B12 also protects the nervous system and without it someone can develop tingling in the hands or feet

Loading vs maintenance dosing protocols Loading phase dosing (Weeks 1-4): Why loading exists: Saturates tissue quickly Builds therapeutic levels fast Front-loads healing response Essential for good results Standard loading: 5mg twice weekly (10mg/week total) Days: Monday and Thursday (or Tuesday/Friday) 3-4 days between injections 4 weeks = 40mg total needed Aggressive loading (serious injuries): 7.5-10mg twice weekly (15-20mg/week) Used by athletes with major injuries Expensive but faster results 4 weeks = 60-80mg total Conservative loading (budget/prevention): 2.5mg twice weekly (5mg/week) Slower tissue saturation Takes longer to see results 4 weeks = 20mg total Maintenance phase dosing (Weeks 5+): Standard maintenance: 2-5mg once weekly Most use 2.5mg weekly Sustains therapeutic levels Continue 4-8 weeks after loading Why maintenance matters: Loading alone insufficient for deep healing Maintenance consolidates gains Prevents reinjury Keeps inflammation down Duration of maintenance: Minimum: 4 weeks Standard: 8 weeks Extended: 12+ weeks for chronic issues Total protocol examples: Standard 12-week protocol: Weeks 1-4: 5mg twice weekly = 40mg Weeks 5-12: 2.5mg once weekly = 20mg Total needed: 60mg (12 vials of 5mg) Cost: $540-$720 Aggressive 8-week protocol: Weeks 1-4: 7.5mg twice weekly = 60mg Weeks 5-8: 5mg once weekly = 20mg Total needed: 80mg (16 vials) Cost: $720-$960 FREE TOOLS FAQ What's the difference between TB-500 loading phase and maintenance phase

Neither approach is inherently better
However, full-length TB-4 is biologically fragile, expensive to synthesize, and has poor shelf stability, making it less practical for research or commercial use

For dosing in your experiments, a U-100 insulin syringe (typically 1 mL, 0.5 mL, or 0.3 mL) is the standard choice due to its fine, easy-to-read unit markings
