Once a week only 500mcg's. To much and you will do the same thing that you are already doing running gear and shut down your own natural production. Trust me this works. You will notice a decline coming into the end of the week but as soon as you take another shot your testicles drop and it starts all over. It's what we have to deal with staying on or doing high dosages. Take that shot once a week and you'll be ok. The only thing I think might be different is maybe you need more or less. Maybe a shot closer in duration like every 5 days instead of 7 days. That's up to you to decide your personal response.
