Dosing for TB 500: TB-500 Dosage Calculator for Reconstitution and Syringe Units

TB-500 Reconstitution Calculator

Convert TB-500 amounts into millilitres and units on a U-100 insulin syringe for any vial size and water volume. The calculator is set to our TB-500 10mg vial.

Reconstituting TB-500

TB-500 amounts are usually written in milligrams rather than micrograms, so the volumes involved are larger than for BPC-157. With a 10mg TB-500 vial and 2 mL of bacteriostatic water, the solution is 5 mg per mL and a full 1 mL syringe holds 5 mg. If a calculation shows more than 100 units, the volume is larger than a 1 mL syringe holds.

TB-500 is often studied alongside BPC-157; see the blend calculator for the two in one vial, and our guide to BPC-157 vs TB-500.

TB-500 reconstitution chart

Concentration for each vial size and water volume. On a U-100 insulin syringe, 10 units is 0.1 mL and 100 units is 1 mL.

Vial	Bac water added	Concentration	Per 10 units (0.1 mL)	Per 1 unit
5 mg	1 mL	5 mg/mL	0.5 mg (500 mcg)	50 mcg
5 mg	2 mL	2.5 mg/mL	0.25 mg (250 mcg)	25 mcg
5 mg	3 mL	1.667 mg/mL	0.167 mg (166.667 mcg)	16.667 mcg
10 mg	1 mL	10 mg/mL	1 mg (1000 mcg)	100 mcg
10 mg	2 mL	5 mg/mL	0.5 mg (500 mcg)	50 mcg
10 mg	3 mL	3.333 mg/mL	0.333 mg (333.333 mcg)	33.333 mcg

The formula behind the calculator

concentration (mg/mL) = TB-500 in vial (mg) ÷ water added (mL)

units on a U-100 syringe = amount (mg) ÷ concentration (mg/mL) × 100

Amounts in micrograms are divided by 1,000 first. The calculator does this arithmetic only; it does not recommend an amount, and TB-500 from AminoBlend is supplied for laboratory research use only.

Shop TB-500 Online After You Plan the Dilution

The TB-500 10mg vial sells for $79, and the maths above assumes exactly that fill. Buy it online alongside a 3 mL bac water vial and the numbers on this page carry straight onto the bench. Labs that pair it with BPC-157 can compare the Wolverine Blend before ordering. No local stockist near me needed: every lot is in the COA library.

Dosage for TB500 in Lab Terms

Searches for dosage for TB500 usually want a human figure, which we do not publish. What this page gives is the laboratory version: how much TB-500 sits in each 0.1 mL of a reconstituted 10mg vial at the water volume you choose, and the matching U-100 mark. Buy the TB-500 10mg vial online once the concentration suits the study.

TB-500 Calculator Explained

What Each TB-500 Result Line Tells You

Concentration in mg/mL is the 10mg TB-500 fill divided by the water you put in. Multiply it by 100 and you get the micrograms held in 0.1 mL, which is the stretch from zero to 10 units on a U-100 syringe. The volume line shows how many millilitres hold your milligram target, and the units line is that same volume read off the syringe scale, 100 units per mL.

TB-500 10mg Vial: A 1.5 mg Target at Three Water Volumes

1 mL: 10 mg/mL, 1,000 mcg per 0.1 mL, and 1.5 mg occupies 0.15 mL, or 15 units.
2 mL: 5 mg/mL, 500 mcg per 0.1 mL, and 1.5 mg occupies 0.3 mL, or 30 units.
3 mL: 3.333 mg/mL, about 333 mcg per 0.1 mL, and 1.5 mg occupies 0.45 mL, or 45 units.

Keeping Milligram TB-500 Targets Inside One Syringe

Because TB-500 targets are usually written in milligrams, the risk is running past the 100 unit mark rather than squinting at tiny volumes. A 4 mg aliquot from a 10mg vial made up with 3 mL needs 1.2 mL, or 120 units, which a 1 mL syringe cannot hold in one draw. Using 1 or 2 mL of water keeps larger TB-500 amounts on a single barrel, while 3 mL only pays off for fractions of a milligram.

Which TB-500 Sequence Sets the Molar Figure?

The TB-500 name is used for more than one sequence, from full thymosin beta-4 at roughly 4,963 g/mol to much shorter fragments built around the LKKTETQ region. The same 5 mg/mL stock therefore has very different molarity depending on which structure your lot actually is. Read the identity and mass on the certificate for your lot before converting micromolar targets, and see what TB-500 is for the background on these variants.

TB-500 Calculation Errors to Check For

Typing 1.5 into the mcg field: the calculator then returns 0.03 units instead of 30 at 5 mg/mL.
Reading 30 units as 30 mL, a hundredfold error; 30 units is 0.3 mL.
Mixing TB-500 with BPC-157 in one vial yourself and then entering only the TB-500 fill; the blend calculator covers a combined vial.
Topping up a TB-500 10mg vial with extra water later but leaving the original volume in the calculator; the total liquid in the vial is what counts.

TB-500 Calculator Questions

How much bac water to reconstitute 10mg TB-500?

1 to 3 mL in a standard vial. 2 mL gives 5 mg per mL, so 10 units on a U-100 syringe holds 0.5 mg. Less water gives a stronger solution and smaller volumes.

How many units is 2mg of TB-500?

At 5 mg per mL, 2 mg is 0.4 mL, which is 40 units on a U-100 syringe. At 3.33 mg per mL (10mg in 3 mL) it is 0.6 mL, or 60 units.

Does TB-500 dissolve in bacteriostatic water?

Yes. TB-500 dissolves readily in bacteriostatic water. Add the water slowly down the side of the vial and swirl gently until the solution is clear.
