The Alpha-1 Antitrypsin that rPeptide sells online is sourced from human plasma and must be stored at minus 20 degree Celsius, according to the company’s website. The company also advises that this protease inhibitor be utilized solely for research, not in humans. WebMD details that Alpha-1 Antitrypsin is a protein found in the lungs and bloodstream that helps protect against emphysema and chronic obstructive pulmonary disease (COPD). Although rare, a deficiency in Alpha-1 Antitrypsin can increase the likelihood of developing emphysema and at a much younger age, from 30 to 40 years old. This deficiency is caused by a mutation of the gene that tells the body how much Alpha-1 Antitrypsin to make. The good news is that most mutations of this gene do not cause problems and to have a serious Alpha-1 Antitrypsin deficiency, an individual must inherit the mutated gene from both parents.
