It is probably good. I used some T1 pro about a month ago at 5 squirts/day. Ran it for a month and did not notice a whole lot really. Probably needed to up the dosage, but I have a new baby (came a lil early) and did not want to mess with any trans. Dropped the t1 and went with 10mg of SD/day.
If I was doing it again and taking into account the age of your bottle I would do 5-6 squirts 2x/day.
