I can't attest to the quality of it as I have never used it; however, with a pipette it shouldn't be hard to measure at all, infact it'll be simple!
In regards to how long it'll take, I'd message the forum gyno (or all around) guru for that: 'needtogetaas' - read threads in this board, he has helped a lot of people with his recommended combinations and one guys went reportedly went in 12 days!! Message him to find out how to treat it, he knows the score. He's helping me atm, waiting for products though, real cool guy.
Good luck bro
