What is thymalin?

Thymalin is a peptide mix taken from calf thymus (a gland in the chest that trains immune cells). It has been used by doctors in the Soviet Union and Russia since the 1980s, and there is a lot of Russian medical writing behind it. That includes a group followed for 6 to 8 years, which reported roughly twofold lower death rates in those treated, and a 92-patient COVID-19 study where everyone knew what they were getting. This site's review found 8 studies for it, 4 of them in people, and none repeated by research groups outside that school.
