Supplementing amino acids in an isolated form, like with L-cysteine is not such a good idea coz of the thyroid inhibiting effects according to RP:
“Muscle protein is very rich in tryptophan and cysteine, and these amino acids suppress the thyroid gland’s function, and are potentially toxic to nerves, especially in the presence of cortisol and hypoglycemia. Tryptophan is turned into serotonin, which promotes lipid peroxidation, blood clotting, and certain patterns of nerve activity. Serotonin can suppress mitochondrial respiration, and along with the reduced body temperature that it produces, a pattern or torpor or helplessness tends to be produced.” -Ray Peat, PhD
“The selection of amino proteins should minimize the amino acids tryptophan (which is the precursor to serotonin) and cysteine (which like tryptophan, suppresses thyroid function), by including gelatin and fruits. Gelatin is 22% glycine, which protects the lungs and other organs against toxins and inflammatory agents, and many fruits are also “deficient” in tryptophan and cysteine.” -Ray Peat, PhD
