Did you get that from a body-building site/supplement company site?Benefits from TB-500 (Thymosin Beta 4)
TB-500 Can Help you Recover Fully and Fast!
Clinical studies done on race horses have proven that TB-500 can provide the following benefits:
Increased muscle growth along with huge increases in endurance and strength
Relaxed muscle spasm
Improved muscle tone
Increased exchange of substances between cells
Rapid tissue repair
Stretches connective tissue
Helps maintain flexibility
Reduced inflammation of tissue in joints
Prevents the formation of adhesions and fibrous bands in muscles, tendons, and ligaments
This potent peptide can be purchased from RUI-Products.com, albeit for research purposes only.
Certainly the stuff I have read places regenerative processes as it's beneficial action.
As an example, the quote below is in regard to the known mechanisms of action in the body for TB4 (natural form/not synthetic).
'When trauma occurs, Thymosin beta-4 is released to increase the healing of that trauma. It also acts to prevent the formation of adhesions. This means less scar tissue, and hopefully, more flexibility.'

The strength and endurance benefits are merely unsubstantiated claims for the synthetic version of TB500 being sold. The following article only states that increased muscle mass was 'reported' to have occurred in horses but has had no reported enhancement in humans.

The synthetic version has been manufactured to more efficiently fit receptor sites.
This is all a bit irrelevant though seeing as nobody tested positive to its use. But even if they did there is no clinical evidence of gains in muscle size, performance, or endurance.
