We don't know exactly what they will use in the final protocol if it works but we can get a good idea as everything that they will posibly use is listed in their patents.
I don't have their patents to hand atm but here is a list I copied from a post Michael Barry made on hairsite, these are some of the things listed as posibilities in the patents;
1-anti-androgen (finas, dutas, fluridil, spironolactone, ketoconazole, a few others)
2-channel opener (phenytoin, mionox, somthing else starting with "d"
3-EGF-antagonist (getfitnib, erlonitib, and a bunch of others)
4-antiinflammatory (COX inhibitors of various kinds)
5-retinoid (trenitoin, retinoic acid, some others)
6-anti-histamine
7-anti-bacterial
8-anti-microbial
9-fiberblast growth factor
10-ectodyslplasin, called EDAR
11-beta catenin
12-wnt protiens (older patent)
13-lithium compounds
It is also safe to assume that what ever combination of the above they will use in the final product (if it works) will be formulated into a topical.
Also from a post Michael Barry made regarding the process;
If you followed the patent, here is what you would do:
You would depilate, and wait three days.
On the fourth days, you'd wound. I'd also suggest getting on finas at this
time.
About day 3 or 4 or 5 thereafter (depending on whether keratinocytes are covering the wounded area as described in the patent), you'd start taking getfitinib or whatever egf-antagonist you can get your hands on. You'd also start taking an antihistamine, an anti-inflammatory. Clariton and Aleve would be two right off the top of my head. Parabens in shampoo could act as antibacterials for you if you use shampoo in this time. I think washing with nizoral and leaving it in for a few minutes before you wound would take care of any microbials during the experimental period because keto stays in the dermis for about seven days. Applying minoxidil to the wound around day 4 or 5 might be a good idea also. Its mentioned in the patent.
Keep using the stuff for a good six or seven days thereafter for certain. 10 is the longest they mention in the patent.
Thats about it. If you get hair, you'd probably be seeing it after about one month's time.
