“P21 peptide is the same thing as the p21/CDKN1A protein.”

Misleading

No. P21 peptide is a small compound made in a lab. CDKN1A is a human gene. It makes a protein also called p21. The shared short name does not make them the same.

What kind of evidence this is

Regulatory or product record. This answer uses an official regulator record or a specific product label.
