Heres a stupid question I couldnt find the answer for. when you order syringes are the markings on the side are in CC's or mg's. If they're in CC's how do you convert mg's into CC's. For example I need to shoot 250 mg of test twice a week how many CC's is 250mg?

syringes measure volume.

a 3cc syringe will hold 3ml. how many mg is 3ml? well, that depends on the concentration of what you're shooting. if substance is 250mg/ml then you need 1ml (or 1cc) to get 250mg.

1ml x 250mg/ml = 250mg

if its 100mg/ml then you need 2.5cc

2.5ml x 100mg/ml = 250mg
