A potential benefit of L-carnitine in these patients is based on the fact that it can (i) increase the oxidation of long-chain fatty acids which accumulation may contribute to insulin resistance in skeletal muscle, and (ii) enhance glucose utilization by reducing acyl-CoA concentration within the mitochondrial matrix (see Biological Activities) (42)
On the other hand, injections might be better for joint and muscle health since you apply the BPC-157 peptide near the places where you need site-specific support, be it a joint or soft tissue
Medical approval: In 2019, the FDA approved PT-141 under the trade name Vyleesi for treating hypoactive sexual desire disorder (HSDD) in premenopausal women
That near-parity underpins the prevailing model of this copper peptide as a physiological copper shuttle rather than an inert chelator, and a ternary GHK-Cu-albumin complex has since been characterised directly

This phase establishes tissue exposure to the peptide without overwhelming the signaling pathways
