Hi Dazed,
I currently use folligen and hair signals, which I mix 5 drops with my minox. Tricomin and graftcyte are the only copper peptides with scientific data backing them up, the peptide they use is different in folligen and hair signals as the patent is owned by a different company, despite being found by Dr Pickert, who owns skinbiology.com.
That said, the folligen and hair signals have many more peptides in than graftcyte/tricomin, only they have not been scientifically tested, probably because of cost, as Dr Pickert was working for a company when tricomin/graftcyte was tested.
I've found testimonials on-line of people using folligen post op and reporting positive experiences with it, so i'm sure it's just as good as graftcyte, or possibly better....hair signals is really quite new, so not found many customer experiences with that product as yet.
