This will very.
You will have to decide the brand, and what it will cost.
How many iu that includes? 100iu etc..
what dose your running? Say 5 iu ed.
How often ..5 days a week or 7 days a week?
So lets make it simple. How many iu's your gonna run for 6 months.
5iu x 7 days=35 a week
35iu x26 weeks= 910 iu's you will need for 6months .
So if 100iu come in a box, multiple x10boxes =1000iu.
This is what you will need. Then add up your price$$x 10boxes=??
Hope this helps. Adjust accordingly.
