Don't expect something miraculous in terms of hair from CB. It's just a side-free, probably weaker version of RU.
I've been talking to professionals in the field of male pattern baldness (dermatologists, pharmacists specialized in compounding), and they (who are not street joes like us) all expect that CB will be the real breakthrough. They know it, probably much better than the usual paper that we might google around.
The problem is: what are we using? which %? (might be too low, but also too high). The vehicle is probably a non-issues.
That said, I've just got the FT-IR analysis of 2 Kane batches and 1 WHP (Hengheda) batch.
The 2 kane batches have a high correlation (i.e. are the same thing), and have a low correlation with the WHP one. I.e., it's something different... probably a different molecule, or the same in different proportions (impurities).
This does not tell us nothing (yet) about which one is legit, but at least one is not.
