Can't keep a Hard On

[xhooker]

I'm 65 years old my USA Dr in San Diego said after blood tests my levels where spot on for IGF and Test.

Can anyone please shed any light on why I can not keep a Hard on.

My Asian girl friends are all from 19 to 26 and good looking but after 5 minutes it starts going soft
until it falls out - Help any ideas

Daily - 2.5 iu of blue top HGH

Weekly - 125 mg or 0.5 ml of Test Enanthate Injection
- - - - - 3.0 ml of Vitamin B complex

Is it what I'm taking or my age ?

Any ideas would really help otherwise will have to give up my hobby.
