The GLP-1RAs are peptide-based therapies and therefore, such as insulin, require subcutaneous injection to avoid degradation by gastrointestinal enzymes
Administered directly into muscle tissue, B12 injections bypass the need for absorption in the gastrointestinal tract, making them a highly effective method for increasing B12 levels in the body
Body aches are not a marker of medication efficacy
And they still get excellent outcomes
However, you should remain vigilant for warning signs such as a fecal-like smell, persistent vomiting, or severe abdominal pain, as these may be linked to bowel obstruction
