I think the active ingredients of American Crew products and trichomine are the same. And depending on which amino acids are bound to Copper Peptide, their properties also change. ProCyte's patent refers to the order and method of combining certain amino acids with Copper ions. In fact, Copper is present in human plasma in combination with amino acids, and ProCyte artificially synthesized it. in a form that facilitates skin penetration..
In other words, Copper is not all the same Copper.
However, we have not been able to confirm exactly what percentage American Crew uses in terms of content.
The burden of price is also unfortunate. However, in the case of Spray, a small size (60ml) is sold, so I think it would be less burdensome..
Then I'll go... ^-^
