My friends list has Jintrophin listing 4iu 10iu and 18iu.The 10iu come in fancy kits but the 18iu arnt in a kit persay.There is no water with them also.Ill see if i can borrow my friends camera and take some pics.Also i know people that have used the 10iu then ran out and could only get the 18iu's.They claim there was no noticable difference between the Two.
