Research Comparison
AOD-9604 vs L-Carnitine (Levocarnitine)
A side-by-side research comparison of AOD-9604 and L-Carnitine (Levocarnitine) drawn from Cobalt Peptides' peptide database records.
AOD-9604
AOD-9604 is a modified 17-amino acid fragment derived from the C-terminal region of human growth hormone (hGH 176–191), with the addition of an N-terminal tyrosine residue. It was specifically engineered to isolate the lipolytic and anti-lipogenic properties of growth hormone while avoiding its anabolic and endocrine effects. Unlike full-length hGH, AOD-9604 does not bind to the growth hormone receptor, does not elevate IGF-1 levels, and does not impair glucose metabolism. This selective mechanism has made it a focus of research in obesity, fat metabolism, and cartilage repair, offering a more targeted metabolic profile without the systemic hormonal effects associated with growth hormone.
L-Carnitine (Levocarnitine)
L-Carnitine (levocarnitine) is a naturally occurring amino acid derivative synthesised from lysine and methionine. It has a central role in mitochondrial energy metabolism, transporting long-chain fatty acids into the mitochondrion for beta-oxidation — a mechanism that high-energy tissues such as skeletal muscle, heart and brain depend on. Injectable preparations bypass the absorption and gut-conversion limits of oral dosing. Licensed medicines containing levocarnitine exist and are prescribed by clinicians; the material supplied here is a research compound and is not one of them.
