    Using HCG alone for Low Testosterone

    Lack of availability and expensive price of hCG is really sad. I don't know why there is only availability of one FDA approved formulation of hCG in the US (pregnyl). It is simple to make and probably less expensive to make than most medications -- just purify urine from pregnant women. So...

    Where next, normal labs no drive

    Definitely, get the blood tests suggested by sammmy. There is a good chance that your problems is not related to testosterone. You just need to figure out what is causing them. Also, your symptoms could be consistent with sleep apnea. Discuss that with you doctor and see if a sleep study is...
