I use a 29 /.5ml which is 50 ticks on the pin
I mix 2.5 ml water with hcg so 1/2 ml is 1000iu and 1/4 mil is 500iu that measures 25 ticks on the slin pin 250iu is about 12 ticks, i dont use it weekly on cycle just at the end so i HOPE some one can tell you what dose they use in cycle 500iu is about the normal starting at 3 or 4 week .
