Injectable L-Carnitine is a highly bioavailable amino acid compound that helps shuttle fatty acids into your mitochondria to be burned as clean cellular fuel. Unlike oral carnitine—where absorption is low and inconsistent—injectable L-Carnitine bypasses digestion entirely, delivering direct mitochondrial support. It also plays a key role in increasing androgen receptor density in muscle tissue, potentially amplifying your body's response to testosterone and optimizing performance, energy, and fat loss.
