Sterile water for injection contains no preservative, so once the vial is punctured, there is no protection against bacterial growth
It doesn't build muscle, alter hormone levels, or act as a performance-enhancing drug
For a deltoid injection, a five-eighths-inch needle can be enough for a smaller adult, while a larger arm needs a 1-inch needle or longer to be sure the dose reaches muscle

**Quick calculator (30mg vial at 10mg/ml):** | Weekly Dose | Volume per Injection | Syringe Units | Doses per Vial | |------------|---------------------|---------------|----------------| | 1mg | 0.10ml | 10 units | 30 doses | | 2mg | 0.20ml | 20 units | 15 doses | | 4mg | 0.40ml | 40 units | 7.5 doses | | 8mg | 0.80ml | 80 units | 3.75 doses | | 12mg | 1.20ml | Split: 60 units x2 | 2.5 doses | ## Universal Mixing Calculator Use this formula for any vial size and desired concentration: **BAC Water (ml) = Vial Size (mg) Desired Concentration (mg/ml)** **Injection Volume (ml) = Desired Dose (mg) Concentration (mg/ml)** **Syringe Units = Injection Volume (ml) 100** ### Example Calculation You have a 50mg vial and want 10mg/ml concentration: - BAC water: 50mg 10mg/ml = 5.0ml - For a 4mg dose: 4mg 10mg/ml = 0.4ml = 40 units - For an 8mg dose: 8mg 10mg/ml = 0.8ml = 80 units ## Which Vial Size Should You Choose

TB-500 research mechanisms Published research on TB-500 and full-length Thymosin Beta-4 has investigated: Actin sequestration Thymosin Beta-4's role binding G-actin and modulating cytoskeletal dynamics in cellular research Cell migration effects on keratinocyte and endothelial cell migration in tissue-repair research Anti-inflammatory pathways modulation of inflammation in injury-research models Cardiac myocyte research effects on cardiac cell behaviour in heart-injury research models (much of this work via RegeneRx-sponsored research) Hair follicle research effects on follicle-related cellular pathways in research models The published literature is broader than BPC-157's in terms of independent research groups but with smaller volume of compound-specific work versus the mechanism-focused work on full Thymosin Beta-4
