He continued to say that for people with B12 deficiency, parenteral supplementation (ie not through the mouth/digestive system) therefore is a useless and expensive treatment, and if you still want it the NHS should not pay for it, you should pay for it yourself
Comparing Results: What Real People Experience While everyone responds differently, heres a general idea of what to expect: Vitamin Injections Faster symptom relief (often within days) Consistent energy and focus Noticeable improvements in skin and hair Immune support during cold and flu season Oral Supplements Gradual changes over weeks or months May require trial and error to find the right brand/dose Lower cost but less predictability Dependent on daily compliance Supplement Absorption: What Science Says Multiple studies support the idea that nutrient absorption from injections is superior to oral intake
What sets GHK-Cu apart in the research literature is scale: naturally occurring levels of the peptide in human plasma decline from roughly 200 ng/mL at age 20 to about 80 ng/mL by age 60, a drop researchers have used as a starting point for studying its potential connection to age-related changes in tissue repair
While its natural counterpart plays a role in gut health and epithelial repair, the synthetic version has demonstrated far-reaching regenerative properties particularly in soft tissues like tendons, ligaments, and muscle fibers
That's the real problem
