Fina Conversion Formula

[brownpaperbag04]

Hey again fina-holics...I have one last question that I've searched and searched for but I can't find a straight answer. WHAT IS the formula you use to get the correct final solution to inject? (how many fina pellets/how much BA & BB/how much oil). I'm sure there is a set formula for this...the only one I found says you do the following:

Say you want to have an 80mg/ml dosage...you do however many mg of fina you're going to use...say one cart (2000mg)/80mg = 25ml
That 25ml is the total amount of solution that you should end up with at the end. Then you figure 20% of the total solution to be BA/BB (in a 5 to 1 ratio)...so in the example it's 5ml of BA/BB. You figure the pellets themselves (once disolved) will take up 2ml. That leaves 18ml left...so you use 18ml of oil.

--Formula Recap--
Total Fina/Dosage Wanted = Total Solution in ml
.2 * Total Solution = Amount of BA/BB needed to dissolve
1000 pellets = 1ml
Total Solution - (BA/BB + Pellets) = Amount of oil needed

Does this look right to anyone? ...If not please let me know the correct formulas.

If possible, get a precise measuring cylinder and use it to make up the volume to 25mL... it's much more accurate than assuming what the powder's dissolved volume will be.

Otherwise, looks good.

To make up the volume, dissolve your fina in a small amount of oil, inside the measuring cylinder. Then, add oil until it reaches the desired volume (after the fina is completely dissolved; don't make up the volume in a cloudy solution).

Once it's all been dissolved, made up to volume and mixed, any that sticks to the sides of the cylinder won't affect the concentration of the rest.

Have a good one!
