A low-grade inflammation caused by obesity leads to its many inflammation-associated complications, including insulin resistance, type 2 diabetes, accelerated atherosclerosis, nonalcoholic steatohepatitis that can lead to liver cirrhosis, heart failure, cancer, and Alzheimers disease
By boosting your metabolism, B12 shots can aid in weight management and overall metabolic health
Hepatocellular injury, meaning damage to liver cells, releases stored vitamin B12 into the blood, and chronic liver disease reduces the clearance that normally keeps levels in check

Common side effects by peptide type Growth hormone peptides: Water retention (temporary) Lethargy initially (adapts within weeks) Carpal tunnel symptoms (rare, high doses) Insulin resistance (monitor with long-term use) IGF-1 LR3: Hypoglycemia (keep fast carbs on hand) Jaw/facial bone growth (with chronic use) Organ enlargement (long-term misuse) Healing peptides: Minimal side effects Occasionally: fatigue, headache (rare) Monitoring and bloodwork Baseline testing before starting: IGF-1 levels Thyroid panel (T3, T4, TSH) Fasting glucose and insulin Lipid panel Liver and kidney function Follow-up testing: Every 3-6 months during protocol Monitor IGF-1 (ensure not excessively elevated) Check glucose metabolism Liver/kidney function Contraindications Avoid peptides if: Active cancer (GH/IGF-1 can promote tumor growth) Diabetic without physician oversight Significant organ disease Use caution if: Family history of cancer Pre-diabetic Taking medications that affect blood sugar See our peptide safety and risks guide for comprehensive safety information
