What is the difference between AOD-9604 and PEG-MGF?

AOD-9604: AOD-9604 stimulates lipolysis and inhibits lipogenesis through mechanisms believed to be independent of the insulin-like growth factor pathway. PEG-MGF: Pegylated form of MGF; activates muscle stem cells (satellite cells) to repair and regenerate muscle tissue after damage

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 PEG-MGF administered in research settings?

In research settings, PEG-MGF is typically administered via the subcutaneous or intramuscular 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.
