L-Carnitine vs AOD9604: What’s the Difference?
The main difference between L-Carnitine and AOD9604 is mechanism: L-Carnitine is studied for mitochondrial fatty-acid transport research — Acts as a cofactor for carnitine palmitoyltransferase I (CPT-1), enabling long-chain fatty acid entry into the mitochondrial matrix. AOD9604 is studied for lipolysis without gh side-effects — Modified C-terminus fragment of HGH.

| In plain English | Think of carnitine as the bus that takes fat into the mitochondria so it can be burned for energy. | AOD9604 isolates the fat-burning effect of growth hormone without the muscle-building or blood-sugar effects. |
| How it works | Acts as a cofactor for carnitine palmitoyltransferase I (CPT-1), enabling long-chain fatty acid entry into the mitochondrial matrix. | Stimulates lipolysis and inhibits lipogenesis without significant effect on IGF-1, insulin sensitivity, or glucose. |
| Researchers study | Endurance performance, fat oxidation, cardiac function, and male fertility. | Obesity, body composition, and osteoarthritis (intra-articular use). |
| Internet discussion | Discussed in fat-loss and endurance circles; injectable form popular in research talk. | Discussed for targeted fat loss. |
