Mixing different strengths


The easiest way is to mix eaquil amouts of both strengths 10mls of 1.8 mg + 10mls of1.2 mg = 3.0mg /20mls =1.5mg
so 1.8 + 1.2 is 3.0mg but thats has doubled the volume so you half the strength.

1.8
1.8 +1.2 =1.5
1.8 + 0.6 = 1.2
1.8 + 0.3 =1.05
1.2
1.2 + 0.6 = .9
1.2 + 0.3 = 7.5
.6
0.6 + 0.3 = 4.5
.3
0.3 + 0 = 0.15


You can also add zero strength if done in equal amounts you half the strength


1.8 + 0 =0.9
1.2 + 0 = 0.6
0.6 +0 = 0.3
0.3 + 0 = .15
