You could, but the absorption would be greater with the IPM. When I did a 1-test cycle I homebrewed my own recipe. heres what I used:
40% Iso prop alcohol
25% IPM
10% prop glyc
10% oleic acid
10% DMSO
5% d-limone
Got all my stuff from lemelange also. If I were you I'd wait the two weeks until you can make a proper mix.
