L-Carnitine is the amino-acid derivative that moves long-chain fatty acids into the mitochondria so they can actually be burned. The research draw is exposure: the guide reports 5-10x higher plasma levels for this preparation than for supplement intake, which is why it shows up in fat-oxidation and exercise-performance work. Supplied as 600 mg and 1200 mg vials.

- Essential for mitochondrial fatty acid transport, carrying long-chain fats across the inner membrane via the CPT1/CPT2 carnitine shuttle.PubMed: L-Carnitine
- The guide reports exercise-performance and fat-utilization improvement within 2-4 weeks, along with reduced post-workout fatigue.Peptide Guide p.59
- Works best in a caloric deficit or alongside GLP-1 therapy, and is stacked with lipotropic blends and NAD+ in mitochondrial protocols.Peptide Guide p.59
- Reported as generally well tolerated; the noted effect is a fishy odor from TMAO conversion.Peptide Guide p.59
