Approval takes more than a label.

Check off the idea

Understand the canceled request

• The request was about pharmacy ingredients

  The September 30, 2026 check found Selank in FDA’s list of canceled requests to allow ingredients for pharmacy-made medicines.

  FDA calls the Selank ingredient in that list “Selank acetate.” The extra word is part of the ingredient’s chemical name, not an approval.

  Individuals or groups had asked FDA to allow these ingredients, then took back their requests.

• Canceling a request is not approval

  Taking back the Selank request did not give FDA approval, and FDA still warns about possible harm.

  FDA worries that clumps of Selank or unwanted material mixed with it could make the body treat it as an invader.

  The entry does not name which ways of giving Selank this concern applies to.

• Keep the date attached

  The FDA page marks its content current as of April 22, 2026. The page does not give the date when the Selank request was canceled.

A note to keep

Understand the pharmacy question

Compounding means making medicine to meet a specific need, rather than using a ready-made product from a factory.

Federal law has a list of extra ingredients pharmacies may use to make medicines. Selank was not on it at the September 30, 2026 check.

FDA also groups ingredients while it considers requests to allow them. Selank was in none of those groups at that check.

Canceling a request does not let a pharmacy use Selank under the rules reviewed on September 26, 2026.

FDA has not published a plain statement of what canceling the Selank request means for pharmacies. A claim that this made it lawful to use needs an explanation of the rule being relied on.

Check the proof behind the words

• A drug code is not approval

  FDA keeps a list of products with identifying numbers called National Drug Codes, or NDCs. A number on that list is not proof of FDA approval.

  The Selank entries checked September 30, 2026 were powders for making products, not medicines ready to take.

• A foreign history does not settle U.S. status

  In Russia, Selank had permission to be sold as a medicine for anxiety. Whether that permission was still in force was unclear at the September 30, 2026 check.

• Ask for the exact basis

  Ask which product and which rule the claim refers to. Bring that answer to your doctor or another licensed health professional rather than treating a badge as proof.
