Katie Mullen shows her skin after 12 weeks using the copper peptide GHK-Cu, with visible changes between February and April. She emphasizes consistent long-term use and pushes back on claims that peptides don't work.
This one is for all the haters who say peptides don't work, because look at these results. This is almost the first day I started GHK-CU, and this was yesterday. Are you kidding me? Like, yes, I got some aesthetic stuff done also, but this is clearly like a systemic change. This was in February. This is the first week of February. This is April. You gotta stick with it. You gotta be consistent, but don't tell me they don't work. Hello.
