i have never heard about 15.000ui in 1 dose!!for what i know it is very much even 5000ui..i have had problems in the past from too much HCG..and because i have used too much i was back in the state i was before the PCT..and guess what?you can't do anything

if you have problems after a cycle from steroids HCG will raise your's LH levels,but if you have problem after too much HCG,i don't know any solution to solve the problem..you must way some good months to regain your's sensivity to the drug,or some say that you can damage your's gonadal permanently!!..i don't know if this is true
