how to calculate mg/ml and amounts of oil solvent hormone etc...

generally 1 gram of powder/hormone will displace .85ml of volume when dissolved in a liquid. however this varies a bit but usually is not significant. somtimes things will displace a lil over 1ml per g though, so this is just a rough estimate, although pretty accurate usually. if you know the real displacement per ml, this is the most accurate way.
if you dont know the real displacement per ml, this method shown here will potentially be more accurate usually.
to find out how to make a certain mg/ml concentration you need to do a few things:
lets say we want 300mg/ml and want 100ml total. and lets assume that 5%ba will keep this in solution.
obviously we will need the final volume to be 100ml
100ml x300mg in each ml
100x300=30,000mg total hormone used
1000mg=1g
30,000mg=30g
since 1g=.85ml then 30g=25.5ml
so now we want 100ml and know we need to add 30g hormone to achieve 300mg/ml. since 30g=25.5ml, we now have 74.5ml left to displace with something else.
now we need to add enough ba to achieve 5% of the total volume.
100ml x .05(.05=5%) =5ml ba
so we had 100ml total and subtracted 25.5ml to make room for the hormone, then subtract another 5ml to make room for the ba, which leaves us with 69.5ml. this is how much oil or pg etc... we will need to add.
to get to 100 total ml we use 30g hormone which is equall to 25.5ml
add 5ml ba
add 69.5ml oil
25.5+5+69.5=100
now everyone should be able to figure out how to make any mg/ml in any total amount of ml. if you still dont understand how to make 200mg/ml with 50ml total, or 150mg/ml in 75ml total, well god help you, you should give up
