Thymosin Beta-4 (TB-500) is a synthetic peptide analog of the naturally occurring Thymosin Beta-4. It is widely discussed and used in research and performance enhancement contexts for its purported benefits in tissue repair, healing, inflammation reduction, and improved flexibility. Unlike pharmaceutical drugs with standardized dosages, TB-500 is often used off-label, and dosage recommendations can vary.
How the TB-500 Dosage Calculator Works
This calculator helps users estimate the volume of liquid to draw from a TB-500 vial based on their body weight, a desired dosage per kilogram, and the concentration of the TB-500 solution. The calculation involves two main steps:
Calculate Total Desired Dose: First, we determine the total amount of TB-500 needed. This is done by multiplying your body weight in kilograms by the desired dosage per kilogram. For example, if you weigh 75 kg and aim for a dosage of 5 mcg/kg, your total desired dose would be 75 kg * 5 mcg/kg = 375 mcg.
Calculate Volume to Draw: Next, we convert the total desired dose (in micrograms) into a volume (in milliliters) based on the concentration of the TB-500 vial. Since vial concentrations are typically given in milligrams per milliliter (mg/mL), we need to ensure our units are consistent. A common conversion is 1 mg = 1000 mcg.
For instance, if you need 375 mcg and your vial is concentrated at 5 mg/mL:
Volume (mL) = (375 mcg / 5 mg/mL) / 1000 mcg/mg
Volume (mL) = 75 mcg/(mg/mL) / 1000 mcg/mg
Volume (mL) = 0.075 mL
Typical Dosage Ranges and Considerations
Dosage for TB-500 can vary significantly based on individual goals, experience, and response. Common protocols often suggest:
Loading Phase: Higher doses might be used initially (e.g., 2-5 mg, 2-3 times per week) for a few weeks.
Maintenance Phase: Lower doses might be used less frequently (e.g., 1-2 mg per week or every other week) for ongoing support.
Important Notes:
The calculator provides an estimate based on the inputs provided.
Always ensure you are using sterile techniques when preparing and administering peptides.
Consult with a qualified healthcare professional or an experienced peptide user before starting any new regimen, especially regarding dosage and administration.
TB-500 is not approved by the FDA for human use and is sold for research purposes only.
