Safety Profile Across all six human trials and the extensive preclinical work, the safety picture is quite clean: No serious adverse events attributed to the compound No effect on IGF-1 No impairment of glucose tolerance or insulin sensitivity No genotoxic activity Most common side effects: mild injection site irritation, occasional headache or fatigue all transient This is genuinely one of the better-characterized peptides from a safety standpoint, largely because it actually went through a formal development process with proper clinical oversight
Evidence from RCTs for the use of B12 in other types of neuropathies is scarce, although non-randomised/uncontrolled studies have shown some benefits

It is used in scientific and analytical research environments to prepare, dilute, or reconstitute peptide and protein solutions
Additionally, PRP contains anti-inflammatory mediators that may help regulate the inflammatory environment, potentially alleviating pain and slowing degenerative changes in the intervertebral disc [12], [21]
For patients who experience a paradoxical decrease in energy levels, it doesnt mean you should stop taking the B12 but instead decrease your dose by half (so take 2,500mcg every 7 days) or simply take 5,000mcg every 14 days instead
