doses of Thymosin Beta-4 used in research

Not approved; synthetic thymosin beta-4 has a completed IV phase 1 in healthy volunteers (42-1260 mg) and phase 2 trials of a topical gel and 0.1% eye drops, and recombinant thymosin beta-4 (NL005) has a registered IV phase 2 trial in China (NCT07586865, not yet recruiting). These are the amounts specific labels and studies used, linked to each source. They are references, not recommendations; a prescription label takes priority.

what the numbers mean · where they come from

terms and sources

Label amount or measured amount. The calculator starts from the amount printed on the vial. A lot certificate’s measured content (net peptide content, in mg) can replace it for the vial that was tested. HPLC purity is a share of peak area, not a mass, so a purity-only correction is shown as an estimate. See HPLC, certificate of analysis and how to read a peptide COA.
Concentration. Amount in the vial ÷ water added. Terms: reconstitution, bacteriostatic water, lyophilized.
Syringe units. A volume: 0.01 mL per unit on a U-100 syringe, 0.025 mL on U-40. Units say nothing about the compound until the concentration is known.
Cost per draw. Vial price × amount per draw ÷ vial amount, from the price per mg of a current offer. Offers come from the Thymosin Beta-4 price comparison; certificates from the COA library.

Arithmetic only, on the numbers entered. Amounts from labels or trials are cited references, not recommendations; PeptideTech does not give personal use instructions and does not test products.

short answers

Thymosin Beta-4 calculator questions

How much bacteriostatic water do I add to Thymosin Beta-4 10mg?

Any volume the vial holds; 2 mL gives 5 mg/mL, so 10 units on a U-100 syringe holds 500 mcg. More water makes each draw read more units. The table below shows 1–5 mL for every Thymosin Beta-4 vial size on sale.

What changes the calculated concentration?

Only two inputs: the amount of Thymosin Beta-4 in the vial and the water added. 10mg in 2 mL is 5 mg/mL; twice the water halves it, and the amount per draw then reads twice the units. A lot certificate’s measured content, where printed, replaces the label amount. HPLC purity is a share of peak area, not a measured mass, so it is shown only as an estimate.

What doses of Thymosin Beta-4 were used in research?

Not approved; synthetic thymosin beta-4 has a completed IV phase 1 in healthy volunteers (42-1260 mg) and phase 2 trials of a topical gel and 0.1% eye drops, and recombinant thymosin beta-4 (NL005) has a registered IV phase 2 trial in China (NCT07586865, not yet recruiting). The table on this page lists 3 sources with amounts, schedules and links.

What does Thymosin Beta-4 cost per mg?

The lowest current US price is $40.00 for 5mg at Amino USA (about $8.00 per mg, checked 2026-11-06). The calculator turns any vial price into cost per draw.
