Liposomal Glutathione uses a phospholipid delivery system to keep the glutathione from being broken down by stomach acid and allowing it to be absorbed into the bloodstream
Overall, patient accounts convey enthusiasm and satisfaction in many cases, especially when follow-up treatments or proper skincare accompany GHK-Cu

However, I do think B12 injections are much more useful, as this vitamin requires several more steps to absorption

BPC-157 Supports Vascular and Neurological Repair One underappreciated hallmark of long COVID is endothelial dysfunction damage to the lining of blood vessels that impairs circulation, oxygenation, and tissue delivery.7 BPC-157 has demonstrated angiogenic (new blood vessel formation) effects in research models, upregulating VEGFR2 and promoting collateral circulation in ischemic tissue.8 This matters for two reasons: Cardiovascular symptoms (breathlessness, reduced exercise tolerance, tachycardia) may partly reflect impaired tissue oxygenation from vascular damage Neurological symptoms (brain fog, cognitive impairment) may similarly reflect reduced cerebral blood flow BPC-157's neuroprotective effects shown across models of traumatic brain injury, dopamine dysregulation, and serotonin syndrome also suggest value in supporting the neurotransmitter disruption many long COVID patients experience.9 BPC-157 Modulates Inflammation Without Immune Suppression This is critical
