daily

NutraBio. NUTRABIO L-LEUCINE FREE FORM AMINO ACID SUPPLEMENT HPLC LAB TESTED FOR POTENCY Leucine is thought to be the most effective BCAA for preventing the body's burning of muscle stores for energy during intense workouts because it is converted to glucose more quickly than isoleucine and valine. L-Leucine is an essential amino acid, meaning it cannot be made by the body, and must be acquired through food or dietary supplements. Leucine is classified as a branched-chain amino acid (BCAA). It comprises about 8% of the total amino acid count in your body's protein structures and is the fourth most concentrated amino acid in skeletal muscle tissue. L-Leucine stimulates muscle protein synthesis and may be the major fuel involved in anabolic (tissue building) reactions. This makes them especially important for body builders and other athletes in sports that demand explosive strength.
