TB-500 Dosage Calculator

Calculate exact TB-500 injection volumes. Pre-filled for a 5mg vial with 2ml BAC water (2,500 mcg/ml). Typical 2mg dose = 80 units.

Dose Reference Table

Pre-calculated for a 5mg vial + 2ml BAC water = 2,500 mcg/ml concentration. Using a 100-unit (1ml) insulin syringe.

Dose Inject Volume (ml) Syringe Units
500mcg (0.5mg) 0.200 ml 20 units
1000mcg (1mg) 0.400 ml 40 units
1500mcg (1.5mg) 0.600 ml 60 units
2000mcg (2mg) 0.800 ml 80 units
2500mcg (2.5mg) 1.000 ml 100 units
4000mcg (4mg) 1.600 ml 160 units

About TB-500

TB-500 is a synthetic version of Thymosin Beta-4 (Tβ4), a naturally occurring peptide found in high concentrations in blood platelets and other tissues throughout the body. It is one of the most studied healing peptides in research settings, with a broad range of potential regenerative applications.

TB-500 is thought to work primarily by promoting actin polymerization, which is essential for cell migration and tissue repair. Research has explored its role in healing muscle, tendon, ligament, and skin injuries, as well as potential cardiac and neurological protective effects.

TB-500 is typically supplied in 5mg vials. Using 2ml of bacteriostatic water gives a concentration of 2,500 mcg/ml. A typical loading dose of 2mg (2000mcg) requires 0.8ml — or 80 units on a 100-unit insulin syringe. Maintenance doses are often lower, around 1–1.5mg twice weekly.

TB-500 has a longer half-life than BPC-157 ("several days"), which is why it is typically dosed twice weekly rather than daily. It is often combined with BPC-157 in a blend for synergistic healing effects.

Frequently Asked Questions

Common research protocols use a loading dose of 2–4mg twice weekly for 4–6 weeks, followed by a maintenance dose of 2mg twice weekly. For 5mg + 2ml BAC water (2500 mcg/ml), 2mg = 0.8ml = 80 units.
2ml of bacteriostatic water for a 5mg TB-500 vial is the standard, giving 2,500 mcg/ml concentration. For a 10mg vial, use 4ml to maintain the same concentration.
With 5mg + 2ml BAC water (2500 mcg/ml): 2mg = 2000mcg ÷ 2500 mcg/ml = 0.8ml = 80 units on a 100-unit syringe.
Research protocols typically use a loading phase of 2–4mg twice weekly for 4–6 weeks, then a maintenance phase of 2mg per week or every other week. Always work with a healthcare professional.
Given its half-life of several days, TB-500 is commonly injected twice weekly during a loading phase, and weekly or biweekly during maintenance. This differs from BPC-157 which is typically dosed daily.
