Evidence & cautions A guidebook chapter
Claims that deserve a pause
Before paying, turn a big claim into a small question that has a checkable answer.
Semax facts: September 30, 2026. Care rules: September 26, 2026.
A registration claim needs unpacking
As of September 26, 2026, registration with the Food and Drug Administration, or FDA, does not mean approval of a business or drug.
A drug code in the FDA directory does not mean approval either.
Ask which exact product has approval, and ask for the record. A badge cannot answer that question.
“Research only” is not a care plan
The FDA recorded Semax offered online with a research-only label in its review checked September 30, 2026.
Under the FDA position checked September 26, 2026, writing “research only” on a product does not make it legal to sell as an unapproved human treatment.
“Research only” describes a laboratory product, not a medicine for your care. A seller’s claim that it treats people does not turn that label into permission.
“Pick your treatment” skips the main question
In May 2026, the Federation of State Medical Boards adopted guidance saying that a treatment-menu choice by itself does not justify care.
The guidance also calls for a way to ask your treating doctor or other health professional more questions after the first answers.
This is advice for the state bodies that oversee doctors. Each state makes its own enforceable rules.
A claim of no unwanted effects
The FDA found that most Semax studies did not discuss side effects.
That does not support a claim that Semax has none.

Keep this in mind.
Ask for the product record, the human evidence and a real chance to ask questions. A polished page is not an answer.
