Hey guys please correct me if im wrong but if i mix my 5000iu HCG with 10mL of bacteriostatic water then that would make the mixed HCG 500iu in 1ML. I understansd that it only has a shelf life of 45 days once mixed. But if i pin it at 250iu twice a week that would be 500iu a week. It would take me 70 days to finish my 10mL vial of HCG. Would the HCG be no good after 45 days? This is my first time using HCG so just trying to cover every angle.could i also get the best mixing calculations for 250iu twice a week if i decide to preload syringes as i think it might be easier. thanks for all the help. really appreciate it.
