I thought I'd post this up since I get asked this frequently. It might save some trouble. Feel free to sticky this if needed.
How To Measure LongR3 IGF-1 by N4cer
I get mine 1mg dissolved in 2ml of BA. That makes it 500mcg/ml. With this being more diluted, less mcg is left in the slin pin.
So at this ratio, every 0.10 on a slin pin is 50mcg. That means that each iu is 5mcg.
If you have 1mg in 1ml of BA, each iu is 10mcg.
Draw the desired amount of bacteriostatic water into the slin pin and then draw the desired amount of IGF into the pin. Inject (preferably IM) and enjoy!
