— Overview

Metformin ER at a glance.

Metformin improves insulin sensitivity, lowers fasting glucose, and is studied for longevity outcomes (TAME trial). Commonly stacked with GLP-1 protocols or as a standalone metabolic optimizer.

— From the clinic

Peptides aren't a substitute for the protocol around them. We design dose, cycle, and stack against your labs and your goals — not a generic vial in a drawer.
