Thymosin beta-4 TB4

The full-length natural peptide that TB-500 is derived from, studied mostly in animals for tissue repair. A related eye-drop version has been tested in human trials for dry eye and corneal healing, but broader body-wide human research is still limited.

Also known as Full-length TB4, Thymosin Beta 4, THYMOSIN BETA 4 ACETATE, Thymosin beta4 Acetate, Thymosin beta 4?, Thymosin b4 (cattle), orb1910607

Clinical data

What has been reported in the literature and by users. This is a record of what is done, not a recommendation.

Typical dose Not established for systemic human use (a related eye-drop formulation has been trialed for a specific indication)

Reported range Animal studies: variable by model; eye-drop trials used a specific ophthalmic concentration for dry eye/corneal healing

Route Subcutaneous injection (systemic, unregulated use) or topical eye drop (trialed formulation)

Frequency Not established (systemic); as directed per trial protocol (eye drop)

Duration Not established

The full-length natural peptide that TB-500 is derived from; broader body-wide human safety/efficacy data for injectable use is limited, and injectable products are sold only as unregulated research chemicals.

Where this comes from Animal studies (systemic use); published clinical trials (eye-drop formulation)
