I went recently to three urologists who were all very uninterested in helping look at and treat/medicate me for low free-testosterone. I finally was authorized to see an endocrinologist who prescribed me to take 0.5 milliliters (100 mg) of testosterone cypionate, injected into my upper thigh once per week. It'll be a few weeks, into September before I can get a Free-T blood test check and see if that dosage is OK or not. The generic Androgel 1.62 made no difference whatsoever in terms or raising my free-T level, although it did increase my overall total testosterone. I've stopped applying it now. No feeling yet as to improved libido, that will hopefully come in 3 to 6 weeks after the T injections began per the internet. I'm 76 years old now. For at least 4 years now, my free-T has been substantially below the bottom of the range. Latest result was 3.8 in July versus a normalcy range of 6.6 to 18.1. I have zero libido and 100% ED.
