Yeah, I believe the PTD-DBM they are referring to is actually PolyR8-DBM according to this early patent and what they most likely used in their wounding study. Although we don't know FOR CERTAIN if it's the the same poly-peptide they used in their hair study, we know that it should have the same mechanism of action and they have used it before. It's the best place we have at the moment to start, although I think it would be good if someone can test it to make sure there isn't something they are leaving out of their present patent disclosure.
Btw. I posted a link to that patent earlier in this thread back on Dec. 10 (

Edit: Also, there are lots of labs which can create custom peptides. The process is in principle fairly simple, however it can be a lengthy (costly process). Generally the longer the amino acid sequence, the more expensive it is to create. Some modifications to an amino acid sequence can be more tricky and hence more expensive than others. At the fundamental level, all your doing is biasing one side of an amino acid and the opposite side of another, so that they join in the correct sequence. Easily in principle but a bit challenging in practice if high purity is required. The cost could easily be in the neighborhood of a few hundred dollars per gram, although hopefully someone is willing to do it cheaper.
