Class / typeAMPK activator / exercise mimetic (research compound)
CategoryMetabolic & Weight
Status (Jul 2026)Research use only

How it works

As an AMP analog, it activates AMP-activated protein kinase (AMPK), promoting glucose uptake, fatty acid oxidation, and mitochondrial biogenesis in muscle.

Known / used for

Used in metabolic, exercise-physiology, and cancer research; studied as a potential endurance and metabolic enhancer in animals.

Positives

In animal studies it increased endurance and fat oxidation without exercise, earning the label 'exercise in a pill' among researchers.

Negatives & risks

Human safety and efficacy are unestablished, it can cause metabolic and cardiovascular strain, and it is banned in competitive sport.
