Doesn't say in his info..

although he may sound like a youngin... i have a good friend.. and cant do the simplest math conversions either.. but he can eat and lift like theres no 2morro, and sits at sub 10% bf 200lbs. which is better than I, and I sit here and do math and macros all day, lol

or maybe hes young i dont know, either way its a 4th grade math problem( not flaming just trying to let people know some people just doesnt click as well)

yes if theres 200mg in 1 ml... then a half of a ml will have 100mg.. so you need to add another half of ml too get the to 300

1ml=200
1.5ml=300
2ml=400
2.5ml=500

(not a recommendation, just a lesson)
