Peptides of pineal gland and thymus prolong human life
Khavinson VKh, Morozov VG. Neuro Endocrinology Letters 2003;24:233-240.
What it found
Tested epithalamin (a pineal gland extract) and thymalin (a thymus extract), not synthetic epitalon. The authors reported fewer respiratory infections and lower death rates in treated elderly people than in controls.
Limitations
Did not use epitalon. PubMed indexes it as a randomised trial, but the abstract does not describe randomisation, blinding or doses. From the Khavinson group; not independently replicated.
