Hi. I have a question on how u feel about growth factors. I work in a spa and we sell high end skincare products containing stem cells (human) and growth factors. Skinmedica and lifeline skin care as well as mybody. I have used them with ok results but I always end up going back to copper and retinal. They claim amazing results and stuff and our clients rave. I have not been impressed like them. What are your thoughts? Thanks

I think the copper peptides are better than anything being sold. But the FDA will not let us refer to the published science behind our products while our competitors can cite whatever science they have or imagine.
