What is the difference between AOD-9604 and Carnosine?

AOD-9604: AOD-9604 stimulates lipolysis and inhibits lipogenesis through mechanisms believed to be independent of the insulin-like growth factor pathway. Carnosine: Dipeptide that buffers lactic acid in muscle during high-intensity exercise; chelates metal ions; prevents and reverses protein glycation; scavenges aldehyde oxidative byproducts

Is Carnosine FDA approved?

Carnosine is not evaluated or approved by the FDA. It is discussed for research and educational purposes only, not as medical guidance.

How is AOD-9604 administered in research settings?

In research settings, AOD-9604 is typically administered via the subcutaneous or oral routes. PeptideBase does not provide dosing or administration instructions.

How is Carnosine administered in research settings?

In research settings, Carnosine is typically administered via the oral, intravenous, or topical routes. PeptideBase does not provide dosing or administration instructions.

About AOD-9604

AOD-9604 stimulates lipolysis and inhibits lipogenesis through mechanisms believed to be independent of the insulin-like growth factor pathway. It appears to mimic the fat-metabolising action of growth hormone without triggering the proliferative effects associated with full GH or GH-releasing peptides. Oral bioavailability has been observed in some formulations, making it of interest for non-injectable protocols.
