Leucine:
Regulates and improves muscle protein synthesis after exercise.
BCAAs:
Branch Chain Amino Acids help your body protect its glycogen stores. This lets you burn fat while increasing performance and endurance.
L-Lysine:
Lysine works with other essential amino acids to maintain growth, lean body mass, and the body's store of nitrogen.
L-Arginine:
Provides nitrogen used to make nitric oxide (NO) and increase blood flow to tissue during and after exercise. NO promotes fat breakdown, suggesting that arginine may help with the utilization of body fat stores during exercise or when dieting for fat loss.

Warm and comfy thermal wear
Size: Small, Color: Navy
They are very soft, don't ride up. Clothes do not stick to them like other thermals do. The fit is perfect. They are warm and comfy. The quality is good, too.

I bought these as a gift for my friend who lives in cold country and she says she loves them and they wash-and-wear well and are well made. Also very warm. Very comfortable and the fit is right on size. I would order them again

Perfect
Size: Large, Color: Navy
Oooooo these are so nice and soft and so warm! I am a nurse and work in an old hospital that is getting remodeled and there have been days we haven’t had heat and I have been very happy that I purchased these. My scrubs glide very nicely over these and don’t add any bulk. Definitely worth every penny! The fit is spot on and they wash up really well.
