Do not take trametinib for longevity purposes. I worked on synthetic lethal chemo combinations in cancer at a startup for years. We tested this compound and it is not a good idea. The Erk pathway is very important for most epithelial cells. Stick to low risk acarbose and rapamycin combinations and do not consider trametinib. If you have melanoma or another type of solid tumor type then you could consider trametinib. Just trying to prevent you from causing long term damage.
