Since there are two types of Copper Peptide on the web.

and pure Copper Peptide powder

Doubt: The liquid form is defined as a maximum of 3% in the formulation. The liquid form is a solution containing 1 ppm of Copper Peptide. Added in the 3% formulation is equivalent to pure Copper Peptide powder. Only 0.000003% in the formula, but the pure Copper Peptide powder says that it can be used up to 1% at all. The concentration is very different as described. So I want to know if using the maximum prescribed dosage will be effective from the two. Will the expensive 1% Pure Copper Peptide powder be more effective than the 3% Liquid Copper Peptide ?

Or if I misunderstand anything, let me know.

Sorry, I misunderstood. The liquid Copper Peptide contains Copper Peptide 1000 ppm, not 1 ppm.

Make the number 0.000003% to change to 0.003%

But still the question above.

hello

Correct the concentration of Copper Peptide powder, use between 0.01-0.1%.
