Another thing you can do is get some extra AA. MR will send you 3 or 4 mL of AA seperate for free if you ask. You can also get some at
www.researchlabsupply.com. then you can further dilute your lr3.
It makes the dosing a little easier. The math is fairly simple if you go about it in the right way. What I do is take your total amount of lr3 (in the units you are going to dose in)...in your case 1000mcgs. Then its already in 1mL of AA which is also 100units (1mL = 1cc = 100units) So you then divide your total amount of lr3 by the amount of your dilution in units.
At the moment you have 1000mcgs/100units = 10mcgs per tick on pin.
If you add one more mL of AA to it you now have 1000mcgs/200units = 5mcgs per tick on pin.
More dilution can be helpful especially when using lower dosages.
