Ok everything I ordered came in for my melanotan II and I just did my first pin can you guys verify that I did it correctly??

took the 10 mg mt II and added 2 full 100 iu syringes worth of BAC water to it
I then mixed it together
Took my fresh syringe and took out 10 Units of the mixed melanotan ii/bac water substance
alcohol swabbed my injection site and did a sub-q injection which was completely painless/no blood

so my main question is with that injections if I am correct I injected .5mg of melanotan II correct?
