Users should assess progress through objective measurements (body composition analysis, circumference measurements, progress photos) rather than scale weight alone, as fat loss may be accompanied by muscle preservation or gain

Vitamin B12 injections can be given in three ways: into the muscle (intramuscular), under the skin (subcutaneous), or through a vein (intravenous)
Human studies have mainly focused on safety, how the body handles the peptide, and metabolic markers such as IGF-1 and glucose levels, but have not shown strong evidence of weight loss
Since it is injected, it does not rely on your digestive system to be absorbed, making it highly effective regardless of your diet, though eating foods rich in vitamin B12 can help support your long-term recovery
