Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.
This Life Extension GEROPROTECT Stem Cell scores 6.1, making it below the site average. It delivers 378mg of Resveratrol, inside the studied range of 150–1000mg with grade C evidence (mostly preclinical, limited human data). At $1.59/day it's among the more expensive options in Autophagy.

Third GEROPROTECT sub-line (distinct from Ageless Cell and Autophagy Renew), targeting stem-cell senescence via garcinol/piceatannol/trans-resveratrol; like the rest of the AI-screened GEROPROTECT family, the mechanism is plausible but backed mainly by cell-line data rather than human RCTs.
