Hello,
For the face products, the skinbio site lists strength of copper peptides from (I believe 1-30). Where wold folligen spray fall on this rating scale?

Thank you

Dear jaha:

Thanks for posting your question - Since all Folligen Therapy products (Spray and Cream) and Hair Signals Therapy have the same copper peptide concentration, we don't list a comparative "strength scale rating".

But comparing it to the skin products, it would be around an "8" (...similar to Super CP Serum).

Best Wishes,
