Negative, you are just going to confuse the man!
Those syringes are made for insulin, thus the IU markings are for insulin.
A U100 insulin syringe is equal to 1cc/ml. The 50IU marking on the syringe is .5cc/ml. Insulin is dosed different then the Human Chorionic Gonadotropin (HCG) and Human Chorionic Gonadotropin (HCG) concentration depends on how much Human Chorionic Gonadotropin (HCG) IU amount you started with and water used.
Adding 5.5 ml to 11,000 iu of Human Chorionic Gonadotropin (HCG) will give you 2,000iu of Human Chorionic Gonadotropin (HCG) per ML/CC. Your 100iu insulin syringe is equal to 1ml/cc. 25iu on the syringe or .25cc/ml equals 500iu.
Any confusion now??
