Approach: Lab in action. Palette: D, bold color field.

A gloved hand holds a clear petri dish at a slight low angle, close and slightly above eye level, against a saturated tomato-red backdrop. Inside the dish, a thin, translucent layer of pale pink culture medium holds a faint, lacy web of fibroblast cells, with a few small clusters just visible. Hard, clean studio light from the upper left throws a crisp curved shadow of the dish onto the red surface and picks out bright highlights on the rim and the glove's matte white nitrile. In the soft-focus background, a rack of empty microcentrifuge tubes stands out in cool white. One tiny electric green cap on a single tube adds a small accent. The mood is precise and skeptical: a promising result still confined to the dish.

Epithalon je aktivirao telomerazu u stanicama—ali ne kod ljudi

BY HELIX WARD · 16. lis 2026.

Mali četveronačini peptid navodno je aktivirao telomerazu – enzim koji većina odraslih stanica drži u mirovanju – i produljio je telomere u ljudskim stanicama. To je temelj hypea oko epithalona i njegove veze s dugovječnošću. Međutim, eksperiment je proveden na fetalnim fibroblastima u kulturi, a ne na ljudima, pa tvrdnja o produljenju životnog vijeka ostaje samo hipoteza. Evo što je studija iz 2003. zaista pokazala, što izostavlja i kako je pravilno interpretirati prije kupnje.
