There was a long discussion on copper peptides and SkinBiology's 2nd generation copper peptides/SRCPs earlier this year and I thought I'd share my experience ( https://http://forums.owndoc.com/dermarolling-microneedling/Copper-peptides
I've been using the SkinBiology 2nd generation "copper peptide" products religiously for a year now and have found no improvement in my skin. If anything new lines and age spots have developed. I now realise that these products do not contain not GHK-Cu, but copper chloride and hydrolized soy protein. Pickart claims there is research to confirm the latter works, however my experience doesn't support that.
I followed SkinBios recommendations and started gradually and built up strength to the strongest products, and used them in conjunction with lactic/glycolic acids and microdermabrasion. I spent a good amount of money on what I am now quite confident is an ineffective product (ie the 2nd generation SRCP "copper peptides" not GHK-Cu. I didn't use SkinBiology's Super GHK cream or serum which Sarah identified as actually containing GHK-Cu...these aren't pushed on the SkinBio website or when you talk to the company).
Sarah has mentioned discussion forums being vehicles for company-promotion. I would hazard a guess that some of the frequent posters on the SkinBiology forum are from the company - making inspirational claims of amazing results that make you want to buy more products, with no before and after photos to back it up. Additionally SkinBiology has sent my order to the wrong address twice, and this last time they have told me I may have to wait 10 weeks before they find my lost order, let alone me even getting it (they said they addressed it incorrectly and will not offer a refund or to send a replacement order).
My experience confirms what Sarah has said on this forum about Skinbiology SRCPs and self-promotion by the company. I won't be buying any more products from SkinBio - they don't work, they don't disclose the concentration of ingredients, they have poor customer service.
I will, however, be using the GHK-Cu masks sold here (with GHK-Cu strength identified as it should be). It appears that the body of research is on this form of copper peptides.
Thanks very much Sarah for your insightful and informative postings on this topic.
