1. 12.5 lbs 125 x .10 = 12.5
2. I build my muscles mass up and refined my body with Xtreme NO, a supplement combination of proprietary ingredients with a online fitness program that will deliver enhanced performance like never before. Xtreme NO contains an advanced L-Arginine blend of amino acids that cause an increase in the levels of nitric oxide (NO) in the body that helps to move oxygen into your muscles where they need it the most, sparking powerful muscle growth, strength gains, and incredible ripped muscles.
