If in the formula put EGF 5%, if the concentration is in ppm, it means that in this formula there will be a concentration of EGF at 250 ppm or not, if not, how many ppm is correct?

hello
EGF is sold as a liquid. The manufacturer does not tell the concentration of EGF in the liquid, so the concentration cannot be calculated. But using it at a rate of 1-2% can see results already.
