Epitalon 3 mg is a tetrapeptide that can reactivate telomerase production in cells, repair telomeres, and rejuvenate the whole body. Telomeres are found at the tips of DNA strands and prevent the loss of genetic information resulting from the chromosome-shortening which occurs with each cell division. Progressive telomere shortening is closely linked to many age-related diseases and is also predictive of early mortality in elderly subjects. If telomerase could be activated, cells could potentially exceed their critical ‘time limit’ and continue to replicate, avoiding one of the more apparently inevitable mechanisms of ageing. Epitalon is a major advance in anti-aging research and has been shown to increase the lifespan of rats by 25%.
