Indirect Calorimetry and Respiratory Exchange Ratio Indirect calorimetry estimates energy expenditure and substrate use from oxygen consumption and carbon-dioxide production
A good next step is to see if you qualify for a personalized GLP-1 program, especially if you want support with dosing, follow-up, and routine questions
Unlike other treatments injected into the veins, B12 shots are administered into the muscles to avoid losing a huge amount when the person passes urine
Product quality is a major and underappreciated risk unregulated 'research' vials can contain impurities, endotoxins, or incorrect dosages

Example: 180lb person (82kg) for injury recovery at 5 mcg/kg: 82kg 5mcg = 410mcg per day With 5mg vial + 2ml water = 2,500mcg/ml concentration Draw 0.16ml per injection 12 doses per vial HOW For injury recovery (sprains, tears, tendonitis): Dose: 400-600mcg per day Frequency: Split into 2 doses (morning and evening) Duration: 4-6 weeks minimum Injection site: Near injury OR systemic (abdomen) Results timeline: 2-3 weeks to notice improvement For gut health (IBS, leaky gut, ulcers): Dose: 200-400mcg per day Frequency: Once daily, preferably morning on empty stomach Duration: 6-12 weeks Injection site: Systemic (abdomen) Results timeline: 3-6 weeks For general wellness and prevention: Dose: 150-300mcg per day Frequency: Once daily Duration: Ongoing or 4-week cycles with 2-week breaks Injection site: Systemic (abdomen) Results timeline: Subtle, cumulative benefits Body weight-based dosing: 150 lbs (68kg): Low: 204mcg (3 mcg/kg) Medium: 340mcg (5 mcg/kg) High: 476mcg (7 mcg/kg) 180 lbs (82kg): Low: 246mcg (3 mcg/kg) Medium: 410mcg (5 mcg/kg) High: 574mcg (7 mcg/kg) 200 lbs (91kg): Low: 273mcg (3 mcg/kg) Medium: 455mcg (5 mcg/kg) High: 637mcg (7 mcg/kg) Start at the low end for your goal

Unlike preservative-free sterile water, which is intended for single-use laboratory applications, bacteriostatic water for injection is designed to support multi-dose access in controlled research settings
