Sorry if someone already this but,I just ordered 1-T PRO w/DMSO. I assume these come in different bottles,do I just add the entire contents of DMSO to 1-T PRO or is there another way these are used
You are correct.
So I take it the whole bottle of DMSO will fit in the 1-T PRO bottle without any overflow
Yup, pour it in, no overflow and then shake the hell out of it. Enjoy.
