Research Comparison
AOD-9604 vs L-Carnitine (Levocarnitine)
A side-by-side research comparison of AOD-9604 and L-Carnitine (Levocarnitine) drawn from Cedar 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 synthesized from lysine and methionine. It plays a central role in mitochondrial energy metabolism by transporting long-chain fatty acids into mitochondria for beta-oxidation. High-energy tissues such as skeletal muscle, heart, and brain rely heavily on this mechanism. Injectable L-Carnitine provides 100% bioavailability, bypassing the limitations of oral absorption and gut microbiome conversion. It is FDA-approved for the treatment of primary and secondary carnitine deficiency and is extensively studied across metabolic, cardiovascular, and performance-related contexts.
Reading a comparison
A comparison places two records side by side; it does not merge them. Each description above is drawn from that compound's own record, and the two were not necessarily characterised by the same methods, at the same time, or to the same level of detail. Before comparing any attribute, it is worth establishing that both records describe the substance you think they describe — names are not identifiers, and two entries sharing a name can differ in salt form, stereochemistry or the convention used to state a mass. Where a figure carries no method beside it, the comparison is between two reported numbers rather than between two measurements.
