1 mcg = 0.001 milligrams
1mg = 0.0001 grams
So 200mcg X 60ml = 12000mcg = 12mg = 0.012g
So indeed 100 bottles coud be made from 1.2g. However u r thinking about this the wrong way. U cant compare 1g of test with 1g of clen powder. I am sure there is markup but it is based on dosage strength. If for example if test was 10X stronger than it is know then the 1g of test could be substituted with 100mg and soon a single vial would be very expensive bc not as much is needed. it is all based on dosage strength.
