No, I doubt you have done much damage with the first and second shots, you would have if you had continued at the levels you put in your original post. You will be ok because we stopped this early.
Just imagine, you balls get blasted with a massive 5000iu of hcg they start working serious overtime for a few days and then get blasted with another massive amount while they are only just getting over the last one. Your balls are pretty delicate things and can only work at such a level for so long, The only way for you balls to adapt is to desensitize to to the massive amounts LH & HCG. This desensitizing is permanent.
500iu every day is a nice safe amount that will definitly make your balls bigger.
Sorry to scare ya mate, just worried about a fellow bro. drop me a message if you have any more questions and stuff
