Here is another problem with CS to contend with. This will direct link to a pdf about CS claimed percentages in powders.
If you don't want to read it all then I will post a snippet of it.
A US study by Adebowale et al. [23] has compared the amount of chondroitin sulfate in 11 different
formulations against a chondroitin sulfate considered to be a chemical reference substance by the
European Pharmacopeia [17].
The latter is of bovine trachea origin and manufactured by Bioibérica
(Barcelona, Spain). High performance liquid chromatography (HPLC) data showed that the amount of
chondroitin sulfate varied from approximately
10% to 110% of that claimed on the label [23]. Moreover,
using a titration method, the amount of chondroitin sulfate in 32 products purchased from pharmacies
and health food stores
varied from 0% to 105% of the label claim (26/32 contained <90% label claim
and 17/32 contained <40% label claim) [2
Not surprisingly, the bovine sample had similar proportions of chondroitin-4-sulfate (61%)
and chondroitin-6-sulfate (33%)
We know 61% of the bovine trachea powder is 61% CS-A but we don't know how much CS we are getting as shown above as claimed on the label. The 6-sulfate is CS-C.

In other words, if the bovine trachea CS is legit then we could replicate Dr. Morrison's experiments to a tee. If he used only CS-A then take his dosages which grew hair and divide by .61. Which would be either 10 grams/.61 or 16 grams per day or 6 grams/.61 ~ 10 grams.
If he used the A and C powder like off the shelf then just take the dosages his patients used which is 10 or 6 grams PROVIDING the powder is LEGIT.
