Goralatide Reference

Plain English

What it is

Goralatide, also called Ac-SDKP, is a tiny natural piece of protein (a four-part chain called a tetrapeptide) that the body makes by snipping it off the end of a larger protein named thymosin beta-4. It is not an FDA-approved medicine for any condition. It is studied and traded as a research chemical, not a finished drug.

What people use it for

In lab and animal studies it has been looked at for calming inflammation and slowing fibrosis, which is the build-up of stiff scar tissue inside organs such as the heart, lungs, and kidneys. People interested in protecting those organs from scarring sometimes look at it for that reason.

What the science shows

Most of the supporting evidence comes from rodent (rat and mouse) studies, not from people. The handful of human studies have been small and early, and the most advanced one tested it as part of a kidney-function test rather than as an approved treatment. There is no large, strong proof that it works or is safe in humans.

The catch

It has no FDA approval, so it has not been shown to be safe or effective in people, and nearly all of the encouraging data is from animals. Human research stays small and exploratory. For research and educational purposes only. Not medical advice.

Reference summary

Published work is mostly preclinical, focused on antifibrotic activity in cardiac, pulmonary, and renal models. Clinical antifibrotic programs have been small and exploratory.

Regulatory and posture

Categories

Recovery, Longevity

Aliases

Ac-SDKP, N-acetyl-Seryl-Aspartyl-Lysyl-Proline

Evidence posture

preclinical - Mostly rodent antifibrotic data. Human clinical antifibrotic programs are exploratory and small. No FDA-approved indication.

Regulatory status

No FDA-approved Ac-SDKP / goralatide drug label. Ac-SDKP is the natural N-terminal tetrapeptide cleaved from thymosin beta-4 and has been studied as an antifibrotic and hematopoietic regulator.
