basic conversion, your pins are 33 iu's or 1/3 ml going off the standard 100iu's equals 1ml scale in regards to insulin. so if you had 1mg (1000mcg) of des mixed with 1ml (100 iu's) of bac water you would have 10mcg per 1iu "tick" or"hash" mark on the syringe. if you put 2ml in the vial then dosage is 5mcg per 1iu etc.. IMO the 50iu and 30iu are the absolute best pins to use when dealing with peps cuz you can get extremely accurate on single digit iu's so you dosage is 100%
dosage is all in how you want to run it then adjust your mixing accordingly to accommodate your using the pins to dose...
when I get my stash lol im looking to see how 20 or 30mcg will work, may split dose or may just do a lump dose once preWO or PWO, all boils down to how you want to experiment lol
