Ah it was just chemo. He knows nothing...hehehe. I would not put more dmso in becasue we have found out that 10% is the threashold for it. IMO the formula is very good. Trying to gain .5 or 1% more is futile when you probably won't notice the difference.But thats just me. With the dmso in there it will be hard to gain any points on the %.But on the other hand nothing is perfect it can always be improved.SO keep trying to increase it I guess if you add up 5 differernt things at 1% increase thats 5% increase. I just don't think the heating is worth it(unless the ph is not in solution) Well Talk to ya..
