DL-Cysteine-d₁ 

DL-Cysteine-d₁ is the deuterated labeled 2-Amino-3-mercaptopropanoic acid (HY-W012850). 2-Amino-3-mercaptopropanoic acid is a cysteine derivative^[1][2].

Amino acids and amino acid derivatives have been commercially used as ergogenic supplements. They influence the secretion of anabolic hormones, supply of fuel during exercise, mental performance during stress related tasks and prevent exercise induced muscle damage. They are recognized to be beneficial as ergogenic dietary substances^[1].
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[2].
