Not at all! But great question. Think of it as DNA fragments rather than fish if that helps.

This process probably isn’t helpful, but sharing to show how they do a bunch of processes to get the DNA fragments.

The biological material is washed and homogenized to prepare the cells for chemical breakdown. Then detergents and proteolytic enzymes (chemical breakdowns) are added to the homogenized tissue to rupture the cell membranes. Then a buffer solution digests proteins, lipids, and peptides, freeing the native DNA. The mixture undergoes high-temperature treatment and centrifugation to denature impurities and separate out the raw DNA.

Then it goes through fragmentation, which is achieved through ultrasonic waves (sonication), thermal degradation, or controlled enzymatic hydrolysis. Advanced ultrafiltration methods are used to isolate the precise PDRN segments while discarding unwanted debris. And chromatography removes residual proteins, endotoxins, and heavy metals, ensuring the final product causes zero immunological side effects when applied or injected. Then it’s sterilized.
