I found this on bulkactives.com!!  I don't have the glucosamine so I can't make it yet.  Dimethyl isosorbide is a penetration enhancer, it is a rather expensive ingredient but you can substitute macadamia nut oil for it because it's way cheaper.

Distilled water               87.2% 
Dimethyl isosorbide           5%  
Glucosamine                     4%
Niacinamide                      2% 
Gelmaker PLUS              0.8%
Preservative (1)               0.5%  
Total Amount                  100
