It is 15 amino acids long, which makes it large enough to have meaningful receptor interactions but small enough to synthesize cost-effectively
The secondary outcomes will be the serum vitamin B12 concentration (pg/ml), adverse events (description, moment of onset and resolution, intensity, cause, steps taken), adherence to treatment (measured at each patient visit via the number of vials used for patients in the oral arm, and the number of injections given in the intramuscular arm), quality of life (measured using the EuroQoL-5D questionnaire), and patient satisfaction and preferences
Such models allow scientists to dissect the molecular pathways, potentially involving integrin signaling and cell adhesion molecules, that GHK-Cu may modulate to support neuronal structures in a controlled culture environment
Lumbar sympathetic block (in the lower back): Helps chronic back, leg, or foot pain caused by conditions such as reflex sympathetic dystrophy, regional pain syndrome, vascular insufficiency, and peripheral neuropathy
The company recommends 500mcg once daily orally
If the B12 shot is painful, then your muscles impulsively flex as a reaction to the needles insertion
