to figure out how many ml you need you need to know
the strength of the PCT..IE...1800mg/30ml...so here there is 1800mg(s) in a
30ml bottle. Now divide 1800 by 30 = 60. So we now know that in every 1ml
there is 60mg(s) of PCT at least with this bottle. Now that we know that, we
then take our wanted dose amount of 40mg and divide 40 by 60 = 0.666666667
or better yet 0.67ml of a 1ml syringe! Hope this makes since
