Are growth factors like TNS Recovery Complex safe to use?
I think you’ll feel comforted by knowing how they are made. Since our own cells make these factors, they are completely natural. To make a long story short, a certified young cell line is grown in petri dishes in the lab. The cells line the bottom of the dish and a thin layer of liquid food called media (like a soup) covers them. As the cells grow, they secrete their own growth factors into the media. The media is harvested, purified and concentrated and put into a serum. I hope this helps! Dr. I
