Some studies suggest its hair-growth performance is comparable to 5 % minoxidil, with fewer side effects
TB-500 complements these effects through its promotion of endothelial cell migration and organization

Normal vital signs (blood pressure, heart rate, respiratory rate, temperature) and body mass index (BMI) between 18 and 30 kg/m 2 Suboptimal vitamin B12 status (deficient to borderline 200300 pg/mL), defined as serum B12 levels within the lower end of the reference range (234894 pg/mL) Able to provide informed written consent Able to comply with study procedures and follow-up visits as outlined in the protocol 2.2.2 Exclusion criteria Known hypersensitivity or allergy to oral vitamin B12 supplements or any of its components Known history of cobalt allergy or sensitivity Severe malabsorption syndromes, including pernicious anemia or intestinal disorders affecting vitamin B12 absorption Current use of acetaminophen, nonsteroidal anti-inflammatory drugs, antibiotics, antacids, proton pump inhibitors (PPIs), multivitamins, or nutritional supplements containing vitamin B12 History of gastric bypass surgery or other procedures that significantly alter GI anatomy or function Significant renal impairment (estimated glomerular filtration rate [eGFR] 0.05) Supplementary Table 1

Vitamin B12 also supports and maintains healthy hair, skin, and nails
This marked it as the first dual GLP-1 and GIP receptor agonist for this purpose
Digestive Support Ironically, while digestive issues can impair B12 absorption, optimal B12 levels support digestive health: Contributes to healthy cell turnover in the digestive tract Supports proper nerve function for digestive processes Helps maintain the health of beneficial gut bacteria Contributes to efficient nutrient processing This creates a positive feedback loop where improved B12 levels enhance digestive function
